.NEAR TERM...
(Rest of today and tonight)
Issued at 155 PM CDT Tue Sep 2 2025
Satellite and radar observations depict a pair of MCVs (mesoscale
convective vortices) this afternoon. One MCV is slowly moving
southward from Kansas into north central/northeast Oklahoma this
afternoon. Another MCV is moving southeast across east central
Oklahoma. An MCV essentially behaves like an upper-level (just
smaller-scale) that provides a source of lift for clouds and
precipitation. As a result, we`ll have a chance of showers and
isolated thunderstorms this afternoon across the eastern half of
the area.
The potential hazards will be brief, heavy rainfall and cloud-to-
ground lightning. These showers and thunderstorms should
generally be diurnally-driven and should weaken this evening.

.SHORT TERM...
(Wednesday through Thursday night)
Issued at 155 PM CDT Tue Sep 2 2025
By Wednesday, southerly winds will return and a low-level thermal
ridge will expand to the east ahead of an approaching cold front.
The expanded low-level thermal ridge, return to southerly winds,
and more sunshine/solar insolation will result in a warmer day.
Temperatures will be near seasonal averages ranging from the mid
80s to mid 90s deg F.
The cold front will move through Wednesday night/early Thursday
with a chance of showers and thunderstorms as a shortwave trough
rotates across the Great Lakes region. A few strong to severe
thunderstorms are possible across northern Oklahoma in association
with the front. The risk of severe weather should decrease near or
just after sunset with the loss of daytime heating.
With the surface high quickly moving to the east and limited cold
air advection, no appreciable cool down is expected on Thursday.
As a matter of fact, some locations across southwest Oklahoma into
western north Texas may be hotter Thursday afternoon with a
strengthening low-level thermal ridge on the southwest periphery
of the dissipating cold front.

.LONG TERM...
(Friday through Monday)
Issued at 1257 AM CDT Tue Sep 2 2025
Another cold front is expected to move across the area Friday as a
stronger shortwave rotates across the northern Plains into the Great
Lakes region. Showers/storms will be possible with this front Friday
into Saturday. Models differ over the weekend into early next week
so a lot of uncertainty but it looks like rain chances could
continue across the area over the weekend into early next week.
With the front moving across the area Friday, a fairly decent
temperature gradient is forecast across the area with highs in the
mid 70s across northern OK and in the upper 80s/low 90s along the
Red River. Temperatures over the weekend into early next week will
once again be well below average with highs back into the 70s and
80s.

.AVIATION...
(00Z TAFS)
Issued at 634 PM CDT Tue Sep 2 2025
Some clouds will linger at KPNC and potentially at KSWO and KDUA
over the next hour or two, but will decrease early this evening.
But these clouds will keep a MVFR ceiling at or near KPNC until
these clouds dissipate and/or move out. The potential for some
slightly reduced visibility in BR, although the potential looks a
little lower and have removed the tempo group for this in a few
of the TAFs. Winds will become light quickly this evening.
