.DISCUSSION...
Issued at 115 AM CDT Sat May 9 2026

An area of light to moderate rain with isolated thunder
will continue to move through much of the PAH forecast area (fa)
through the rest of the night, with models indicating the
activity lessening overall as it moves east, with the activity
moving east of our area by daybreak. The most substantial
rainfall of a quarter inch or more will be north of Route 13 in
southern Illinois, with lighter amounts farther south and east.

Dry conditions can be expected today and tonight, with much
warmer temperatures. Highs will reach around 80 degrees today
under mostly sunny skies, with seasonable lows tonight in the
middle to upper 50s.

Models bring a weak cold front through our area late Saturday
night, followed by a weak upper level wave Sunday. Any
convection will be with the upper wave. With better moisture to
our south, shower and thunderstorm chances (30-40%) will be
focused across southern portions of southeast Missouri and west
Kentucky from late Sunday morning into Sunday night. Rainfall
amounts will be less than a tenth of an inch.

Cooler air will filter in late Sunday into Monday. We will see a
broad temperature gradient Sunday, with highs ranging from the
upper 60s northwest to around 80 degrees southeast, then by
Monday, readings will be below normal across the entire PAH fa
in the upper 60s to lower 70s.

Tuesday night, models show a surface low moving through the
Great Lakes region, dragging a cold front through our area.
Moisture will really be lacking. The model blend produces 30-40%
chances of showers and storms mainly across southern Illinois,
southwest Indiana, northwest Kentucky and the Pennyrile region,
but rainfall amounts are meager, showing a couple of hundredths
at best. Beyond Tuesday night, there are currently no
indications of any worthwhile rain chances through Friday.

Temperatures for Tuesday through the end of the week will
moderate back to near to a little above normal, with the warmest
conditions on Friday as a return of south winds helps push
temperatures into the 80s.
