.NEAR TERM...
(Rest of today and tonight)
Issued at 1224 PM CST Mon Nov 3 2025

Ridging will dominate the Southern Plains through today and tonight.
500 mb heights are approaching November records, especially along
and south of I-40. That will keep temperatures far above average
along and south of I-40 this afternoon. North of a weak frontal
boundary, temperatures will be merely "above-average" this
afternoon. Clear skies continue tonight with temperatures dropping
to about 50 and an increasing southerly breeze.

.SHORT TERM...
(Tuesday through Wednesday night)
Issued at 1224 PM CST Mon Nov 3 2025

The Rossby wave pattern will decrease in amplitude but increase in
wavelength tomorrow. This will increase the fetch of zonal flow
across the central US, promoting a return to seasonably strong lee
troughing. On our end, it will continue to be sunny and very warm
thanks to the strength of the ridge, but southerly winds will
increase with a tightening pressure gradient. RH values will flirt
with 20 percent along the 100th meridian (particularly if models are
showing an undermixing bias as they often do once fuels reach
dormancy). However, fuels are likely only marginally receptive to
fire, so even if fire weather reaches Elevated, concerns will still
be mitigated.

Ridging remains in the area during the day on Wednesday, but a
trough diving into the Great Lakes will push at least a weak frontal
boundary southward across the Plains. Warm mid-level temps will
preclude any potential for rain or storms, but temperatures might be
kept closer to something resembling fall along and north of the
front, at least. Highs are expected to remain in the mid-80s near
the Red River.

.LONG TERM...
(Thursday through Sunday)
Issued at 1210 AM CST Mon Nov 3 2025

Warm conditions will continue into the late week, with some (low)
potential for a pattern shift into next weekend. The warmest day of
the upcoming week is currently advertised on Thursday, with
potential for temperatures near 90-degrees across the Red River
Valley. The latest National Blend of Models (NBM) output (i.e., our
forecast) runs towards the upper end of most guidance, with only a
<10% chance for 90s when comparing over all deterministic and
ensemble output.

There are early indications our "heat wave" will break down by
Friday into next weekend as a more robust front/system impacts the
region.

become gusty from the south Tuesday morning and continue into
Tuesday afternoon. Low-level wind shear is possible overnight,
but will subside by mid Tuesday morning.
