.SHORT TERM...
(The rest of today )
Issued at 1051 AM CDT Wed May 22 2024

Ongoing storms are aligned along and north of a cold front which
is make slow but steady progress southward through SE OK and west
central AR. This trend will continue through the day with the
focus for strongest storms gradually shifting southward with time.
The severe threat will decrease from north to south across the
forecast area and likely be south of the Red River by late
afternoon. Updated forecast has adjust for precip trends in the
near term and incorporated observed trends.

.LONG TERM...
(Tonight through Tuesday)
Issued at 401 AM CDT Wed May 22 2024

Shower and storm chances will be greatest tonight across southeast
Oklahoma, but if convection today forces the surface boundary too
far south, coverage and intensity of storms tonight may end up
being less than forecast. The frontal boundary starts to return
north and wash out Thursday as an upper wave approaches from the
west. This will result in another round of showers and storms
Thursday afternoon and evening, with southern and eastern areas
once again favored for greatest storm coverage and heaviest rain
amounts.

A relative lull in convection is expected Friday into Saturday
afternoon before storm chances ramp up again late Saturday and
Saturday night as another upper wave moves across the area. A cold
front will follow the passage of this system, with drier weather
returning Sunday into next week as the upper level pattern changes
to a more northwest flow. There is still some uncertainty as to
whether we will be completely dry early next week, so just rode
with the NBM pops for now which keeps most of the area dry.
Temperatures through this period look to be near the seasonal
averages for late May.

(18Z TAFS)
Issued at 1221 PM CDT Wed May 22 2024

Ongoing scattered storms will continue to periodically impact
terminals through the afternoon with low VFR to MVFR ceilings at
most times. Convective coverage should wane this evening with low
clouds and/or areas of fog developing late tonight. Flight
conditions improve mid to late morning with additional storms
possible just beyond this forecast time frame.
