.DISCUSSION...
Issued at 1230 AM CDT Mon May 11 2026

Longwave trough currently setup across the Upper Red River Valley
and will be moving into the Middle Red River Valley of SW AR, SE
OK and NE TX by mid morning with the trough axis exiting our
northeast zones by this evening. Through sunrise, not as concerned
as we once were with the probability of widespread severe storms
but upper forcing in advance of the trough should allow for
plenty of showers and thunderstorm activity moving through our
region over the next 12 to 18 hours before the precipitation
begins to move to our east. Heavier rainfall amounts should be
oriented near but especially south of the I-20 Corridor through
late this afternoon.

Beyond Today, sfc ridge axis to move through our region during the
day Tuesday but another weak frontal boundary may try to backdoor
its way into our region during the day Wed which would allow for a
return to northerly winds. A weak wind shift is about all this
backdoor frontal boundary will do to our region as high
temperatures by Wed into Thu will be near 90 degrees across most
locations. The warmup will be due in part to upper ridging that is
currently across the Desert Southwest with this feature moving
into the Texas Hill Country by Tue Night/early Wed and into the
Southern Plains by Thu/Thu Night.

Will be watching our next trough of low pressure quickly moving
into the Intermountain West in the wake of the upper ridge axis by
late in the work week. Latest GFS is much more vigorous with this
trough by next weekend which would at the very least support a
chance of showers and thunderstorms for the upcoming weekend while
the ECMWF is supporting much more of an open wave trough which
would not support much in the way of precipitation. Latest NBM
output is mostly dry for Sat with only slight chance pops across
portions of our region for Sunday which is a happy medium this far
out in the forecast until the next trough evolution comes into
better play.

.AVIATION...
(06Z TAFS)
Issued at 1230 AM CDT Mon May 11 2026

For the 11/06Z TAFs, CIGs have begun deteriorating at quiet
terminals, reaching IFR and LIFR with periodic VSBY reductions.
Where CIGs have not yet come down from MVFR, lowering is expected
overnight towards daybreak. Showers and thunderstorms in deep east
Texas will impact KLFK through the night, with possible spreading
north and east towards dawn and into the daylight hours. Current
timing projections recover CIGs to mVFR by midday, scattering out
into the afternoon and remaining VFR through to the end of this
forecast period. Light and variable winds will become northeast
through the period, reaching maximum sustained speeds of 5 to 10 kts.
