.SYNOPSIS...
Issued at 223 PM CDT Sat Jul 24 2021

Isolated to scattered storms remain possible into this evening as
cold front moves into the area. Some of the storms could be
severe with damaging winds the primary threats. Despite the front
moving through the area tonight through tomorrow, warm weather
will continue into next week.

&&

.SHORT TERM...(This evening through Sunday)
ISSUED AT 223 PM CDT Sat Jul 24 2021

Isolated showers developed across the area and continued to the
east, getting east of I-57 this afternoon. As these showers move
east late this afternoon, there should be a dry period into early
afternoon before a cold front drops into the area. As the front
moves into the humid airmass, characterized by dwpts in the mid to
upper 70s, additional thunderstorms will develop along this front
and move east and southeast across the area. Higher pops will be
early this evening before things diminish after sunset. So likely
pops are expected in the north before midnight with chance pops
across the middle of the CWA after midnight. The front will move
south into tomorrow with the chance of pops remaining southeast of
I-70.

Overnight lows will remain quite warm with lower to middle 70s
expected. Highs tomorrow will still be around 90 even through the
front will be south of most of the area.

.LONG TERM...(Sunday night through Saturday)
ISSUED AT 223 PM CDT Sat Jul 24 2021

The front will remain over southern IL tomorrow night and Monday
with isolated to scattered showers and storms possible. Beyond
that, dry weather is expected through Wed night. Temps may cool a
tad but temps will return to the lower 90s by mid week. Isolated
to scattered storms will return the end of the week and into the
weekend as another frontal boundary drops into the area from the
north. Temps will also remain quite warm on Thursday, but as the
boundary drops into the area, clouds and some precip will allow
temps to drop back into the middle 80s for Friday and the weekend.
