.what has changed...
the wind advisory has been expanded to include the rest of our
southeast counties to account for a brief period of stronger wind
gusts in proximity to the cold frontal passage monday morning. the
remaining wind headlines have been extended through early monday
evening to capture strong southwesterly wind gusts behind the front.
continued refinement has taken place to the snowfall forecast across
the snowbelt for monday night into tuesday.

&&

.key messages...
1) southerly winds will remain gusty at times through early monday.
winds shift southwest and stay strong through the day monday,
gradually easing monday night. showers and possibly an isolated
thunderstorm along a cold front may also briefly enhance wind gusts
late tonight and early monday, mainly across northwest and north
central ohio.

2) wintry weather returns late monday and tuesday with wind chills
dropping into the single digits. accumulating snow is likely in the
primary snowbelt region, with scattered snow showers elsewhere.

3) limited precipitation chances with a gradual warming trend
expected wednesday through saturday.

key message #1...

southerly winds are quickly turning gusty this afternoon as daytime
heating allows mixing to deepen into a strengthening low-level jet
overhead. a wind advisory has kicked in for much of the area, with a
high wind warning for erie county pa. a couple of 50kt/58 mph gusts
are possible in northwest ohio through late this afternoon as has
been observed to our southwest, though think this would be on a
brief and localized basis so am holding with the advisory there.

a very strong low-level jet (65-75kt at 850mb, 40-55kt at 925mb)
will remain in place through early monday ahead of an approaching
cold front. the overall strongest winds in this regime will occur in
erie county pa this evening through pre-dawn monday, where
downsloping will bring potential for some gusts over warning
criteria of 50kt/58 mph, particularly across the northwestern third
of the county between the ridge tops and lakeshore. some downsloping
will occur close to the northeast oh lakeshore as far west as the
cleveland area, though to a somewhat lesser magnitude with
occasional advisory-level (40-49kt or 46-57 mph) gusts favored in
this area. elsewhere, wind gusts will likely lull at times overnight
in the overall warm advection regime as the near-surface cools and
stabilizes a bit, though it will remain gusty at times.

we`ll likely see some uptick in wind gusts from west to east late
tonight into early monday as the front progresses through. a
marginal risk for severe weather (level 1 of 5) remains in place
west of the i-77 corridor for overnight tonight. while there`s good
agreement at this point that meager (<100 j/kg of sbcape) will be in
place across the local area with convection expected to be weakening
as it comes in, a lack of a stronger near-surface inversion and
strong linear forcing along the front may allow a somewhat
organized, low-topped qlcs to push into the western half of our area
before completely weakening. if this pans out, any more formidable
line segments could locally enhance winds to severe limits (50kt/58
mph or greater) and bring potential for tree/power-line damage. it`s
worth noting that given the meager instability, any severe weather
may occur in the absence of lightning. confidence in severe weather
remains low to medium, and feel the marginal risk for damaging winds
covers it well. even without convection, the quick pressure
rise/couplet with the front and vertical motion associated with the
cold front itself may also help force stronger wind gusts, perhaps
back into advisory range, to the ground in proximity to the frontal
passage. confidence in advisory-level non-convective winds occurring
with the frontal passage is not high, especially in our southeastern
counties, though did expand the wind advisory to include the entire
forecast area to be in collaboration with surrounding wfos.

behind the cold front, strong cold advection along with a decent
pressure gradient and quick pressure rises will support continued
gusty southwest winds on monday. flow aloft appears marginally
strong enough to support some advisory-level gusts, especially west
of the i-71 corridor and along the lakeshore. have gone ahead and
extended most of the wind headlines through early monday evening,
save for our far southeastern counties. one more extension may be
needed along the eastern lakeshore into monday night, though will
allow future shifts to better evaluate that possibility.

outside of a passing shower late this evening or tonight, we will
remain dry and warm until the cold front brings a relatively narrow
band of rain to the area late tonight into monday morning. overall
rain amounts remain modest and have perhaps trended a bit lower,
generally in a 0.10-0.40" range.

key message #2...

it will remain very warm/mild until the cold front crosses very late
tonight or monday morning, with many areas staying in the upper 50s
or lower 60s until the front crosses. temperatures will then quickly
fall on monday, dipping below freezing from west to east during the
late afternoon and early evening. by early tuesday, air temperatures
will bottom out between the upper 10s and lower 20s with wind chills
dipping into the single digits. while not overly hazardous on its
own, this will be quite jarring after recent (and ongoing as of this
writing!) temperatures in the 70s and could affect outdoor st
patrick`s day plans. highs on tuesday will mostly stay in the 20s,
with another night tuesday night where large portions of the area
will see air temperatures reach the 10s for lows.

with the cold comes snow potential. while the greatest potential for
inches of accumulation will reside in parts of the snowbelt, much of
the area stands to see at least a bit of the white stuff. the band
of rain along the front will slow before exiting our eastern counties
monday afternoon, in response to the base of the incoming upper
trough taking on a more neutral to negative tilt. this will allow the
cold air to catch it enough that our far eastern counties may see a
brief period of wet synoptic snow later monday afternoon/early
evening. warm ground and marginal air temperatures should preclude
any roadway impacts before sunset, though some locations may see some
slushy/grassy accumulations from the synoptic snow from far eastern
ohio into northwest pa. otherwise, scattered snow showers are likely
area-wide beneath the upper level trough with some moisture
connection to lake michigan, particularly late monday afternoon into
the first half of monday night as a sharp low-mid level trough axis
swings through. the synoptic lift with the trough passage, weak low-
level instability, and gusty background winds may allow snow showers
late monday afternoon or evening to be a bit "squally". as
temperatures quickly plunge well below freezing into monday evening,
slick spots can develop on roads across the area where more
organized/intense snow showers occur.

shifting into the snowbelt, we are still looking at a brief window
monday night into tuesday morning where conditions appear conducive
for some late-season lake effect snow. expect lake effect snow to
begin developing and pushing onshore late monday evening as winds
align out of a west to slightly north of due west direction behind
the passage of a low-mid level trough axis, with this general flow
persisting until tuesday afternoon when low-level ridging starts
pushing in and backing the flow more southwesterly.

there is about a 15 hour window window starting around 8 pm monday
in which moderate lake-induced instability, good moisture/lift in the
preferred dendritic growth zone, limited wind shear, multiple
upstream lake moisture connections, and good convergence along the
lakeshore near or just east of cleveland will support moderate to
heavy snow (peak rates around 1" per hour) within more organized lake
effect snow bands. the main limiting factor is strong boundary layer
winds over the lake (gale or near gale-force) until early tuesday,
which may impact band organization or at the least push snow farther
inland. the secondary limiting factor is the time of year, with a
strong negative diurnal influence on lake effect processes during the
afternoon hours, limiting the window during which good accumulations
can occur. ultimately, continued to refine the snowfall forecast as
higher resolution guidance comes into range and have a general 2 to
5" snowfall forecast across the primary snowbelt. the higher amounts
will likely be found in the higher terrain away from the lakeshore,
with most of the snow falling monday night into tuesday morning but
with some lighter snow continuing into tuesday night along the
lakeshore. advisories may be needed for the snow, especially keeping
in mind that snow/impacts may peak during the tuesday am commute.

key message #3:

the late taste of winter will be short-lived, with highs returning to
the 50s thursday into friday and even some 60s becoming possible into
the weekend. minor precipitation chances are in the forecast for
parts of the area on wednesday, thursday, and later friday into
friday night. the precipitation on wednesday may fall in the form of
snow, though confidence in measurable precip is low as the system
will be weakening as it comes in...with any snow not expected to be
impactful during the daytime hours in mid-march.

.aviation /00z monday through friday/...
awaiting a cold front to track through the region after 05z with
a convective line of showers that will likely enhance the
already robust wind gusts that are currently 30-40kts. tol/fdy
has the best chance for tsra, but will only mention this as
vcts/cb as the coverage of thunder with the line looks to wane
as it approaches the in/oh state line due to lack of convective
instability. winds in the wake of the cold front will be just as
strong, 35-45kts, and wind directions turning from se/s to more
sw. ceilings lower to mvfr behind the cold front as well.
strong cold air advection brings snow showers into play late in
the taf period at yng/eri.

outlook...non-vfr will likely persist with scattered rain
showers changing to scattered snow showers on monday. lake
effect snow showers and possible squalls will impact the
snowbelt of neoh and nwpa monday night into tuesday.

.marine...
marine weather conditions are expected to be very rough today
through tuesday. a small craft advisory is currently in effect
today into tonight. a gale warning will take in effect for all
of lake erie monday morning through tuesday morning. southerly
winds will increase 25 to 30 knots today and tonight.
southwester to westerly gales 35 to 40 knots will move over lake
erie monday through tuesday morning. gusts monday will be up to
50 knots likely. waves will be increase with the highest over
the open basin up to 15 feet or more. winds will slowly ease
down tuesday into tuesday night but remain from the west 15 to
25 knots. additional sca will likely be needed after the gale
warning. winds and waves will be on the lighter side mid to end
of next week, southerly around 10 knots

as the strong winds shift southwesterly to westerly behind the
strong cold front monday morning, water levels will likely drop
in the western basin of lake erie. a low water advisory has
been issued monday morning through tuesday morning as water
levels are expected to drop below the critical mark for safe
marine navigation.

little change in thinking into tonight through tuesday morning as a
major early spring storm system tracks through the region. as of
17z, a ~993 mb sfc low was analyzed near the ia/il border. this
feature will continue to deepen east-northeast as its mid level
shortwave takes on a negative tilt and eventually closes off a deep
tropospheric low center north through the western and northern great
lakes tonight into monday.

system warm sector continues to build north this afternoon with
strong southerly winds and temperatures surging well into the 60s to
near 70 for most locations. weakening showers will clip far nw
in and sw mi this afternoon, with most remaining dry with high
end advisory level wind gusts (up to 55 mph) anticipated at
times.

a more organized line of gusty showers and perhaps a few
thunderstorms remains on target to slide east through the area this
evening into the early overnight along an incoming strong cold
front. the strength of the low level wind field with 850 mb
magnitude up around 70 knots does continue to support spc`s slight
risk for iso-sct damaging winds with more robust low topped
convective elements. the potential saving grace this go around is
the overall dearth of instability this far north with models still
only in the low-mid 50s for sfc dewpoints pooled along the front.
may very well just end up just behind a line of showers with gusts
40-50 mph.

blustery and sharply colder air wraps in under what should be a ~980
mb low into northern michigan late tonight into monday. wind whipped
snow showers should also be flying later monday morning through
monday evening cwa-wide as low level lapse steepen under the
eastward advancing deformation/upper trough axis. expect minor
accums and brief vis reductions outside of our les belts during this
time. no changes to the winter weather advisory for our northwest
flow les belts monday into tuesday morning from a combination of 2-
5" of accumulating snow, temps well below freezing, and gusty winds
helping to create reduced visbys and blowing snow. wind chills are
the story otherwise into monday night and tuesday, around zero
degrees fahrenheit.

ensemble and deterministic model solutions continue to point to late
tuesday night into wednesday morning for the next opportunity for
light snow as a clipper system drops through in northwest flow. the
flow pattern then looks to flatten out a bit thereafter supporting a
warming trend for the second half of the week.

vfr conditions for the first few hours with strong
south/southeast winds ahead of an approaching cold front. a few
rain showers are possible ahead of this front, as well as some
turbulence / low level wind shear.

starting around 02z, confidence in thunder increases as the cold
front approaches, so did add a tempo for tsra and ifr
conditions. once the front passes through, winds will become
more westerly and expect mvfr/ifr ceilings near 1000 ft. this
will last through the overnight hours.

on monday, winds will become more northwest, and should have
snow showers throughout the day. toward the afternoon,
confidence increasing in some heavier bands of snow, so did add
a prob30 for lower visibility.

a strong warm front now over kfnt will lift north toward kmbs this
evening, driven by rapidly intensifying low pressure forecast to
move from illinois this evening to central lower mi by monday
morning. warm sector mixing will support wind gusts over 40 knots at
times this evening. upstream warm conveyor convection will rotate
across se mi between 04z and 08z. some decrease in the instability
forecast may result in some slight weakening. given the strength of
the upper wave rotating in from the west, the intensity of the large
scale ascent will be enough to justify a mention of thunderstorms at
all terminals. although there may be some fluctuations in wind
speeds within the broad region of showers overnight, the intensity
of the wind fields will justify leaning on the strong end of
guidance, with continued gusts over 30 knots. the associated cold
front will rotate across se mi between 10z and 12z, marked by a wind
shift to the sw. deepening mixing and continued strong wind fields
will support wind gusts near 40 knots through the day monday.

for dtw...a scattered to broken line of thunderstorms is forecast to
move from east to west across the airspace between 04z and 09z.
there may be some weakening of the convection as it moves across the

the wind advisory is expanded across all of se mi and extended
through monday evening with this afternoon`s forecast update.
satellite and surface observations so far today are tracking the
well-mixed warm sector from the ohio valley into lower mi this
afternoon and evening. peak gusts in the 40 to 50 mph range have
been prevalent across il/in and reached the ohio border stations as
of 3 pm. similar gust conditions are expected to push farther north
into se mi during late afternoon and evening. the northward
elongation of the deepening low pressure center is the key in this
case to overcome the customary influence of the eastern great lakes
to delay northward progress of the warm front, although it still has
a stabilizing influence closer to the shorelines and with northward
extent. advisory level gusts become more intermittent after sunset
as model soundings indicate some perishable boundary layer
stability. gust frequency increases again after midnight as thermal
profiles become more neutral, as the low level jet peaks overhead,
and as showers increase across the area. this is followed by a wind
surge with the cold front and then hazardous gusts that continue
through monday as cold air surges into the region and the primary
surface low drops to near 980 mb depth in northern lower mi monday
afternoon.

showers become widespread across the area during the evening with
isolated to scattered stronger thunderstorms still to evaluate going
through the night. taking cues from afternoon observations and
hourly mesoanalysis shows a few lightning strikes now in far sw
lower mi feeding into deeper convection along the cold front
trailing off into the mid ms valley. mucape is still sub 500 j/kg at
mid afternoon which is captured well by the 12z href that shows the
surface based instability axis moving into and then collapsing over
southern lower mi. various hi-res models seem to acknowledge the
instability trends with solutions that show convection in a more
organized linear mode to the west and south this afternoon tending
to become more cellular to the north into lower mi while maintaining
some structure toward the ohio valley. the wind profile remains
worthy of respect for any surface based cell that can survive the
shear, and a marginal risk for severe intensity remains in place for
the area until the cold front sweeps through toward sunrise monday
morning.

monday carries a return to winter for the great lakes as cold air
surges into the region. the wind advisory highlights 45 to 50 mph
wind gusts, however the parent low pressure system is increasingly
supportive of lake enhanced snow showers/squalls during the
afternoon into monday evening. model soundings indicate convective
depth approaching 10 kft by mid afternoon aided by the 500 mb trough
and cold core reaching down to near -35 c. mid march daytime heating
also contributes to the steep lapse rate below cloud base and the
strong wind field adds a component to the snow squall equation while
direction shifts sw to nw by evening. the forecast is leaned toward
greater coverage making it into se mi from the lake michigan
shoreline, and a localized quick inch of accumulation is in reach
where any location gets more than one snow shower.

cold air is then rooted in the great lakes for the mid week period
highlighted by wind chill around zero tuesday morning. the next
round of snow still looks light in mid week model data and marks the
beginning of a late week warming trend.

marine...

an anomalously strong low pressure system will travel from southern
lake michigan late this evening, strengthening as it moves in across
northern lake huron by tomorrow morning and afternoon. this will
bring a wide array of unsettled conditions, including extended
windows for gust to gales, rain showers, snow showers, and highly
localized freezing rain/sleet chances.

for this afternoon... a warm front and associated strong low-level
jet now over southern michigan will continue to push north, stalling
around north-central lake huron by this evening. stability has
quickly increased across the southern great lakes with the advent of
warmer temperatures which hold gust potential to below gales. the
exception remains across north and north central lake huron as a
more neutral thermal profiles have allowed for strong winds aloft to
mix down.

for this evening... the approaching low pressure system will rapidly
increase the strength of the pressure gradient over the eastern
great lakes. the strength of the pressure gradient alone will likely
still support elevated gusts around 25 to 30 knots despite southern
locations being in the warm sector. for locations north across north-
central and northern lake huron, a lull in gust to gales will be
possible favored in the late evening and early morning hours monday
as the center of the low arrives overhead. in this window, freezing
rain to sleet will be possible across northern lake huron, with rain
and some isolated thunderstorm chances holding for locations south.

as the low departs the region late tomorrow into tuesday morning, a
strong cold front delivering arctic air arrives over the great
lakes. this will produce a well mixed environment and will bring the
most favorable conditions to see gust to gales for all locations,
down through lake st. clair and lake erie. the intrusion of cold air
will also convert any rain showers back over to snow showers and
will bring the likely chance for heavy freezing spray. a heavy
freezing spray warning has been issued for all of lake huron.
additionally, isolated squalls will be possible monday afternoon and
evening, favored across the southern lake huron basin, lake st.
clair, and lake erie. gale potential lasts through at least tuesday
morning before a brief ridge of high pressure fills in by tuesday
afternoon, ending gales. gale warnings are in effect for all marine
zones.
