.SHORT TERM...
(Tonight through Friday Night)
Issued at 1045 PM CDT Wed Aug 19 2026

Short range models have been a complete mess handling upstream
storms over MO and this has complicated our storm forecast for
tonight. Latest trends bring storms in later than our previous
forecast, perhaps as late as 2 or 3 AM CDT in our northwest. How
far south storms develop is also a bit uncertain, but even if the
main MCS tracks up in KY, it should still push some outflow storms
down into the Mid State. Our far southern counties may not see
any rain through the night.

A severe risk continues with the storms, mainly damaging wind gusts.
A brief tornado cannot be fully ruled out, but storms should be
outflow dominant with relatively stable boundary conditions here
compared to upstream areas. Local heavy rain will be a concern,
mainly in the northwest.

Pockets of showers and storms will linger into the morning as a
diffuse frontal zone approaches the area. Much of midday will be
rain-free. Then, after the atmosphere recovers, additional
scattered storms will form along the weak frontal zone as another
impulse crosses the area. This time the greatest severe storm and
heavy rain potential will be located across our southern and
Plateau counties. Local damaging wind gusts will be the concern
in the afternoon as capes climb above 2000 with dcape values over
1k.

Some additional shortwave energy will cross the area Thursday and
Friday with a low chance for more showers and storms, mainly south
and Plateau.

.LONG TERM...
(Saturday through next Thursday)
Issued at 1045 PM CDT Wed Aug 19 2026

Slightly less humid air will move in with temperatures staying
around normal through the weekend and into early next week. Rain
chances look very low for the weekend. The upper high will push
eastward early next week which means temperatures and humidity
will start to creep up toward mid next week.
