.NEAR TERM...
(Rest of today and tonight)
Issued at 1237 PM CDT Wed Sep 3 2025

Today will be warmer than yesterday, especially across our western
and northern counties ahead of an approaching cold front.

This evening, the aforementioned front will bring low rain chances
(10-20%) to northern Oklahoma. If we get storms, a few could become
strong to severe as instability and shear will be sufficient for
hail (up to 1 inch) and damaging winds (up to 60-70 mph). Storms
will likely dissipate quickly after sunset with the loss of daytime
heating (here, the NAMnest is an outlier, keeping some isolated
activity progressing southward through the night, possibly aided by
a weak low level jet).

.SHORT TERM...
(Thursday through Friday night)
Issued at 1237 PM CDT Wed Sep 3 2025

The aforementioned weak front is expected to stall in southern
Oklahoma Thursday morning. The airmass behind this front will not be
appreciably cooler, so Thursday`s highs will be similar to today`s
across most of the area. The one exception will be southwestern
Oklahoma and western north Texas, where a thermal ridge could push
highs in the mid and upper 90s.

A stronger cold front is forecast to approach from the north late
Thursday night into Friday. This will bring the next chance for
showers and thunderstorms to the area (mainly northern Oklahoma
through the day Friday). A notable temperature gradient is expected
across the forecast area on Friday afternoon as this front pushes
south, with highs ranging from the upper 60s / low 70s in northern
Oklahoma to the low/mid 90s in the Red River Valley.

.LONG TERM...
(Saturday through next Tuesday)
Issued at 1237 PM CDT Wed Sep 3 2025

With the front lingering in/near the area, low rain chances will
continue Saturday with chances shifting into southern parts of the
fa. Models differ later this weekend into early next week but it
looks like rain chances will continue across the area during this
time period. Some of the models show the remnants of a tropical
system in the Pacific moving into and lingering in the region this
weekend into early next week. Other models show a shortwave moving
across the Plains. Both scenarios would bring the potential for
showers/storms, especially if at the very least some of the moisture
associated with the tropical system makes it into the region.

After Friday, below average/cooler temperatures are expected across
the fa over the weekend into early next week with highs back in the
70s and 80s and lows in the 50s and 60s.

.AVIATION...
(06Z TAFS)
Issued at 1041 PM CDT Wed Sep 3 2025

The thunderstorms in north central are moving southeast and will
move out of the KPNC vicinity soon. A cold front will move south
through the area overnight and Thursday, shifting the winds
briefly to northerly, although will come back around to
southeasterly Thursday afternoon in many areas. There is some
potential for MVFR ceilings in northern Oklahoma towards sunrise.
A period of non-convective low-level wind shear is expected for a
few hours early Thursday morning across the central Oklahoma
sites (KOKC, KOUN, KSWO, KLAW) with light northerly winds at the
surface and west winds around 30 knots expected around 1000 feet
AGL.
