.SHORT TERM...
(The rest of tonight)
Issued at 842 PM CST Wed Feb 15 2023

Storms from NE OK through south central OK have expanded in
coverage the last few hours with scattered svr storms ongoing
nearer the moisture defined warm front extending through SE OK.
This has verified well with the recent short term guidance and the
evening update will accept the near term solutions of expanding
storms eastward as the cold front begins to surge eastward.
Ongoing forecast has this well handled the update will largely be
to refine timing of the higher precip chances. The severe
potential also looks to be highest along and south of Interstate
40 where a window of more substantial moisture return remains
possible.

&&

.LONG TERM...
(Thursday through Wednesday)
Issued at 200 PM CST Wed Feb 15 2023

Cold and breezy conditions are expected behind departing system into
Thursday and continue through Thursday night.  Wind chill indices
are forecast to fall into the teens across much of the area by
Friday morning although winds will begin to decrease as surface high
pressure continues to build over the region.

Quiet weather anticipated with a warming trend over the weekend into
early part of next week. Still some significant timing differences
in the operational models with cold front mid week, but
precipitation chances will once again increase during the Tuesday,
Wednesday time frame as upper system approaches. Stayed close to
NBM guidance through the extended periods.

.AVIATION...
(00Z TAFS)
Issued at 535 PM CST Wed Feb 15 2023

Showers and thunderstorms developing in South Central Oklahoma
will continue to develop and spread east/northeast into Eastern
Oklahoma and Northwest Arkansas this evening. Greater potential
for thunderstorms is expected along/south of a surface frontal
boundary over East Central Oklahoma and Northwest Arkansas. Will
continue Tempo groups for timing of greater potential. This
activity is forecast to push off to the east and northeast into
the overnight hours as the front exits and an upper level low
pressure lifts northeast through the region. Behind the
front...MVFR/IFR ceilings and breezy west to northwest winds are
forecast to spread across the CWA tonight and continue into
Thursday afternoon. Late in the TAF period there is potential for
parts of Eastern Oklahoma to try lifting back to low end VFR.
