.SHORT TERM /THROUGH TONIGHT/...
Issued at 132 AM CDT Thu Aug 20 2026

Satellite and radar early this morning had the storms that
developed in south central Missouri having moved to the east.
The upper level flow pattern remains northwesterly with a few
weak shortwaves moving through the pattern. This will bring
some cloud cover to the area, though high pressure north of the
region will help keep things dry today.

Lingering moisture across the region, light northerly winds and
clear skies along and north of I-44 this morning will help bring
the potential for some patchy areas of fog this morning.
Expectations are for periods of a mile or less at times, and a
Dense Fog Advisory may be needed but will monitor conditions
through the morning.

Thanks to the surface high north of the region, today is
expected to by dry with a temperature gradient from northeast
(Temps in the middle 80s) to southwest (temps in the middle 90s)
with generally light northerly winds.

For tonight into Friday morning, a weak wave may be enough to
bring a few showers to far southwestern Missouri but most
locations will remain dry. Overnight temperatures will be in
the middle 60s (northeast) to around 70 (southwest).

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Issued at 132 AM CDT Thu Aug 20 2026

The upper level northwest flow pattern is forecast to remain in
place through at least the weekend, and perhaps into early next
week. With a decent 850mb temperature gradient possible, from
southwest to northeast, the warmest temperatures should be west
of Springfield. Highs in the mid/upper 90s are likely in these
areas, especially locations where drought is increasing.
Afternoon dewpoints continue to come in lower with middle to
upper 60s. This is expected to keeping heat indicies at or below
100. The NWS Heat Risk tool shows mainly moderate levels with
some increase to major by the end of the weekend and next week,
most likely due to the prolonged heat.

Some slight rain potential is being hinted at (20 percent or
less) for areas into the weekend and early next week. Ensembles
continued to trended a little wetter, though depending on
timing of waves moving down the northwest flow aloft may
determine where rain does develop. If the ridge remains further
west of the area, then precip chances would be less and more
confined west of the area. Confidence remains low during this
time frame but will keep watching the latest trends going
forward.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1216 AM CDT Thu Aug 20 2026

Flight conditions across the region will initially be VFR with
some fog potential by early morning. Fog is possible mainly at
KSGF into  morning, but the site will be toward the southern
extent of the fog bank, so predictability is low.

Otherwise, surface winds will be generally light and variable.
