.SHORT TERM...(Today through Friday)
Issued at 323 AM CDT Tue May 4 2021

Latest surface analysis show a cold front extending from near
Interstate 64 in southwest Indiana to just south of Marion
Illinois to near poplar Bluff Missouri. A line of strong to severe
storms extended from Ellsinore Missouri to Paducah to Greenville
Kentucky moving north. This line of convection will continue north
over the next few hours with isolated cells possible both north
and south of the activity. Another line moving east-northeast out
of Arkansas will trek across southern portions of west kentucky
through daybreak.

Timing of the frontal passage today remains in question due to
drastic model differences. It looks like the front will remain
draped across our region much of the day, and daytime heating will
help convection continue to develop or redevelop, especially by
late morning and this afternoon. The front should finally push
southeast of our region this evening, allowing showers and storms
to taper off from west to east this evening into the early
morning hours of Wednesday.

By late tonight, high pressure from the Central Plains will move
over the middle Mississippi valley.  This will bring dry conditions
back to our region, and keep winds out of the north into Wednesday
night. Cooler air will continue to filter in, keeping our high
temperatures 5 to 10 degrees below normal, and lows 4 to 7 degrees
below normal.

On Thursday, models have been fairly consistent in bringing a weak
surface trof across our region. This will produce isolated to
scattered showers and thunderstorms to the PAH forecast area
Thursday afternoon, with the better chances across our northern
counties.  High pressure will quickly follow, so our area will be
dry Thursday night through Friday evening.

.LONG TERM...(Friday night through Monday)
Issued at 323 AM CDT Tue May 4 2021

An active pattern is expected for the weekend.  Models show a
surface low over the Central Plains bringing a warm front north into
the middle Mississippi and lower Ohio valleys late Friday night into
Saturday.  Models show the front lifting north and setting up shop
just north of the PAH forecast area by late Saturday into Saturday
night.  Impulses moving along the front will keep showers and
thunderstorms in our forecast through the weekend. Small chances
of showers will move move into our western and northern counties
late Friday night, with showers and some storms spreading across
the rest of the PAH forecast area Saturday as impulses ride along
the front. Due to the expected location of the front, our highest
chances will be across southern Illinois and southwest Indiana.

By Saturday night into Sunday, the surface low to our west will
push eastward, dragging a cold front toward our region. Models
differ in how fast the cold front will move through our region
late Sunday into Sunday night, but there is some agreement that
the front will hang up just south of the PAH fa. Generally,
showers and storms will remain in our forecast through Monday.

&&

.AVIATION...
Issued at 626 AM CDT Tue May 4 2021

Thunder chances will end from west to east around 12-15z, though
kept vicinity showers going through most if not all the remainder
of the forecast period. Cigs will lower to MVFR under rain
shower activity. After the steady rain ends, cigs will remain in
the low MVFR range or deteriorate further to IFR levels depending
on location. Vsbys will generally be VFR. Winds will be SW at 5-10
kts outside of thunderstorms this AM, becoming W-NW this
afternoon behind a passing cold front.
