.KEY MESSAGES... 

- Following a lull in rain chances during the daytime, additional
  thunderstorms will spread into the area Wednesday night into
  Thursday.

  through the weekend and into early next week. Locally heavy rain
  is possible, with a low potential for strong or severe
  thunderstorms.

.SHORT TERM...
(This afternoon through Thursday)
Issued at 1140 AM CDT Wed May 20 2026

North Central Texas currently lies between upper level systems, 
with weak subsidence providing a lull in precipitation across our 
immediate area. The next weather system is not far off, however, 
as an upstream shortwave trough over New Mexico is already kicking
off an axis of convection across the high plains of West Texas. 
This system will move eastward over the next 12-24 hours, 
providing the stimulus for additional scattered to numerous 
showers and thunderstorms across all of North and Central Texas on
Thursday. 

Using a blend of ensemble guidance and short-term model solutions,
introduced low PoPs across our Western North Texas and Central 
Texas counties as early as late afternoon today, with scattered, 
mostly light, activity expected to spread eastward through the 
I-35 corridor after midnight tonight. In response to intensifying 
lift from the arriving shortwave trough, precipitation coverage 
will ramp up in our western zones by daybreak Thursday, expanding 
eastward across all of North Central Texas by midday and early 
afternoon. While this will NOT be an all day rain event, most 
locations should experience at least one quarter to one half inch 
amounts by late afternoon, with a few spots seeing one to two 
inches with the stronger thunderstorms. 

Daytime temperatures today and Thursday will remain below seasonal
norms for late May, with most locations remaining in the 70s both
days. Enjoy the cool, wet weather while you can!

.LONG TERM...
(Thursday night through next Tuesday)
Issued at 1140 AM CDT Wed May 20 2026

The Southern Plains will remain ensconced within a troughy upper 
level flow regime through the weekend and the first half of next 
week. While this won't result in an all out washout, this 
persistent "baggy" pattern will create multiple opportunities for
shower and thunderstorm activity across our forecast area through
next Wednesday. 

After a relative lull in activity on Friday following the exit of
Thursday's shortwave, the next significant opportunity for
precipitation will unfold on Saturday, as another upstream
shortwave trough exits the Rockies and moves into the region.
While guidance diverges somewhat on this scenario, this trough 
will likely slow down over Oklahoma and Texas, and evolve into a
weak closed low by Sunday. Persistent lift and the presence of 
abundant moisture will yield multiple rounds of shower and 
thunderstorm activity across North Central Texas from Saturday 
through Monday. Within this window, the highest confidence for 
precipitation exists from Saturday evening through Sunday 
morning, when lift and moisture convergence appear maximized.

Precipitable water values will be highest in our Central Texas
counties Saturday-Monday, and a low to moderate chance of flash 
flooding exists in this region through this period. At the same
time, the severe thunderstorm potential will be relatively low,
owing to limited instability and shear. That said, some of the
stronger storms through the Memorial Day Weekend will be capable 
of producing frequent lightning, brief gusty winds and small hail.
These hazards will need to be kept in mind when planning outdoor
activities through Monday.  

Extended guidance exhibits limited agreement beyond the weekend. 
However, the continued presence of a mean trough over the Central 
U.S. will lead to an ongoing chance of precipitation across North 
Central Texas from late Monday through Wednesday. Once again, a 
total washout is not expected, but areas of light to moderate 
rainfall will occur through the period. 

The persistent unsettled weather will help retard any major
temperature surges through the middle of next week. Periods of
cloudy weather and rainfall will result in warm, humid days and
mild nights. By and large, afternoon highs will remain in the
lower to middle 80s each day, which is near or slightly below
seasonal norms for late May.

.AVIATION...
(00Z TAFS)
Issued at 634 PM CDT Wed May 20 2026

There is some potential for IFR ceilings to build into TAF sites
periodically after 09Z before scattering out after 18Z.
Probability is too low at this time to include in TAFs (~30-40%
chance of occurrence). TSRA coverage and timing is also fairly
uncertain tomorrow. Have highlighted the most likely time to see
TSRA at terminals with a TEMPO group, and used VCSH to show the
broader time frame in which isolated SHRA/TSRA (20-40% chance) may
be in the vicinity of or at the terminals.
