- High chances (70-80%) for thunderstorms this afternoon through

.SHORT TERM...
(This evening through Monday)
Issued at 142 PM CDT Sun May 10 2026

...Severe Thunderstorm Watch in effect through 9 PM for all
counties...

At 1 PM, a cold front was located from near Seminole east to
Stamford, and was moving south towards the I-20 corridor. South of
the front in our forecast area, surface-based CAPEs were in the
3000 to 4000 J/kg range, effective deep layer shear ranged from 30
to 40 knots, low and mid level lapse rates were both in excess of
8C/km, and an upper level shortwave was moving into the area from
the northwest. All this will come together in the next 1 to 3
hours to initiate convection near a triple point that will be near
Sweetwater, where storms have already begun developing. Expect
the initial convection to be at least semi-discrete supercells,
the strongest of which will be capable of producing very large
(2"+) hail, wind gusts over 70 mph, and potentially tornadoes.
These storms will likely experience upscale growth into a MCS
within 1 to 2 hours where the most likely hazards will transition
to mainly large hail and wind gusts over 60 mph as the complex
moves southeast through our CWA. Everywhere south of Interstate 20
will have the potential to be impacted by these storms. North of
Interstate 20 will likely see isolated to scattered strong to
severe storms, but the threat will likely be over by 5 PM this
afternoon. Storms are expected to move out of our southern
counties by 9 or 10 PM tonight.

Lows tonight will drop into the upper 50s to mid 60s. Quieter
weather is expected tomorrow, with highs in the mid 70s to lower
80s.

&&

.LONG TERM...
(Monday night through next Sunday)
Issued at 151 PM CDT Sun May 10 2026

A dry and stable pattern will prevail for most of next week.
An upper level ridge over the southwestern U.S. will migrate
eastward into our area by the middle of the week. The center of
the ridge axis will shift to the east of the region on Thursday
and Friday with generally zonal flow aloft prevailing into next
weekend. Next weekend models forecast an upper level low to deepen
over southern California and the Baja. With embedded disturbances
in the southwest flow and the dryline in play may see scattered
thunderstorm development on Sunday. For now will keep PoPs capped
at 20-30 percent but will need to watch. Otherwise, temperatures
will warm into the upper 80s to mid 90s across most of the area
from Wednesday into next weekend, with some upper 90s and triple
digits possible in the Big County on Friday and Saturday.

.AVIATION...
(18Z TAFS)
Issued at 1243 PM CDT Sun May 10 2026

Currently VFR across all sites early this afternoon. We are still
expecting a line of TSRA to develop by 22Z-23Z this afternoon,
then move southeast affecting all sites between 22Z and 04Z this
evening, and have kept the TEMPO groups with the same timing from
the previous set of TAFs. Once these storms move through, winds
will shift to the northeast between 10 and 15 knots. MVFR CIGs
will also develop from north to south across the area between 00Z
and 06Z tonight, eventually affecting all sites through most of
the morning hours Monday.
