.DISCUSSION...
Issued at 122 AM EDT Wed Apr 2 2025

Near term, dvlpg convection acrs cntrl IL will expand northeastward
through daybreak in response to continued/sharp low level moisture
advection. In time, overspread of better low level theta-e ridge
beneath at least modest mid lvl lapse rates will promote some small
hail risk with elevated storms within nwd advancing srn flank of
storms later this morning.

Focus then turns to potentially more active period this
evening. Severe risk remains conditional owing to debris cloud
cover, morning convective overturning, poor mid lvl lapse rates
and limited low level theta-e plume. Exception lies south of
US24 where more vigorous diurnal heating is likely to occur and
generally removed from any spoiler morning storms and where
better overlap of the parameter space for supercells exists.
Regardless volatile kinematic env in place by evening with
extreme 0-3km shear present as denoted in all cam based
hodographs warrants much caution this evening.

Otherwise cold frontal boundary sweeps through the area this evening
downstream of intense cyclone lifting through the upper midwest. Mid
lvl dryslot and mixing will promote a mild and windy day Thu post
frontal. Sfc boundary stalls down near the OH river late Thu in
response to primary upper trough hanging back over the desert
southwest. This pronounced wave will eject out into the srn plains
Sat and mix frontal zone back north into the OH valley late Fri-late
Sat with likely several rounds of deep convection and some flood
risk in at least far srn zones.

More pronounced mean troughing dvlps thereafter through ern Canada
which in turn yields much cooler wx next week with showers at times
as a series of upper disturbances drop down through amplifying ern
NOAM flow.

.AVIATION /12Z TAFS THROUGH 12Z THURSDAY/...
Issued at 702 AM EDT Wed Apr 2 2025

Area of showers and thunderstorms has blossomed over both TAF
sites and will persist for at least the first few hours of the
period. Vsbys have been impacted with the activity, but cigs
have generally behaved thus far. Some indications that precip
could either linger or redevelop early afternoon especially at
KSBN. TAFs do not reflect this for now, but trends will need to
be watched. Line of storms as well as some activity ahead of the
line is still expected later this afternoon and evening. A
period of MVFR/IFR is possible as they pass.
