.NEAR TERM...
(Rest of today and tonight)
Issued at 135 PM CST Tue Dec 3 2024

Winds have returned to southerly early this afternoon as surface
high pressure settles to our east and slowly weakens. Southerly
flow and increasing moisture will help keep temperatures warmer
tonight than the past several nights, with lows in the upper 30s
to low 40s for most of the area. A surface trough will move into
the area tomorrow, veering our flow to a more downsloped
southwesterly direction and allowing high temperatures to reach
the low to mid 60s within the trough axis from western north Texas
into central Oklahoma. To the south of this axis, expect
increased cloud cover and a chance for showers as a weak wave
tracks across Texas, keeping temperatures a bit cooler across
southern/southeast Oklahoma. Slightly cooler temperatures are
also expected across northern Oklahoma where winds will turn more
northerly behind the surface trough.

.SHORT TERM...
(Wednesday through Thursday night)
Issued at 135 PM CST Tue Dec 3 2024

Surface ridging will build southward on Thursday ahead of high
pressure centered across the northern plains. This will bring a
reinforcing shot of cooler air to the region, with highs dropping
back into the 40s Thursday for much of central and northern
Oklahoma, with low to mid 50s further south. Another widespread
freeze is then anticipated for Thursday night into Friday morning.

.LONG TERM...
(Friday through next Monday)
Issued at 135 PM CST Tue Dec 3 2024

Synoptic uncertainty increases Friday into the weekend as models
struggle to handle the ejection of a cutoff low spinning over the
southwest U.S., though nearly all ensemble solutions suggest a
warming trend. Low rain chances (20-30%) will also return to
southern parts of the forecast area over the weekend (centered
mainly on Friday night).

Another cool down is then forecast with our next front sometime
early next week, though models are exhibiting typical levels of
disagreement from this range regarding the timing and amplitude of
this next trough.

.AVIATION...
(06Z TAFS)
Issued at 1104 PM CST Tue Dec 3 2024

There are still three primary issues for the aviation forecast
this evening: 1) Low-level non-convective wind shear in north
central Oklahoma overnight, 2) A cold front moving through the
area with association wind shift, and 3) scattered showers and
MVFR (and locally IFR) ceilings in southeast Oklahoma Wednesday.

Southwesterly winds of 40-50 knots are expected around 2,000 feet
AGL overnight in north central Oklahoma overnight which will
create sufficient low-level non-convective wind shear to include
in TAFs at KPNC and KSWO. Some models suggest that it could be
close to LLWS threshold at KOKC and KOUN. Winds aloft are not
expected to be quite as strong in north Texas or far southern
Oklahoma.

A cold front will move into northwestern Oklahoma near or just
after sunrise on Wednesday and move southeast through the area
during the day. Winds will veer to southwesterly and westerly
before the cold front, with winds becoming northerly after the
cold front moves through.

Stratus with MVFR ceilings are expected to spread into
southeastern Oklahoma (including KDUA) on Wednesday morning with
some local IFR ceilings possible in the afternoon. Scattered
showers may also move into southeastern Oklahoma in the late
morning and afternoon.

Winds will become light and clouds decrease Wednesday evening.
