.what has changed...
overall, no major changes needed with this forecast. there are
some concerns of decaying convection moving into the area
tonight, although confidence remains low at this point.

&&

.key messages...
1) unsettled weather likely as early as tonight and on tuesday
afternoon into tuesday night. some storms may be strong to
severe late tuesday into tuesday night.

2) an active weather pattern will present multiple chances for
rain and thunderstorms for mid to late week.

3) above average temperatures are expected to persist for the
next several days.

key message 1...
unsettled weather is expected through late tuesday. there`s
some potential for isolated strong storms tonight, although a
greater risk exists for tuesday afternoon into tuesday night.

warm/moist southwest flow is expected across the area over the
next couple of days as a warm front continues to lift away from
the cwa and settles over the upper midwest/great lakes.
scattered/periodic light rain showers are likely across the area
through the daytime hours today. it will also be quite gusty
with southwest wind gusts to 25 to 35 mph likely this morning
through this afternoon. by this evening, a weakening complex of
storms may approach from the west or northwest, although there
is very low confidence in the timing, placement, and coverage of
convection due to weak forcing and uncertainty in instability
this far southeast. the best coverage of showers/storms will be
closer to a frontal boundary to the north/northwest of the cwa.
nonetheless, if storms do manage to move into the area
overnight, elevated instability and a llj over the region
support low-end threat of some isolated gusty winds and hail,
primarily across nw oh which is clipped by a marginal risk
(level 1 of 5) of severe weather.

attention then turns to tuesday afternoon into tuesday night as
somewhat better upper level support arrives from the west in
response to a deepening trough over the plains. the local area
will remain in the warm sector throughout the day tuesday and
expect mlcape values of 1500 to as high as 2500 j/kg across
much of the area with a strong llj will moving into the region
late in the day and into the night. effective bulk shear and 0-6
km shear values will reach about 30 to 40 knots in the northern
half of the area as better winds aloft move into the region
tuesday evening, which would support a line or broken line of
strong thunderstorms. all hazards will be on the table, although
damaging winds and large hail will be the primary concerns.
there is a slight risk (level 2 of 5) for severe weather across
northern ohio with a marginal risk (level 1 of 5) across the
remainder of the cwa. there are several limiting factors that
could throw a wrench into things, however. first, any scattered
showers or storms early in the day or convective debris from
monday night showers/storms could keep clouds around and limit
destabilization. second, forcing will be somewhat weak with the
best forcing to the north of the local area. third, a capping
inversion will likely be in place and this will need to be
broken for any stronger convection to develop. and fourth, the
evening/night timing of convection would be diurnally
unfavorable, resulting in a more stable atmosphere (or perhaps
more elevated instability) by the time convection moves into
the cwa. long story short, there`s high confidence in scattered
showers and thunderstorms tuesday into tuesday night, although
confidence in the timing and likelihood of severe weather is
quite low at this point and will likely rely on mesoscale
features that have not yet been resolved.

key message 2...
periodic showers and thunderstorms will continue throughout the
majority of the week as a frontal boundary wavers over the
upper great lakes and upper midwest and the local area remains
in the warm sector. the timing of any showers/storms will rely
on the timing of weak disturbances that ripple across the
frontal boundary, but as of now it appears that pops will peak
on wednesday as low pressure lifts northeast into the upper
midwest. confidence in any stronger convection is low at the
moment. precipitable water values will be unseasonably high at
1.2 to 1.5 inches wednesday into thursday and there may be a
brief period with a swath of higher pwats across the northern
part of the area on wednesday. this could result in periods of
moderate to heavy rainfall rates in showers/storms which could
lead to isolated instances of flooding and rises on the most
responsive creeks and streams. fortunately, the recent stretch
of drier weather has allowed antecedent conditions to trend a
bit drier, which will help mitigate the onset of flooding unless
repeated rounds of heavy rain move over the same
locations/basins. a brief period of drier weather is likely as
the aforementioned frontal boundary finally pushes south of the
area, but rain chances will quickly return as the next system
approaches from the west late friday into saturday.

key message 3...
persistent warm air advection will result in temperatures that
are well above normal through the first half of the weekend.
widespread highs in the 70s are expected through saturday with
periods of lower 80s likely across portions of the area. lows
will also be well above normal in the 50s and 60s. for
reference, average high temperatures for this time of year are
generally in the upper 50s and lower 60s.

.aviation /06z monday through friday/...
gusty southwest winds continue across terminals overnight into
monday afternoon. have maintained brief mention of llws at all
taf sites through 08-12z/mon as a southwesterly llj of 45-50
knots remains overhead. gusts will become more frequent across
terminals this morning and afternoon with gusts of 25-30 knots
common across the region. winds and gusts will gradually
diminish while turning southerly late tonight.

light and scattered rain showers are expected to push east
across terminals through today. visibilities look to remain 6sm
or higher. can`t rule out brief visibility reductions to mvfr
in moderate showers. ceilings will likely fall to mvfr across
western and central taf sites (tol/fdy/mfd/cle).

the combination of a mid level short wave and broad advective
forcing has sustained rain showers from west to east across the
area this morning. despite the decent moisture transport this
morning, the strength of the low level thermal ridge has allowed
for large enough low level dew point depressions to provide
some enhancement to surface wind gusts in association with
these showers. fairly strong background flow (~40 knots in
lowest gate of kiwx vwp data) has also mixed down fairly
efficiently with these showers with some instances of 40-50 mph
wind gusts. this potential should gradually wane over next few
hours. higher res guidance does indicate some renewed convective
development on southern periphery of departing mid level wave,
and where secondary low level theta-e ridge starts to nose into
north central in next few hours. this could yield a cluster of
showers with perhaps embedded thunderstorms across northern
in/northwest oh early this morning through daybreak.

additional showers and storms are possible today, and the storm
prediction center has continued a marginal risk of severe storms for
most of the forecast area. some lull in scattered/showers storms is
expected by mid morning, but will need to watch for possibility of
weak mid level wave across kansas as it reaches the western great
lakes this evening. a renewed surge of stronger low level theta-e
advection is expected to accompany this short wave with
strongest advective forcing expected across northeast il. the
approach of this central plains wave will also mark the leading
edge of stronger mid level lapse rates. while synoptic forcing
does not appear strong today, destabilizing trends in
thermodynamic environment with the steeper mid level lapse rates
and the presence of the more distinct low/mid level theta-e
boundary could provide a focus for at least an isolated severe
threat late this afternoon into this evening. while greatest
threat for isolated severe today may be north of us 30 as mid
level speed max shifts across southern great lakes, hard to
discount any location across forecast area given theta-e
boundary will likely be hanging back a bit more to the south
from northeast illinois into the local area. mlcapes on the
order of 1500-2000 j/kg, modest deep layer shear of 30 to 40
knots, and steep low level lapse rates could pose some threat of
isolated damaging wind gusts in addition to large hail threat
with steep mid level lapse rates. some lull in thunder chances
is expected early overnight, but may need to watch for
possibility of remnants of stronger great lakes convection to
propagate southward to the southern great lakes toward daybreak
tuesday. these storms could have some strong wind gusts
persisting early tuesday morning but confidence in this
evolution is low.

tuesday/tuesday night still appears to be the period of greatest
concern for scattered severe storms and most of the forecast
area remains in an spc day 2 slight risk for severe storms. the
forecast challenge for this event remains on convective
initiation portion of the event. stronger mid/upper level
forcing will likely be hanging back to the west across the
rockies as primary upper level wave begins to shear eastward.
best forcing mechanisms for convective initiation will be at
nose of stronger low level flow and strong low level moisture
convergence across nw il/sw wi/ne ia. will need to see if there
is any remnant leftover boundary from early tuesday great lakes
convection that help overcome some surface based cin for more of
an isolated storm development locally during the early/mid
afternoon hours. the expectation is still that discrete storm
development across mid ms rvr valley should tend to congeal
across western/southern great lakes later evening tuesday with
strong component of shear parallel to the boundary. greatest
potential severe risks still appear to be large hail 1-2" in
diameter given very steep mid level lapse rates and damaging
wind gusts, with greatest potential of hail across the northwest
which could be involved in the earlier stages of the event mid-
late evening. some potential of heavy rainfall will also have
to be monitored as outflow emanating from this convection may
become parallel to environmental shear. a strengthening
southwest llj south feeding into these potential storms/outflow
should also weaken upwind propagation vectors yielding potential
of training convection.

wednesday`s severe potential will be conditional on convective
evolution tuesday night, and if more mature convective system can
develop tuesday night an effective boundary may get pushed across
southern half of the forecast area during the day. instability
magnitudes should be more questionable on wednesday and stronger
synoptic forcing will still likely be lagging back to the west. some
isolated severe potential may evolve (mainly wind), but confidence
is lower in comparison to late tuesday.

the primary upper level wave will finally top the ridge across the
great lakes on thursday, but slow evolution of this feature will
keep thunder chances going into thursday. some indications in
guidance that better kinematic fields on thursday could be eastward
displaced from better instability hanging back to the
west/southwest, so any organized severe threat appears to be low at
this time.

after brief low level caa late thursday, quick rebound of mid level
heights and rapid onset of low level waa will keep the much above
normal temps going through friday (highs possibly back near 80 by
friday). no significant changes made to temp forecast through
friday, with confidence in continued much above normal temperatures
and daily highs in the 70s. medium range guidance continues to
struggle with ensemble/deterministic consensus on timing
frontal passage with next stronger longwave trough next weekend,
but an overall trend to least a brief shot of cooler
temperatures still appears on track for late weekend/early next
week, along with a potential of more showers/storms first half
of weekend with cold frontal passage.

a mid level short wave tracking across the southern great lakes
and associated broad warm/moist advection has been enough to
sustain showers into most of northern indiana early this
morning. the quality of low level moisture return to this point
has been modest and relatively dry subcloud layer combined with
strong background winds have contributed to pockets of 40 to 50
mph in association with the showers. this threat appears to be
waning over the next few hours with peak gusts likely to settle
into the 30 to 40 mph range for a few hours before diminishing
further. higher resolution near term guidance does depict some
signal for some scattered convection to develop along interface
of stronger upstream theta-e gradient as it pushes east through
daybreak, and have maintained the prob30 tsra mention at kfwa
from 09z to 12z.

through the remainder of the period, the concern will be on
convective potential. a more pronounced surge of higher low
level theta-e air is expected to lift northeast from west
central illinois. isolated storms could develop along this
theta-e boundary with present indications suggesting best
chance ne il into nw in. this zone of possible storm development
today will also mark an uptick in mid level lapse rates which
could enhanced strength of any isolated convection and possibly
allow some tendency to upscale growth or a small convective
cluster. confidence in this scenario is low however as
identification of any clear upstream short wave is difficult. a
weak mid level perturbation across central ks could be a feature
to watch as it approaches the western great lakes region later
this afternoon/early evening. did include a prob30 tsra group at
ksbn late afternoon/early evening to account for this
potential.

areas of rain showers will depart east of the terminals around or
before 12z, marked by the departure of an upper level short wave.
subsidence in the wake of this wave will result in a deep inversion,
with model guidance suggesting a rapidly expanding mvfr based
stratus deck impacting the region in its wake as low level moisture
advects under this inversion. daytime heating will slowly lift the
inversion base and will result in a subsequent lifting of ceiling
heights during the afternoon. this will lead to increasing
probabilities for vfr based ceilings, especially after 18z.
thunderstorm chances will increase tonight as conditions will be
favorable for upstream convection to move across southern michigan.

dtw/d21 convection... there is increased chances for clusters of
thunderstorms to move across the metro airspace tonight, mainly
after 00z. timing remains highly uncertain at this time.

longwave trough over the west coast and ridging over the se conus
continue to remain firmly in place to start the week keeping the
central conus up into the midwest/great lakes in a pattern of deep
layer southwesterly flow. this will result in warmer than normal
temperatures with highs mainly in the 70s (outside of locations
along lake huron shoreline), gusty daytime winds, daily rain
chances, strong to severe storms at times, and a risk of flooding.
while consistency in the longwave pattern adds some confidence to
the forecast this week, inconsistencies in the short range models
resolving mesoscale features (like potential upstream mcs
development) still leaves questions about precip timing and qpf
placement. convective nature to most of the precip also brings into
question model qpf output which likely will fall on the low side
where the storms line up.

helping to dictate placement of showers and storms will be a warm
front extending eastward from a surface low setting up over the
central/northern plains. the front will largely be positioned over
northern mi with typical fluctuations due to convective complexes.
this paints central and northern mi with the highest qpf and highest
confidence of these periods of rain/storms as the mid level waves
pass over that region as well. farther south over most of se mi,
we`ll have waves of storms pass over with periods of dry in between.
i`ll highlight higher confidence time windows tied to mid level
features, but there will be likely be convective complexes that will
be handled with shorter fused forecast updates.

for today, spc has all of lower mi in a marginal risk for severe
storms. early morning rain should be ending soon after sunrise this
morning with warm and dry conditions most of the day. there are 2
windows for potential showers/storms mainly later this evening and
tonight. first from 23-03z as the potential convection firing over
eastern iowa rides the elevated instability gradient into southern
mi. the canadian hires models are most bullish with bringing
widespread stronger convection across the area. most of the rest of
the model suite advertises more scattered activity but something to
watch none-the-less. spc outlook likely more for the later round of
storms as a surface low riding the warm front with the nose of the
next stronger llj after 05z. strong mid level lapse rates and mucape
up around 1000 j/kg for both events with strong capping from waa so
elevated storms would be most likely with a hail threat, but there
is a wind threat as well.

by tuesday the longwave trough will have crossed the rockies which
will continue eastward passing through the great lakes late
thursday. several more shortwaves will pass through the region
during this time. things are continuing to look like tuesday evening
could get quiet active locally though as the overnight low crossing
northern mi strengthens the front stalled across mid mi while the
next strong llj around 50 knots surges into the region. cape will
rise greater than 2000 j/kg with models soundings showing the
instability become surface based. very strong lapse rates will be
present with strong shear. timing looks most likely after 00z but
carrying through much of the night with an west-east orientation
allowing for training storms. some models are targeting mid mi for
the highest qpf while others suggest earlier convection will push an
outflow boundary down to near m59 which will have additional storms
focusing down there. spc day2 outlook has most of lower mi in a
slight risk designation with all hazards possible. in addition to
the severe chances, we are in a ero marginal risk so rainfall
amounts will need to be monitored.

storm chances continue wed and thurs as the main upper level trough
passes over the region. friday into saturday looks dry as shortwave
ridging builds overhead but the next longwave trough is already
working across the conus and will bring storm chances back to the
forecast saturday and sunday. strong cold front looks to pass
through the region sunday dropping highs back into the 50s with lows
in the 30s.

small craft advisories remain in effect this morning for the
southern lake huron nearshores, in addition to lake st. clair and
western lake erie. waves are responding to stronger gradient winds,
in excess of 20 knots. a few gusts to gales remain possible early
this morning until a 65+ knot low-level jet axis exits the central
great lakes. the main area of concern amidst the constricted
southwest flow remains saginaw bay, funneling/converging off-shore,
but also near the straits. conditions quickly improve this evening
after shortwave ridging moves in. several additional rounds of
showers and thunderstorms are likely throughout the week due to a
series of troughs, low pressure systems, and fronts.
