Synopsis
Low pressure will cross the upper great lakes today with a cold
front settling south across the area this evening. High pressure
from the northern plains will build east across the region on
Friday. A warm front will lift north on Saturday then sink south
again on Sunday maintaining a focus for active weather.

Near term through Friday
Update... Adjusted pops and clouds based on quickly changing
radar and satellite. Quick look at afternoon forecast sounding
imply we may not be quite done with convection. Mfd forecast li
at 4pm is -8c with capes over 2800 j kg so boosted afternoon
pops back into the southern tier. No other significant changes.

Original... Low pressure is located over the arrowhead of
minnesota this morning with a cold front extending south across
illinois. The forecast area is starting off in the warm sector
ahead of an MCS tracking across indiana. This convection has
been maintained overnight as an upper level wave rides out of
the plains towards the southern great lakes with a 65 knot low
level jet. This jet is providing tremendous moisture advection
into the region, working to overcome the very dry air noted
above 900mb on the 00z dtx sounding. The 08z SPC mesoanalysis
shows a large pw gradient across the state of indiana with a 0.6
inch pw near toledo and 1.7 inches near chicago. It is unclear
to what extent this drier air will have on causing this complex
to weaken as it approaches the i-75 corridor towards 11z or if
the MCV and steep mid-level lapse rates will be sufficient to
maintain storm intensity and prompt convective warnings towards
sunrise. The rap suggests a corridor of instability will advect
north ahead of the line with 750 j kg of ml cape, helping to
maintain intensity until at least 8-10 am before starting to
weaken. There is high confidence that thunderstorms with
considerable lightning will move across the area this morning
but at some point convection may become elevated, lessening the
threat of severe weather. Coordination will continue with the
storm prediction center this morning and severe thunderstorm
watches warnings will be issued if needed. Latest runs of the
hrrr indicate convection will be almost east of the forecast
area by 16z.

Morning thunderstorm activity will stabilize the atmosphere and take
some time to recover into this afternoon. However many areas will
clear out this afternoon allowing temperatures to approach 80
degrees with good mixing and breezy southwest winds gusting to 30
mph. Dewpoints will remain high in the mid to upper 60s ahead of the
cold front this afternoon and expect CAPE values of 1000 j kg or
more to develop across the southern counties. Sufficient forcing
along the cold front may support redevelopment of scattered showers
and a few thunderstorms this afternoon in the 21-01z time frame. We
will monitor any storms to develop but expect the primary severe
weather threat today to be this morning.

High pressure will build in behind the front for Friday bringing a
drier airmass and cooler temperatures. Highs on Friday will range
from the mid 60s at the lakeshore to upper 70s south with thickening
mid-cloud from the west during the afternoon.

Short term Friday night through Sunday night
Upper ridge will build over the ohio valley great lakes Friday night
as a surface warm front lifts north of the area. A southwesterly low
level jet will nose northeastward into the southern great lakes late
Friday night into Saturday. Most of the overnight will be dry across
the area, however some increased chances for precip arrive on the
periphery of the LLJ by early Saturday morning. Instability will
increase across the region through the day Saturday as a mid level
shortwave approaches the region from the west. Good mid level flow
and unstable conditions will result convection increasing across the
area ahead of the wave, with the potential for some diurnally driven
strong to possibly severe storms. Low level lapse rates will be
steep with decent mid level lapse rates, and enough deep
layer effective bulk shear to organize convective, initially
discrete and possible growing upscale into something linear, with
large hail damaging winds possible. The threat will be contingent
upon how unstable the area gets through the day and the timing of
any mid level forcing. Given the synoptic pattern Saturday night, it
isn't out of the question that we could have upstream convection
develop and move eastward into the area by early Sunday morning. A
more potent wave is expected to track eastward across the region
Sunday afternoon, with another round of convection expected. Model
differences with the exact track timing of the forcing precludes
anything more than low likely high chance pops Sunday tapering to
slight chance chance pops Sunday night. Highs on Saturday will be in
the low to mid 80s for much of the area, but will be a touch cooler
Sunday in the upper 70s to low 80s.

Long term Monday through Wednesday
A brief lull in the active weather regime is expected Monday with a
more amplified longwave pattern setting up and a period of ridging
over the region Monday into Monday night. A warm front will lift
north through the area Monday night into Tuesday as low pressure
tracks northeast through the western great lakes, with some slight
chance low chance pops forecasted. Upper ridging will hold across
the region Tuesday, although the ridge will be a bit more flattened
over the great lakes. Pops increase Tuesday night into Wednesday as
low pressure tracks through the great lakes bringing a frontal
boundary towards the area. Still kept pops in the low to mid chance
range during this period with the better forcing west of the area,
although the region will be unstable in the warm sector. Highs will
generally be in the upper 70s to low 80s through the period.

Aviation 12z Thursday through Monday
Thunderstorm complex moving east across the area will bring
thunderstorms with strong winds to areas from mfd-cle eastward
through 15z. Gusts to 40 knots will be common with gusts to 50
knots possible. Brief heavy rain with ifr visibilities will be
possible.

After the morning activity moves through, the airmass will try
to destabilize from mfd-cak and points south after 21z.

Scattered thunderstorms may re-develop this afternoon in this
area and may need to be added to the terminals.

By late morning we will start to see southwest winds become
breezy with gusts to around 25-30 knots. Winds will drop off to
5-15 knots tonight as they shift around to the northwest behind
a cold front.

Outlook... Non-vfr possible in thunderstorms Saturday and Sunday.

Marine
Low pressure tracking across the great lakes today will bring a cold
front to the western end of the lake this afternoon, crossing the
lake by the overnight hours. Southwest winds today ahead of the
front will increase to 15-20 kts before becoming more west to
northwest and weakening behind the front tonight. There may be a
need for a small craft advisory on the western half of the lake this
afternoon into this evening, however winds will remain just below
criteria, and shore parallel flow should keep waves in the 2-4 ft
range. High pressure will build east across the lake tonight through
Friday before the front lifts back north across the lake as a warm
from late Friday night through Saturday morning. This will keep
winds out of the west southwest across the lake through Sunday,
until another cold front sweeps across the lake, with winds becoming
west to northwest Sunday night into Monday.
