...New AVIATION...

.UPDATE...
Issued at 1038 AM CDT Wed Sep 18 2024

Overall trends today suggest less cloud cover, and thus a warmer
afternoon. Current temps are running at least a few degrees warmer
compared to yesterday, thus forecast highs appear on track at this
time. No changes anticipated.

.SHORT TERM...
(Today)
Issued at 329 AM CDT Wed Sep 18 2024

Showers and thunderstorms in northwest Oklahoma early this morning
are expected to dissipate before reaching our area today.
Temperatures should be warmer today due to less cloudiness, with
afternoon highs generally ranging from the upper 80s to mid 90s.

.LONG TERM...
(Tonight through Tuesday)
Issued at 329 AM CDT Wed Sep 18 2024

The warming trend will continue Thursday and Friday as an upper
ridge builds overhead, with unseasonably hot afternoon high
temperatures and unseasonably warm overnight lows. Afternoon heat
index values will reach near 105 in some places both Thursday and
Friday afternoon, so it is possible that heat headlines may be
required.

A few "sunrise surprise" showers and thunderstorms may develop
late tonight and Thursday morning across parts of northeast
Oklahoma, and the CAMs suggest the potential for robust
convection to develop across northeast Oklahoma late Thursday
afternoon, with these storms possibly propagating south as far as
southeast Oklahoma Thursday evening before dissipating. As such,
have added pops for both of these time frames despite the dry NBM.

Low shower and storm chances will remain possible in the northern
part of the forecast area this weekend, and temperatures will
lower slightly as the upper ridge over the area begins to break
down. Better shower and storm chances look to occur Sunday night
as a cold front sweeps across the area. There remains considerable
model spread in the magnitude of the cooling behind this front
for early next week, with some models...UKMET and ICON in
particular...indicating a far more significant cooldown than what
is shown in the current forecast. We will just have to wait and
see how this all plays out.
