Area forecast discussion, Oct 24, 7:23 PM CDT, 35 minutes before

Area Forecast Discussion
National Weather Service Lincoln IL
723 PM CDT Sun Oct 24 2021

.SYNOPSIS...
Issued at 344 PM CDT Sun Oct 24 2021

Multiple severe weather hazards exist across central Illinois late
this afternoon and evening...including the potential for flash
flooding. Be sure to review your weather safety plan and stay
situationally aware.

&&

.SHORT TERM...(This evening through Monday)
ISSUED AT 344 PM CDT Sun Oct 24 2021

20z/3pm surface analysis shows a 997mb low over northwest Missouri
with a warm front extending eastward along a Kirksville...to
Taylorville...to Terre Haute line. Temperatures have surged well
into the 70s south of the boundary, while readings hover in the
50s to the north. As expected, a couple bands of convection are
developing within the warm sector of the system. The first extends
from near Macomb southwestward to Columbia, Missouri...while the
second is further west immediately along an advancing cold front
across western Missouri. Given high degree of wind shear in the
environment, all severe hazards will be possible as the storms
track through the area late this afternoon and evening. Damaging
wind gusts and large hail will be the primary threats: however, a
couple embedded tornadoes may develop along the lines...especially
this evening for locations along/south of I-72. Based on regional
radar trends and latest HRRR, it appears the western line of
convection will push across the I-57 corridor by around
midnight...then into Indiana shortly afterwards. As the surface
low lifts into north-central Illinois late tonight, showers will
wrap back into the area and will linger through at least midday
Monday before gradually tapering off and coming to an end from
west to east during the afternoon. Main weather story on Monday
will be the windy and colder conditions. After a brief warm-up
this evening when the warm front lifts north of I-72, temps will
crash late tonight and will remain in the lower to middle 50s on
Monday. In addition, strong NW winds gusting 30-40mph will make it
feel even chillier.

.LONG TERM...(Monday night through Sunday)
ISSUED AT 344 PM CDT Sun Oct 24 2021

High pressure will build into the region Monday night, resulting
in clearing skies and diminishing winds. With low temperatures
expected to drop into the middle 30s, think patchy frost is a
good bet across the Illinois River Valley. Further east, think
temps will remain a bit too warm in the upper 30s and lower
40s...and winds will remain too strong for frost formation. After
a chilly start to the day, ample sunshine will warm readings into
the upper 50s and lower 60s.

After that, another frontal boundary will swing into the Midwest
by the middle of the week. With the associated upper low cutting
off from the main flow, this system will be slow to arrive and
slow to depart. As a result, have delayed PoPs on Wednesday...and
these may need to be further reduced or even removed entirely if
trends continue. Have then gone with high PoPs Wednesday night
through Friday before the system finally departs by next weekend.

&&

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 718 PM CDT Sun Oct 24 2021

Severe storms push through region during the first 6 hours of the
period as a frontal system progresses across the Midwest. Ceilings
will be vrb in nature, as a warm front stalls across the I-72
corridor, leaving lower ceilings across the northern sites. As the
cold front slides through, expecting ceilings to decrease back
into MVFR at all sites later tonight. Gusty winds will be possible
from south at SPI, DEC, and CMI, while remaining northerly at PIA
and BMI. Once the cold front swings through, winds increase from
the w, becoming nnw through Monday. Storms will impact the area
terminals through portions of the overnight, with the frontal
boundary moving across the Mississippi River currently. Expect
showers and storms, severe at times, throughout the first part of
tonight, possibly linger towards morning in far eastern Illinois.
