.DISCUSSION...
Issued at 348 AM CDT Tue Sep 30 2025
Today and Wednesday...
Temperatures this morning are currently sitting in the 60s with
southerly winds and mostly cloudy skies. A passing shortwave trough
is moving through southwesterly flow aloft. Widespread cloud
coverage from this passing shortwave trough will help keep
temperatures slightly cooler than previous days, with highs in the
upper 70s to low 80s. Lift from the aforementioned shortwave
trough will also result in scattered radar returns throughout
much of the day. There is a fair amount of dry air near the
surface which should prevent any of the rain from reaching the
ground. Southerly winds will be breezy again this afternoon,
strongest west of Highway 281 gusting 20-30mph.
Another passing shortwave trough moves into the Plains Tuesday night-
Wednesday morning. Lift from this system aided by the LLJ will
support the development of scattered showers early Wednesday
morning. There remains some uncertainty on how much precipitation
develops and the impacts of dry air. Because of this, the forecast
was kept dry (PoPs < 15%) but may be added later if confidence
increases. If rain were to occur, any accumulations would be very
light (less than 0.05"). Any showers will come to an end by the mid-
morning hours as the LLJ weakens/veers. Skies will clear as
temperatures climb into the mid 80s during the afternoon.
Thursday and Friday...
Southwesterly flow-weak riding builds over the area on Thursday and
Friday. Due to this, well above normal temperatures are expected
across the area. Highs will soar into the mid 80s-low 90s, 10-15
degrees above their climatological normals. Mostly sunny/sunny skies
are expected. Breezy winds are expected Friday afternoon, gusting 20-
30mph.
This Weekend Onwards...
Another warm breezy day is expected during the day on Saturday ahead
of an approaching longwave trough with highs in the 80s-low 90s.
There remains some disagreement within global model guidance as to
the timing, strength and position of this trough. Still, the GFS and
ECMWF support a cold front pushing it`s way into the area sometime
Saturday night-Sunday. Scattered thunderstorm development along the
front brings the next chance for precipitation to the area but
models disagree on how widespread rain will be across the area.
Cooler weather is expected behind the cold frontal passage on
Monday, with highs in the mid 60s to low 70s.
