Area Forecast Discussion
National Weather Service Lincoln IL
557 AM CST Thu Feb 23 2023

.SYNOPSIS...
Issued at 336 AM CST Thu Feb 23 2023

Windy conditions will develop across central Illinois today as a
cold front passes through the region. High temperatures will be
achieved during the morning...ranging from the lower 40s in the
Illinois River Valley to the lower 60s far southeast around
Lawrenceville. Readings will steadily fall through the afternoon.

&&

.SHORT TERM...(Today and tonight)
ISSUED AT 336 AM CST Thu Feb 23 2023

09z/3am surface analysis shows a 1004mb low over far eastern Iowa
with a warm front extending southeastward along a Moline to
Lafayette, Indiana line. Meanwhile the trailing cold front is
crossing the Mississippi River. With southerly winds in place
across the majority of the KILX CWA, am expecting temperatures to
continue to rise over the next couple off hours before the cold
front pushes eastward to the I-57 corridor by mid-morning, then
into Indiana by around midday. Resulting temperature forecast
will be tricky, but think daytime highs will range from the lower
40s in the Illinois River Valley...to the lower 60s along/southeast
of a Robinson to Olney line. Once the front passes, brisk westerly
winds gusting 25-35mph will cause temps to fall throughout the
remainder of the day. Breezy and cold weather will be on tap for
tonight as lows drop into the teens and lower 20s...and wind-chill
values dip into the single digits along/west of I-55.

.LONG TERM...(Friday through Wednesday)
ISSUED AT 336 AM CST Thu Feb 23 2023

After a chilly Friday, a warm and mostly dry weekend is
expected...with highs in the middle to upper 40s on Saturday and
in the middle 50s on Sunday. After that, attention turns to the
next approaching storm system slated to impact the region early
next week. Short-wave energy evident on latest water vapor imagery
off the coast of Washington/Oregon will dive southward, forming a
closed upper low over California this weekend. As additional
short-wave energy drops southward, it will eject the California
low E/NE into the Midwest by Monday. This system and its associated
surface low will take a similar track to the previous system.
Given vigorous upper dynamics, a stronger surface low, and
adequate deep-layer moisture from the Gulf of Mexico, confidence
is growing that another potentially heavy rainfall event will
unfold Sunday night into Monday. Early projections suggest storm
total rainfall of 1 to 1.50 across central Illinois, but these
numbers could rise...especially if convection comes into play.
Have added slight chance thunder to the forecast Sunday night, but
thunder may also be needed during the day Monday as the surface
low arrives. Once the system departs, mild and dry weather will
return for Tuesday and Wednesday.

&&

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 557 AM CST Thu Feb 23 2023

Cold front is currently pushing across the I-55 corridor. Based on
area obs, FROPA will be accompanied by an abrupt wind shift to the
W/NW with gusts of 20-25kt and a lowering to MVFR ceilings. A
brief one-hour period of IFR ceilings is likely at both KSPI/KDEC.
While the initial band of low clouds associated with the front may
scatter for a short time after sunrise, a larger area of MVFR
ceilings across Iowa/northern Missouri will pivot eastward into
central Illinois later this morning, then linger through the
afternoon. HRRR paints a gloomy picture of low clouds sticking
around into the evening before gradually scattering late tonight.
Westerly winds will gust 20-25kt today, then will veer to N/NW
and decrease to 10kt or less overnight.
