key message #1:

cyclonic sw`erly to w`erly flow aloft and embedded shortwave
disturbances affect our region through wednesday night as a primary
mid/upper-level trough deepens and approaches our region from the
west. on the synoptic-scale and at the surface, a strong and wavy
front extended generally ne`ward from the southwestern great lakes
and across southern lower mi and southern on to near the border
between qc and ny/vt/nh early this afternoon. this front is expected
to waver in the same general area through tonight as multiple, weak
lows move ne`ward along the front. on wednesday through wednesday
night, a stronger low is still expected to deepen as it tracks
ne`ward along the front, from the southwestern great lakes to
southern qc. this evolution of the low should allow the trailing and
strong cold front to sweep se`ward across our region late wednesday
afternoon through the evening. behind the front, a surface ridge
builds from the north-central united states through daybreak
thursday. net low-level waa in the warm sector will contribute to
overnight lows reaching mainly the 50`s to lower 60`s overnight
tonight; well-above average for this time of year. afternoon highs
should reach mainly the upper 60`s to lower 70`s on wednesday, ahead
of the cold front. near-record warm highs are forecast. strong low-
level caa behind the cold front will contribute to lows reaching the
mid 20`s to lower 30`s around daybreak thursday.

through this evening, isolated and organized showers and
thunderstorms amidst moderate to strong effective bulk shear remain
possible in northern oh and nw pa due to the following reasons: low-
level convergence/moist ascent along a lake erie lake breeze front
that should advance a few miles inland from the shore from the ne
side of cleveland through erie county, pa before the lake breeze
dissipates early this evening; moist isentropic ascent aloft, ahead
of shortwave disturbances, and low-level convergence/moist ascent
along surface trough axes accompanying the shortwaves. these lifting
mechanisms are expected to release weak to moderate and primarily
surface-based mucape over land and elevated mucape over the
relatively-cold/stable lake erie marine boundary layer. there is a
small risk of damaging wind gusts with these organized storms
through early evening courtesy of steep low-level lapse rates and
moderate dcape before the boundary layer over land starts to
stabilize via nocturnal cooling. the potential for small to
marginally-severe hail should increase through this evening as mid-
level lapse rates steepen to near 7c/km to 8c/km as an eml plume
overspreads our area from the wsw and allows mucape in the hail
growth zone to increase as ambient melting levels remain near 10kft
agl. the potential for severe convective weather through this
evening still appears to be non-zero, but minimal.

the predawn hours of wednesday morning are when we are most-
concerned about severe thunderstorms in our cwa. a wsw`erly
nocturnal low-level jet (llj) of at least 40 to 50 knots, at/near
925 to 850 mb, should form over our region. this llj will enhance
moist isentropic ascent, including ahead of the shortwave trough
axes, and enhance low-level vertical wind shear and primarily
surface-based esrh (i.e. esrh values should increase to near 150 to
250 meters squared per second squared). deepening of lows along the
surface front should back surface winds somewhat, which should also
enhance surface-based esrh in our cwa. primarily surface-based
mucape should remain weak to moderate in the warm/moist sector and
effective bulk shear will remain moderate to strong as tropospheric
winds continue to veer and especially strengthen significantly with
height. mid-level lapse rates should remain steep and mucape in the
hail growth zone should remain sizable through about daybreak,
before the eml plume exits ene`ward. accordingly, organized
convection that develops upstream of our region late this afternoon
and evening should persist generally e`ward across our region as a
qlcs and pose the risk of a tornado or two, as mixed layer lcl`s
remain favorable, and pose the risk of damaging hail up to golf ball-
size. damaging straight-line wind gusts are also a concern because,
for example, the qlcs should exhibit a fairly deep/strong cold pool
and dcin should be limited as synoptic-scale low-level warm/moist
air advection persists in the pre-storm environment and limits
nocturnal cooling.

during the day on wednesday, effective bulk shear is expected to
remain moderate to strong as tropospheric winds continue to veer and
especially strengthen with height. primarily surface-based esrh and
mucape, respectively, are forecast in the warm/moist sector,
especially given the expectation of peeks of sunshine and daytime
heating. esrh should remain sizable as the aforementioned stronger
and deeper surface low should cause surface winds to back somewhat
and help enhance low-level vertical wind shear. mid-level lapse
rates should be paltry, though, due to the lack of an eml plume.
the biggest question for wednesday`s forecast is how much renewed
destabilization of the warm/moist sector boundary layer will occur
in our cwa given the expectation of mostly cloudy sky and residual
outflow from earlier convection. if sufficient daytime heating
yields weak to moderate and primarily surface-based mucape amidst
steep low-level lapse rates, then another qlcs along the cold front
with a threat for tornadoes and damaging straight-line wind gusts
would likely materialize. we will continue to monitor this potential
closely. otherwise, if mucape remains paltry, the cold front
passage would likely be accompanied by isolated to scattered showers
and sub-severe storms. note: showers and storms are expected to
produce periods of heavy rain as the low-level warm/moist air
advection from the gulf yields near-record high pwat values in the
warm sector. training convection is expected along the front and
along the axis of tonight`s wsw`erly llj as mean mid-level flow
exhibits a large component parallel to the front and the llj`s major
axis. excessive rainfall and localized flash flooding are not out of
the question. once the cold front sweeps se`ward through our region,
rain may mix with and then change to wet snow via nocturnal cooling,
the wet-bulb effect, and strong caa at the surface and aloft before
precip along the upper-reaches of the front exits our region by
daybreak thursday. any snow accumulations should be less than a half
inch.

key message #2:

dry weather and much colder air temperatures are expected in the
cold sector on thursday as the surface ridge continues building
e`ward, a primary trough axis aloft sweeps e`ward over our region,
and shortwave ridging aloft follows. daytime highs should reach only
the 30`s in nw pa and the mid 30`s to lower 40`s in northern oh. the
ridge exits e`ward thursday night and allows a warm front to sweep
n`ward through our region as a clipper-type low pressure system
approaches from the north-central united states and vicinity. a mix
of primarily rain and snow is possible via moist isentropic ascent
along the upper-reaches of the warm front. lows should reach the mid
20`s to mid 30`s before midnight and be followed by moderating
temperatures as waa strengthens at the surface and aloft ahead of
and especially behind the surface warm front. as the clipper moves
e`ward across the northern great lakes region on friday, the
trailing cold front sweeps e`ward across our region. rain showers
along the surface cold front may be followed by a rain/snow mix
associated with the upper-reaches of the cold front as cold air
deepens behind the surface front. daytime highs are expected to
reach mainly the 40`s to lower 50`s ahead of the cold front. a
strong low-level wind field is expected to accompany the clipper. at
least advisory-criteria peak wind gusts (46 to 57 mph) are possible
due to the following: diurnal convective mixing of the boundary
layer tapping into stronger flow aloft; deep mechanical mixing of
the boundary layer tapping into stronger flow aloft for several
hours behind the cold front as low-level winds/caa strengthening
with height promote steep low-level lapse rates. odds favor dry
weather friday night as a ridge at the surface and aloft moves
e`ward through our region. lows should reach the 20`s to lower 30`s
amidst low-level caa behind the cold front.

primarily sw`erly to w`erly flow aloft and embedded trough axes
should impact our region this weekend through tuesday. at the
surface, our region should mainly be located in the cold sector, but
a warm front should sweep n`ward through our region saturday night
into sunday and be followed by the e`ward passage of a strong cold
front later sunday into sunday night. additional periods of rain
and/or snow are expected courtesy of the front passages and moist
isentropic ascent ahead of the trough axes aloft. mainly near or
below-average air temperatures are expected. for example, our latest
forecast calls for highs to reach only the lower to mid 30`s on
monday and only the mid 20`s to lower 30`s on tuesday. however,
above-average high temperatures are forecast in the warm sector on
sunday. note: a primarily w`erly to nw`erly mean low-level flow of
sufficiently-cold/moist air over/downwind of ~3c lake erie may
generate lake-effect snow monday into tuesday.

vfr will continue early tonight, but all eyes continue to be on
the severe thunderstorms currently developing in illinois. these
thunderstorms will organize into a line that will move west to
east across all terminals late tonight and early wednesday
morning. adjusted the timing of this line at each terminal based
on the latest high-res model guidance and current radar trends.
the line of thunderstorms looks to reach ktol and kfdy in the
07-10z timeframe, kcle and kmfd in the 10-12z timeframe, kcak
and kyng in the 11-13z timeframe, and keri in the 12-14z
timeframe. the main impact will be cigs and vis dropping to
mvfr/ifr along with heavy rain and gusty winds of 35 to 50
knots. the thunderstorms will be strongest at ktol and kfdy and
should gradually weaken with eastward extent.

behind the line, showers should be fairly persistent most of the
day wednesday leading to continuous mvfr conditions. the
steadiest rain will gradually exit from west to east in the mid
and late afternoon, but mvfr will continue through the end of
the taf cycle. confidence is increasing that round two of
thunderstorms wednesday afternoon will develop southeast of the
region given the clouds and widespread showers much of the day.

s winds of 5-10 knots this evening will gradually turn sw late
tonight and early wednesday morning and increase to 10-15 knots
with gusts of 20-25 knots. winds will turn wsw by wednesday
evening, with gusts of 20-30 knots at times.

outlook...non-vfr likely in rain briefly transitioning to snow
wednesday night into thursday. non-vfr may return in scattered
rain/snow showers on friday. confidence is increasing for
widespread strong west to southwest winds on friday.

.marine...
a stationary front will reside across lake erie tonight with
potential for showers and thunderstorms producing heavy rain. the
thunderstorms may have an impact on the winds on wednesday but a
warm front will try to lift north and enable southwest winds to
increase to near 20 knots, becoming westerly to 25 knots wednesday
night with the passage of a cold front. small craft advisories have
resumed and will likely be needed wednesday night.

a ridge builds east across lake erie on thursday with improving
conditions. another very strong low pressure system will track
through the upper great lakes on friday. a strong low level jet will
be over the lake on friday and could see gale conditions both ahead
of and with the cold front that arrives friday night. the track and
strength of this system will continue to be monitored over the
coming days. the strong southwest to westerly winds could also
result in low water conditions on the western basin of lake erie. a
high pressure ridge quickly builds in on saturday with improving
conditions.

the potential for very large hail, damaging winds and tornadoes,
best chances along and north of us 24 in in and mi.

- potential for heavy rain and localized flash flooding tonight

.evening update...
issued at 757 pm edt tue mar 10 2026

main concern continues to be the threat for severe thunderstorms
overnight, a few of which could produce tornadoes. for that
reason, a tornado watch was issued, for parts of the forecast
area, and is in effect until 200am edt.

high resolution forecast guidance shows temperatures near 70 and
dewpoints in the 60s. this unstable airmass, together with low
level helicity values of 300 to 400 m2/s2 will support rotating
thunderstorms with low cloud bases, and potential for tornadoes
through this evening and into tonight.

a watch means conditions are favorable for tornadoes. the main
takeaway is to make sure you have a way to receive warnings,
especially while you are sleeping, to that you can calmly seek
shelter if needed.

little change in thinking regarding the severe thunderstorm and
heavy rain potential late this afternoon into tonight. as of 18z,
frontal boundary of interest has dropped into far nw in east along
and just north of the mi line. the nose of a developing 40-50 kt low
level jet into this boundary will enhance convergence and helicity
late this afternoon into this evening with discrete supercells
likely expanding east into areas mainly north of the us 24 corridor
during this time. cape/shear profiles appear favorable for sustained
rotating updrafts with large hail and tornadoes the primary threats
initially.

convection likely congeals into more of a linear mode overnight as
stronger upper level forcing overspreads and boundary parallel flow
increases. primary threats likely transition more to damaging winds
with any organized linear segments (possibly a convectively
augmented mcv) and heavy rain/flooding given high moisture content
(pwats > 1.20") and smaller mbe vectors hinting at backbuilding.
opted for a flood watch for mainly urban type flash flooding across
the northern half of the fa where better odds for training
convection exist. the main upper level trough and cold front will
swing through during the day on wednesday with fairly widespread
showers slowly diminishing from west to east. temperatures will also
fall back into the 30s and 40s post-frontal wednesday afternoon
within gusty northwest winds.

high pressure will provide relatively quiet weather conditions in
between systems wednesday night into thursday. a strong mid level
shortwave within the left exit region of a 170 kt upper jet looks to
send a rather robust sfc low (~990 mb) east through wi and northern
lower michigan late thursday night into friday. this system could
bring some brief light precipitation within its waa wing, though the
main impact with be the wind field around this with a period of
advisory level gusts (45 mph+) not out of the question for a time
on friday.

main change was to slow down the onset of precipitation this
evening by a few hours. storms are still expected to increase in
coverage as they spread eastward this evening and overnight.
hail and gusty winds are possible with these storms.

look for thunder to end wednesday morning, with lingering
showers the rest of the taf period. ceilings should lower as
well, and eventually the southerly winds will become west
wednesday morning, and eventually northwest later in the day.

.update...

ongoing upscale convective growth will evolve into a region of
showers and scattered thunderstorms as it tracks across se mi during
the overnight. the cold front has pushed into far northern lenawee
and central monroe counties. while this front may stall or lift a bit
northward overnight with the approaching sfc low, the marine
influence has contributed to a very strong density gradient along
the front which will make it more difficult to be advected too far
northward into se mi. this will keep the risk of surface based
convection (damaging winds and isolated tornadoes) primarily confined
to the far south tonight (likely along or south of line from ann
arbor to monroe). an influx of elevated instability (0-3km mu cape
upwards of 1500 to 2000 j/kg) will pose the risk of large hail with
any thunderstorm tonight across most of the forecast area. overall,
the going forecast looks in good shape. no major forecast updates are
warranted.

a cold front will inch its way across metro detroit early this
evening. a cold moist marine modified airmass on the cool side of
the boundary will support stratus. as low level moisture increases
during the night, ifr and low end mvfr based stratus will increase
in likelihood. upscale convective growth to the west-southwest of
the area will result in clusters of showers and thunderstorms
tracking across the terminals late this evening into the overnight,
most likely during the 03z to 07z time frame. additional upper level
short wave impulses within an approaching sfc low will support
occasional showers, with additional chances for thunderstorms late
tonight into wed morning. sfc temperatures will be around the
freezing mark at mbs. a mention of freezing rain will be maintained
at this airport late this evening into the overnight. strengthening
low level wind fields overnight atop the stable boundary layer will
warrant a mention of low level wind shear.

for dtw...current observational trends and latest model guidance
suggest scattered to numerous thunderstorms advancing across the
airspace in the 03z to 09z time frame. additional rounds of
convection are possible after 09z through wed morning, the
probabilities are lower, leading to reduced forecast confidence.

dtw threshold probabilities...

* high for ceilings at or below 5000 feet through the forecast.

* high for thunderstorms after 03z into early wed morning. low on

20z surface analysis shows a sharpening low level baroclinic zone
slowly migrating southward toward the i-94 corridor. while firm cold
air advection continues north of the boundary, initial attention
focused along and immediately south of the boundary as the frontal
slope engages a gradually destabilizing profile with temperatures now
in the mid 70s in ann arbor/dtw. collective consensus across the
hires solution space indicate roughly 1000-1500 j/kg will exist
across this corridor with a peak in the 21z-00z window. mixed signal
yet on the convective response, acknowledging some lingering
stability concerns atop the boundary layer which may prove limiting
for updraft growth/depth. background deep layer wind field certainly
supportive of greater convective organization should a better updraft
root at the surface, while the frontal zone offers an inherent
focused region of low level shear/srh. window to monitor, but
certainly plausible little to nothing manifests before the boundary
eases further south and pinches off the better low level instability
to the south.

main window for widespread convective activity remains centered
within the 02z to 08z period. convective expansion occurs upstream
this evening as the surface low and subtle height falls work across
the boundary and moisture transport strengthens atop the elevated
frontal zone. inbound activity to remain elevated for nearly all
areas given the depth and strength of low level stability held in low
level east/northeast flow. the i-94 to ohio border corridor will
continue to carry more tenuous positioning with some vulnerability
yet for brief near surface destabilization to remain/materialize if
the surface front wobbles north. there remains a small subset of
solutions that leave that door open. forecast will continue to
highlight associated tornado potential in line with the spc outlook
for this small footprint of southeast michigan tonight. elsewhere,
brief heavy rain and hail potential will exist as deeper theta-e
transport engages sufficient elevated instability residing along the
frontal slope. higher magnitude of cold air advection, with some
influence from onshore flow off the marine waters, will bring
temperatures down into the low to mid 30s across the saginaw valley
and northern thumb regions tonight. this increases the probability
for some areas of freezing rain to materialize where surface temps
flirt with freezing. efficiency of ice accretion may prove limited
given the marginal/warm conditions just off the surface, but
probabilistic data maintains a high probability for a glaze of ice
with around a 25% chance of exceeding .05" in midland/bay city and
bad axe.

surface low migrates through wednesday morning. a weakly unstable
low level environment briefly materializes 12z-18z /mainly southeast/
as pre-frontal southwest flow provides very modest warm/moist air
advection. boundary layer destabilization appears capped at less than
500 j/kg at this stage, but sufficient to maintain a higher
probability for scattered shallow convection. better mid level
dynamics appear to shear northeast within the immediate post-frontal
environment, affording a trend toward drier and more stable
conditions overall by mid-late afternoon. narrow opportunity for some
wet snowflakes mainly north late afternoon and evening within the
south end of the deformation axis. overnight cold air advection will
bring temperatures below freezing all areas by thursday morning.

no significant wx thursday with deep layer stability held under
confluent mid level northwest flow and surface ridging. seasonable
resident thermal profile now entrenched. a highly dynamic mid level
wave projected to eject across the northern great lakes thursday
night and friday. lead wing of isentropic ascent tied to
strengthening elevated warm air advection lifts across the local
area thur night. some variation yet in both moisture quality and
available ascent with southward extent. greatest precip potential
focused friday morning as pronounced height falls collocate with
favorable upper jet support. burst of wet, accumulating snow
plausible mainly across the north assuming a supportively cold
environment. stronger wind potential to accompany the post-frontal
cold air advection friday afternoon/evening, with a notable increase
in wind magnitude captured by improving mixing depth. yet another
mid level wave of north pacific origin forecast to deepen upon
arrival for the weekend period. this system will present another
opportunity for some accumulating snow for portions of southeast
michigan sometime saturday night into sunday. further forecast
revision likely as detail in system trajectory, timing and strength
become more apparent.

deepening low pressure tracks along a cold front that is south of
lake huron at issuance and will lift back north as a warm front
during the day wednesday. the front will act as a trigger for shower
and thunderstorm development this evening, with potential for strong
to severe storms over lake st. clair and lake erie. all severe
hazards remain possible. strong low level jet winds pair with this
system to generate sporadic gale potential overnight, but stability
limits headline issuance at this time. widespread rain and embedded
thunderstorms persist wednesday as the front lifts back north toward
southern lake huron. cyclonic flow around the low transitions to
broader northwest flow wednesday night that introduces 30+ knot gust
potential as cold advection ramps up, albeit brief duration. active
stretch of weather continues for the latter half of the week, with a
return to wintry conditions. increasing confidence in gale potential
for friday as strong low pressure tracks across the great lakes,
alongside wintry precipitation.

widespread showers and thunderstorms will develop tonight and
wednesday as a low pressure system tracks northeastward across lower
