key message 1...
high pressure that is over the region today will push eastward
tonight. an upper level trough will move into the upper great
lakes region on wednesday. a cold front will push through the
great lakes and into the upper ohio valley late wednesday.
surface dewpoints will climb into the lower 70s by wednesday
afternoon. high temperatures will reach the middle to upper 80s
on wednesday. 0-6km shear will increase to 40 to 45 knots and modest
instability will develop of 1000-2000 j/kg ahead of the cold front
late wednesday. there is a slight risk (level 2 of 5) for severe
storms ahead of the cold front with the main threat being isolated
damaging wind gusts. pw values will increase to around 2 inches
which will support heavy downpours and localized heavy rainfall
possible. the time window for possible severe weather will be
between 4 pm and 10 pm. the cold front will slow down as it moves
into central ohio wednesday night. another weak area of low pressure
will ride along the frontal boundary late wednesday night into
thursday with another round of rain likely, especially for areas
south of highway 30. the front and rain chances will finally clear
out of the area by thursday evening.


key message 2...
high pressure will build in over the great lakes and the upper
ohio valley friday and saturday. high temperatures will be in
the middle to upper 70s on friday and lower to middle 80s by
saturday. a weak cold front will try to move through the great
lakes region late sunday but stall out just north of our area.
warm and humid weather will continue into early next week.

the main message for aviation weather will be vfr conditions
until 21z wednesday at most tafs for this update. south to
southwest of 5 to 10 knots through 15z wednesday. southwest
winds will increase slightly for mfd, cle, cak, and eri late
wednesday morning and midday between 10 to 15 knots with gusts
around 20 knots by 18z. sustained southwest to west of 12 to 15
knots with gusts up to 25 knots from 18z wednesday to 00z
thursday.

convection is expected to near and around all taf sites with a
tempo group for tsra start around 20z for taf sites
ktol...kcle...kcak and eri. will insert prob30 group for tsra
after 22z wed for taf sites away from the lake...kfdy...kmfd and
kyng. mvfr to ifr conditions can be expected all taf sites
around 00z thursday due visibility restrictions in rain/mist and
lowered ceilings.

outlook...storms will diminish from north to south from 06z to
12z thursday. mvfr condition to lowered ceiling will lift
wednesday night to thursday morning.

.marine...
there will be a brief window for a lake breeze this afternoon
with a east-northeast wind 5 to 10 knots and a light chop of
waves around a foot. southerly winds will increase to 10 to 15
knots tonight, becoming west-southwesterly ahead of a cold
front on wednesday 15 to 20 kts. marine zones offshore of
cleveland and eastward will see wave of 3 to 4 feet. a small
craft advisory may be needed for wednesday. a broken line of
storms are expected ahead of the cold front late wednesday.
winds northwesterly 10 to 15 knots are expected in the wake of
the cold front wednesday night through thursday night with wave
heights 1 to 3 feet. high pressure will build over the lake on
friday with light northeast winds 5 to 10 knots and waves of 1
to 2 feet.

- a warm and more humid airmass will be in place into early
thursday. cloud cover and precipitation may cause large
variations in temperatures wednesday.

- there is a 40% to 60% chance of showers and thunderstorms
wednesday through early thursday morning.

- breaking waves and currents are expected at southeast lake
michigan beaches on thursday.

- somewhat cooler and less humid friday into monday.

low confidence forecast remains through thursday as models
continue to differ on finer details for temps and precip
chances, especially wednesday night. main cold front (much
cooler and less humid air) is located from minnesota to central
ne and is not expected to arrive till thursday. much of our
weather will hinge on pre-frontal troughs, leftover outflow
boundaries and subtle waves resulting in a lot of challenges on
coverage, timing and intensity.

area of showers and storms has persisted from central ia into
much of wi with only a slow eastward trend. cams vary on what
will be left of this area as it enters towards 12z wed.
regardless of what shape it starts, generally expected some
widely sct to sct showers and maybe a few storms to persist in a
somewhat unstable atmosphere. the marginal severe threat keys
in on the afternoon and evening hours when pockets of clearing
could allow for some increased instability to produce some gusty
storms. overall shear is lacking and lapse rates are rather
unimpressive so any gusts appear to be isolated at most. even
larger challenges exist where the best instability axis and
lingering boundaries setup wednesday night into early thursday.
overall trend has been moreso into central in resulting in a
continued southward trend to higher pops. wasn`t ready to
completely eliminate pops but did blend with previous forecast
to nudge down.

eventually the main front will arrive thursday into thursday
night and usher in an end to any precip and much more
comfortable conditions. the battle will then continue between
the sprawling upper ridge across the se states and another
deeper trough that will attempt to move in next week. for the
time being, no major swings in temperatures or high precip
chances.

primarily vfr with light southerly winds giving way to
southwesterly winds up to near 10 knots on wednesday. scattered
showers and low chances for an embedded storm do enter the
forecast along a pre-frontal trough, best chances (20-40%)
later tonight into wednesday morning at ksbn, and at kfwa
wednesday afternoon. brief vis restrictions will be possible in
heavier showers, though point chances remain low at this point
given weak forcing and unfavorable diurnal timing.

returns for thursday and friday.

vfr conditions hold through tonight, as a steady increase in mid
level moisture commences downstream of an approaching frontal
boundary. this moistening will lead to some intervals of light
shower production during the early-mid morning hours, particularly
from ptk northward. potential for additional shower development
throughout wednesday as the frontal boundary eases across the area.
this may offer some intervals of mvfr conditions - higher
probability again from ptk northward. an isolated thunderstorm will
be possible, but confidence in occurrence remains too low to mention
attm. prevailing wind from the southwest wednesday will turning
modest gusty into the 20 knot range.

d21/dtw convection...thunderstorms are not forecast through tonight.
low potential for thunderstorm activity wednesday afternoon.

.dtw threshold probabilities...

* low for ceiling 5000 ft or less wednesday afternoon.

* low for thunderstorms on wednesday.

an upper level ridge axis (~591 dam at 500 mb) slides east through
the central great lakes this evening. height falls tonight/tomorrow
as a shortwave trough tracking through montana this afternoon moves
through lake superior. a moisture axis (pw values around 2 inches)
over the midwest to fold over/northeast into southern lower michigan
wednesday morning, with a cold front slowly tracking through
southeast michigan during the day. showers are likely, but clouds
and earlier timing likely limit instability, supporting only a
chance of thunderstorms. the far southeast section of the cwa (adg-
dtw-phn) stands the best chance of building up enough instability to
draw some concern for strong thunderstorms, as wind fields are
elevated (40 knots 850 mb). as such, gradient winds during the day
will increase ahead of the cold front, and local probabilistic
guidance suggesting wind gusts 25-30 mph. machine learning also
indicating a 2-5% percent chance of damaging winds over southern
monroe county, in line with the spc day 2 outlook. any marginally
severe chance will be dependent on later timing of activity.

just a modest cooldown is expected for thursday as 850 mb temps dip
back toward 10 c underneath drying northwest winds. fast pseudo-
zonal flow over northern conus with an upper level ridge arriving
friday should maintain dry weather into saturday morning before a
low chance of showers arrives for the second half of the weekend.
the amplitude of the trough swinging through varies amongst the
medium range models. none-the-less, euro ensembles support just a
modest cool down for sunday, with temperatures remaining slightly
above normal.

south turning southwesterly winds strengthen tonight into wednesday
as seasonably strong low pressure system tracks across southern
canada into hudson bay. while a gust or two two could reach entry-
level gales over central lake huron, winds are expected to peak
around 30kts. small craft advisories are in effect for the saginaw
bay/tip of the thumb through wednesday evening as a result. return
of a humid airmass back to the region will support shower and
thunderstorm chances for much of the day wednesday before the
attendant cold front crosses late evening. moderate northwesterly
flow follows for thursday however only a glancing shot of cold
advection and a rapidly diminishing gradient has high pressure
builds caps winds aob 30kts.
