.KEY MESSAGES...
Updated at 1221 PM CDT Fri Apr 3 2026

 - Additional round of strong to severe thunderstorms Friday
   evening with increasing heavy rainfall potential.

 - Cooler and drier conditions Sunday into early next week.

 - Unsettled pattern returns late next week.

&&

.SHORT TERM...
(Through tonight )
Issued at 1148 AM CDT Fri Apr 3 2026

Forecast remains consistent with expectation of widespread showers
and storms spreading across the local region this evening into the
overnight hours and then ending from north to south early
Saturday. Isolated to scattered convection may develop this
afternoon across E OK and NW AR but confidence remains low in this
scenario. Should a storm develop then background conditions would
support a brief strong to severe threat. Otherwise, the focus will
be the advance cold front and storms initiating on the dryline
further southwest and their progress eastward. The early evening
time frame should see numerous storms spreading into E OK with a
risk of severe weather primarily damaging winds with a more
isolated risk of large hail. The tornadic potential continues to
be appear low but non zero. With time the severe risk will
transition to more of a heavy rain risk. The combination of short
term guidance trends and background ensemble data favor a corridor
of heavier rains as the convection line slows overnight. A flood
watch has been issued for the most likely corridor of these
heavier rains.

&&

.LONG TERM...
(Saturday through Friday)
Issued at 1148 AM CDT Fri Apr 3 2026

Showers and isolated storms will be ongoing across SE OK into
western AR early Saturday but continue to end from north to south
through the morning. Dry weather and noticeably cooler
temperatures are expected are wide by afternoon. Sfc high pressure
settles over the region and remains largely in place through early
next week. A reinforcing weak cold front arrives Tuesday before
stronger return flow and warmer temperatures develop by mid week.
Shower and thunderstorm chances return by late next week.

&&

.AVIATION...
(18Z TAFS)
Issued at 1221 PM CDT Fri Apr 3 2026

A mixture of low VFR to periodic MVFR ceilings will continue
through the afternoon with a few showers and storms from SE OK
into NW AR. Widespread convection will spread across the region
this evening and persist through the overnight hours with a focus
southward with time. Aviation impacts will likely occur at all
terminals with the heaviest rains and passing storms. Ceilings
will rise into VFR levels across NE OK into NW AR Saturday morning
with lower ceilings and areas of rain likely persisting across SE
OK into west central AR.
