.DISCUSSION...
Issued at 257 AM CDT Mon May 4 2026

An upper level disturbance crossing through the Midwest tonight
has produced showers and thunderstorms tracking east-
southeastward through Central Illinois. Areas along the I-64
corridor and Evansville Tri-State have a 20-40% chance of
showers through dawn. Some small hail can`t be ruled out but
approaching storms have lost the severe potential some of them
carried further northwest.

Lingering slight chances of showers continue in the far north
Monday while dry conditions are expected elsewhere. Breezy
southwesterly winds ramp up today with sustained winds of 15-25
mph and gusts of 25-35 mph. A Lake Wind Advisory has been issued
for the forecast area. Considering RHs bottoming out around 30%
today, along with dry soil conditions, these breezy winds will
also result in elevated fire weather conditions.

Low pressure today over Ontario trails an extended cold
front southwestward to the Central Plains. Models, especially
the CAMs, have trended towards drier conditions for the Quad
State today and delayed onset of activity tonight to almost
exclusively after midnight. Showers and storms become widespread
by early Tuesday, with numerous showers (80-100% chance) Tuesday
and Tuesday night when the cold front slowly drifts southward
through the Quad State. Before that happens, breezy
southwesterly winds will continue Tuesday. The best potential
for some strong to severe storms will be Tuesday afternoon and
evening, which has a portion of SEMO upgraded to a D2 Slight
Risk as low pressure organizing in Oklahoma/Arkansas begins
tracking east-northeastward along the front. Models have varied
timing and positioning of MCS features, some of which would keep
severe weather south of the Quad State. Monday night-Tuesday
morning activity muddies the picture for what follows.

Shower and thunderstorm activity decreases following the front,
but remains through at least the day Wednesday, mainly in
Western Kentucky. Overall QPF remains around 1-1.75in which
should provide beneficial rains for the ongoing drought, without
causing much of any flooding issues.

Late week/weekend activity is fairly likely but carries
uncertainty with a split flow in the west that meets up near the
Quad State. A cutoff low is located in the Desert Southwest
late week while systems plunging southeastward from the
northwest around a ridge. One of those northern track systems
reaches the Midwest Friday and may extend a cold front through
the Quad State but NBM PoPs have been reduced to a slight
chance Friday night so this could well stay north and/or weaken.
Sunday PoPs in the chance range are a mix of ensemble members
placing the Quad State either on the northern side of the
eastward progression of the cutoff low, in the path of the next
disturbance from the northwest, or some of both.

Temperatures surge today with gusty southwesterly winds, lifting
highs to around 80. Continued southerly breezes keep lows
tonight in the upper 50s to near 60. Rainy conditions Tuesday
limit highs and the cold front Tuesday night will return us to
well below normal temperatures mid-week. A warming trend
afterwards lifts highs to the mid-70s next weekend.
