.DISCUSSION...
Issued at 245 PM CDT Fri Apr 4 2025

Will continue the Flood Watch from Sangamon, Macon, Piatt,
Champaign and Vermilion counties southward through 7 AM Sunday.
We are expecting an additional 1-3 inches of rainfall in this
watch area, with 3-4 inches possible in southeast IL from I-70
south. The heaviest rainfall of 1-2 inches likely occurs this
evening along and southeast of a Taylorville to Decatur to
Champaign line.

Mid afternoon surface map shows a warm front over central KY/TN/AR
and into southeast Texas. Another frontal trof was extending ne
through se MO into central IL. Widespread showers and isolated
thunderstorms lifted ne across central IL during early/mid
afternoon with thunderstorms with heavier rains sw of St Louis
area.

Latest CAMs show a lull in convection over southeast IL during late
this afternoon, otherwise widespread showers along with chance of
thunderstorms over the area through this evening and diminishing
from the nw over central IL during overnight but continue high
chances of showers and isolated thunderstorms in southeast IL. As
warm front lifts into southeast IL during this evening, we will
see increasing instability with MU CAPEs of 1800-2500 j/kg in
southeast IL along with strong 0-6 km bulk shear values of 40-65
kts. This supports SPC's slight risk of severe storms this evening
in southeast IL with enhanced risk budding into Lawrence and
southern Richland counties which gets close to the warm section by
mid/late evening when best chance of tornadoes will be. PW values
rising to 1.5-2 inches from I-55 se into this evening to support
heavy rain threat especially from I-72 south. Lows tonight range
from lower to mid 40s in central IL (coolest nw of IL river) to
the low to mid 50s se of I-70.

Another low pressure to lift ne along the frontal boundary to
our southeast on Saturday to bring another wave of moisture with
showers and isolated thunderstorms over mainly areas se of the IL
river with highest pops in southeast IL. Far southeast IL has
marginal risk of severe storms Sat afternoon but latest model runs
appears to keep stronger storms se of Lawrence county. May see
another half to 1 inch of rain from I-70 southeast on Sat and Sat
evening with heaviest amounts in far se CWA near Lawrenceville.
Highs Sat around 50F to lower 50s over much of central IL and
upper 50s/lower 60s far southeast IL. One more disturbance bring
more showers to se half of CWA on Sunday with lighter qpf amounts
generally under a tenth inch. Highs Sunday in the upper 40s and
lower 50s, coolest in southeast IL.

Not much change to the forecast during upcoming work week. A cold
front passes through on Monday and may produce a few light
rain/snow showers especially from I-74 northeast. Hard freeze
still likely overnight Monday night into early Tue morning with
low in the mid 20s central IL and upper 20s south of I-70.

IL in a WNW upper level flow during mid week with a short wave
scooting by around Wed bringing chance of showers, with good
chance of showers and isolated thunderstorms Wed night and Thu as
stronger disturbances moves in. Highs Tue in the upper 40s/lower
50s modifying into the upper 50s/lower 60s on Wed. Temps continue
to warm into the upper 60s and lower 70s Thu/Fri. The milder
pattern that returns during 2nd half of next week looks to
continue. CPC 8-14 Day outlook for Apr 12-18 has 40-45% chance of
above normal temperatures across IL with near normal precipitation
over central IL and below normal pcpn over the Wabash river
valley.
