.NEAR TERM...
(Rest of today and tonight)
Issued at 152 PM CDT Tue Mar 25 2025

The cold front is currently stalled across southern Oklahoma this
afternoon with temperatures rising towards the 80s south of the
boundary. Increased low-level moisture from the Gulf with warm well-
above normal temperatures and weak instability, there is a small
chance for some isolated thunderstorms to develop ahead of the
frontal boundary this evening. Inverted "V" soundings with high LCLs
will make for damaging wind gusts the main threat, but large hail
cannot be ruled out with any storm this evening due to steep lapse
rates and weak buoyancy in the hail growth zone.

The cold front is anticipated to continue to push southward this
evening into Texas, while overrunning warm air advection brings
moist isentropic lift to portions of western north Texas and
southern Oklahoma. Increasing low-level winds will also help support
scattered elevated showers and thunderstorms overnight tonight along
a corridor roughly from Elk City to Durant. The highest chances for
a severe storm will be across south central Oklahoma with large hail
and damaging wind gusts the main threats. Additionally,
northwesterly flow aloft will create a southeast storm motion and
thus the potential for training storms over the same area, more
specifically where the highest chances are for thunderstorms to
develop in south central Oklahoma. PWAT values will be near 1" with
moderate to heavy rainfall possible, which could lead to localized
flooding concerns in addition to the training showers and storms.
Best timing for shower and thunderstorm development will be around
Midnight and continue through roughly the early afternoon hours
tomorrow before pushing south out of the area into north Texas.

&&

.SHORT TERM...
(Wednesday through Thursday night)
Issued at 152 PM CDT Tue Mar 25 2025

Wednesday will feature diminishing showers and storms through the
morning and into the afternoon hours. Lingering cloud cover through
the day Wednesday may keep temperatures nearly 5 to 10 degrees
cooler than today. A shortwave in the flow aloft will bring
increased rain chances again Wednesday night, mainly south of the I-
40 corridor. Lack of lift and instability will give way to mostly
rain showers, but a few embedded weak thunderstorms cannot be ruled
out at this time. Precipitation chances will continue south of I-40
Thursday with elevated fire weather danger in northern Oklahoma with
breezy south winds of 10 to 20 mph and higher gusts possible.

&&

.LONG TERM...
(Friday through Monday)
Issued at 235 AM CDT Tue Mar 25 2025

There continues to be a signal in the deterministic and ensemble
suite of a pattern change towards the end of the week into the
weekend.

A weak mid-level wave will approach the area Friday, bringing
additional rain chances most of the area. The greater chances are
confined to the southern half of the area. Another wave is
forecast to move through the area over the weekend. There is still
model inconsistencies, especially with the dryslot. If the
positioning of the drier air is further west, there is a signal
for strong to severe storms along and east of the I-35 corridor
on Saturday with all hazards possible.

With these systems, surface winds are expected to be strong
enough to warrant at least elevated fire weather conditions
through the weekend.

.AVIATION...
(18Z TAFS)
Issued at 1246 PM CDT Tue Mar 25 2025

VFR conditions are expected this afternoon and much of the evening
with light east or east northeast winds. Winds will become
southeasterly Wednesday morning but remain fairly light. Showers
and thunderstorms are expected to develop tonight, mainly south of
I-40 and will linger into the day on Wednesday. MVFR ceilings are
possible across southern Oklahoma by Wednesday morning.
