.DISCUSSION...
Issued at 150 PM CDT Mon Sep 21 2026
An upper-level low over the northern Plains today will slowly
move east southeast into the Ohio Valley through Wednesday.
Disturbances in the cyclonic flow to its south will bring a
chance of showers to southeast Missouri this afternoon through
early Tuesday. With some lingering moisture this afternoon,
instability is building over the Ozark Foothills and a few
thunderstorms will be possible. Very localized gusty winds will
be possible to go along with lightning and brief heavy
downpours. Any instability will be lost with sunset, so no
thunder is expected tonight.
Cool, surface high pressure will continue to build across the
Quad State, and there will be plentiful cloud cover, especially
across the northern half of the area until the upper low passes
to the east of the area Wednesday. High pressure aloft will then
build overhead Thursday into Friday and possibly through the
weekend, while surface high pressure remains in entrenched over
the region. This will produce some gorgeous fall conditions.
At some point over the weekend, enough energy may impinge on
the upper ridge to bring a small chance of showers or
thunderstorms most likely to southeast Missouri and southern
Illinois, but the details are too murky at this time to get
excited about any rainfall.
