.SHORT TERM...
(This evening through Tuesday)
Issued at 1228 PM CDT Mon May 25 2026
Afternoon visible satellite imagery shows an expanding cumulus
field across North and Central TX and radar is detecting a few
isolated storms at this hour. The region remains under the
influence of a slow moving upper trough with weak vertical wind
shear and a moist boundary layer resulting in modest instability.
Satellite imagery suggests that at least some weak subsidence is
occurring across our southwest counties in the wake of earlier
convection, but this should quickly erode with strong afternoon
heating. An ACARS sounding from about 30 mins ago indicates
negligible capping and low level moisture convergence has
increased over the last hour, particularly along and east of I-35.
As a result we should see scattered showers and thunderstorms
increase in coverage through the afternoon hours. Similar to
yesterday, very weak low and mid level wind fields will promote
nearly vertical updraft development with initial storm motions
less than 5 kt. Coverage of storms will be heavily dependent upon
boundary interaction once this initial activity starts to collapse
and downdrafts spread out. We`ll have PoPs at 20-30% areawide
with the initial favored area for development east of I-35 and
south of I-20. Storm motions will be erratic with new updrafts
propagating in the direction of low level boundary collisions.
GOES estimated PW values >1.5", weak steering flow, and modest
instability suggest that locally heavy rainfall and isolated
instances of flash flooding will be the main threat today. Mid
level lapse rates are weaker than yesterday which should limit
hail potential, but there will certainly be some potential for
isolated severe wind gusts with the strongest storms. This
activity should tend to wane with loss of daytime heating, but the
slow moving upper trough could continue to assist with storm
maintenance after dark.
Most of North Texas should remain quiet overnight tonight, but
there is a chance for additional shower/storm development very
late tonight into Tuesday morning mainly across our northwest
counties. This area will be under the influence of increasing
forcing for ascent from the next upstream trough along with
slightly faster low level flow which should result in some warm
advection convection closer to morning. Otherwise, a broad
weakness in the mid level heights will persist through Tuesday
afternoon across North Texas and we`ll likely see additional
widely scattered showers and thunderstorms. With the upstream
trough approaching Texas during the day, showers and
thunderstorms will become more numerous across the western part of
the state through the afternoon. This activity will spread east
into our area Tuesday night.

.LONG TERM...
(Tuesday night through next Sunday)
Issued at 1228 PM CDT Mon May 25 2026
Showers and thunderstorms will be ongoing to our west Tuesday
night and will overspread the region during the overnight hours.
There is still a little uncertainty as to how organized the
activity will be which will have an impact on coverage in our
area. Model guidance has trended toward a little more storm
organization into Central Texas after midnight which may limit
coverage farther to the north closer to the Red River. The finer
details will be resolved over the next 24 hours, but it`s a good
bet that most areas pick up additional rainfall late Tuesday night
and we`ll have the highest PoPs during this time. Similar to
previous events, Wednesday`s forecast will be dependent upon what
happens late Tuesday night. Right now we think there will be a
lull in storm development early Wednesday in the wake of early
morning convection. However, the upper trough will be slow to
progress eastward and will actually begin to shear apart as it
approaches the I-35 corridor. This would keep persistent large
scale forcing for ascent in place across the region through the
day Wednesday and would likely support additional convective
development. Right now, we`ve got the highest rain chances east of
I-35 during the day Wednesday and have broadly undercut the
guidance PoPs based on the thought that late Tuesday night`s
activity would inhibit further development at least initially.
This may be a little fast though so, adjustments will likely be
needed to Wednesday`s forecast.
The active pattern will continue through the end of the week with
a steady flow of upstream disturbances transiting the Southern
Plains. Storm chances will continue Thursday through Sunday across
all of North and Central TX. The overall severe weather threat
will remain isolated but continued rainfall could support an
increasing flood risk across the region by next weekend.

.AVIATION...
(00Z TAFS)
Issued at 626 PM CDT Mon May 25 2026
North and Central Texas are well into another evening of showers
and storms associated with an upper low positioned directly
overhead. Coverage has remained mostly scattered (much less than
yesterday), and storms appear to already be on a downward trend.
The threat for occasional direct TS impacts has shifted south to
KACT, as the Metroplex has been worked over pretty well from
earlier storms. Ongoing convection west and south of the DFW area
should dissipate 01-03Z this evening, though a few isolated storms
may persist later into the night due to the presence of the upper
low. Recent rain and light winds may lead to patchy fog
development overnight into Tuesday morning. Will keep an eye on
metar trends overnight, but at this time it looks like any
significant visibility reductions will remain in rural locations.
The upper low will lift to the north late tonight and Tuesday as a
shortwave trough approaches from the west. Isolated storms will be
possible northwest of the DFW area Tuesday morning nearest the
upper low. Additional diurnally driven storms will be possible
Tuesday afternoon, which will require VCTS 20-23Z. The shortwave
will bring another round of more widespread showers and storms
around 06Z Tuesday night.
