...New UPDATE, AVIATION...

.KEY MESSAGES...

- Scattered storms will continue the rest of this evening before
  dissipating overnight. Frequent lightning and heavy rain will be
  the main threats, but a few instances of severe hail and wind
  are also possible.

- Additional scattered storms are possible on Monday afternoon
  with expected coverage of 20-30%.

- Lower thunderstorm chances exist on Tuesday before more
  widespread storms return by Wednesday.

.UPDATE...
Issued at 552 PM CDT Sun May 24 2026

Scattered thunderstorms have affected much of the I-20 corridor
and surrounding areas this afternoon, and will continue to
progressively redevelop along convective outflows early this
evening. Weak flow/shear continues to support a single-cell
convective mode with threats for mainly sub-severe hail and gusty
downburst winds, but the primary threat is localized flooding due
to rain rates of 1-2 inches per hour. Most of this activity will
wane with loss of heating, with fairly tranquil weather expected
after ~10 PM. A similar pattern will remain in place through
tomorrow with a diffuse upper low circulation overhead and weakly
confluent surface flow near a ill-defined trough axis. This
should support additional scattered shower and thunderstorm
development again on Monday as diurnal destabilization occurs,
and PoPs were raised through the tomorrow afternoon and evening
time period with this forecast update.

.SHORT TERM...
(This afternoon through Monday)
Issued at 1226 PM CDT Sun May 24 2026

Late morning satellite imagery shows generally sunny skies across
the region but a cumulus field has developed over the last hour
from the Metroplex back to the northwest and we`ll monitor its
expansion into the afternoon. The upper pattern features a
notable shortwave trough over southwest Texas within a broader
weakness in the 500 mb heights across the Southern Plains. Mid
level flow is weak, but oriented northwest to southeast which
should place the best vorticity advection and forcing for ascent
to our south through the rest of the afternoon. This generally
doesn`t bode well for storm chances in our area, however the low
level flow is easterly and an earlier morning outflow boundary is
set up near the I-35 corridor which has resulted in a strong but
focused area of low level moisture convergence. Latest aircraft
sounding data indicates a modest capping inversion around 850 mb
which is supported by the latest RAP objective analysis and will
certainly be an inhibiting factor for storm development for a few
hours. However, CAM guidance is insistent on storm development by
mid/late afternoon despite the factors working against it. Given
strong afternoon heating within a very moist boundary layer (90%
mean RH in the lowest 1km - ACARS) featuring very weak low and mid
level flow and a lack of any notable subsidence, we`ll likely
reach convective temps in the mid/upper 80s which should be
sufficient for scattered convection to develop. This is most
likely to occur within the area of focused low level moisture
convergence near or just west of the I-35 corridor from the
Metroplex southwest. Mid level lapse rates >7.5 C/km will be
sufficient to support a few instances of hail or severe wind
gusts via downdraft enhancement from mid/late afternoon into the
early evening hours. Weak steering flow will result in slow moving
storms with potential for locally very heavy rainfall. Coverage
of storms should peak at 30-40% before waning after loss of
daytime heating this evening. Any ongoing convective activity
should quickly diminish after dark with a quiet night expected
across North and Central TX.

The upper trough will slowly drift eastward on Monday which should
result in less potential for storms in our area. The only
exception may be our far eastern counties during the late
afternoon hours where we`ll have 20% PoPs.

.LONG TERM...
(Monday night through next Saturday)
Issued at 1226 PM CDT Sun May 24 2026

Relatively quiet weather will continue Monday night through
Tuesday as North Texas will be on the back side of a departing
trough and too far east of the next approaching disturbance. Warm
and humid conditions will prevail during this time with the
atmosphere ready for additional showers and storms by Tuesday
night. As the upstream trough approaches late Tuesday we should
see scattered showers and storms develop off to our west and move
into North Texas overnight Tuesday night into early Wednesday
morning. We`ll have high PoPs during this time (70-80%) but it`s a
little uncertain whether or not this round of rain/storms will
blast on through and clear things out for Wednesday or not. The
upper shortwave will shear out and elongate over the Southern
Plains which will keep the region within an area of continued
forcing while ample moisture remains in place. This may support
additional shower/storm development through the day Wednesday,
however this is a little uncertain. We`ll likely have some
refinements to the PoP forecast during this time.

Beyond Wednesday, we should see things calm down a bit through the
end of the week but will be watching yet another upstream
disturbance which will likely bring rain chances back to the
region for next weekend.

.AVIATION...
(18Z TAFS)
Issued at 552 PM CDT Sun May 24 2026

Convection will continue in the vicinity of TAF sites through
roughly 01z before activity gradually ends around sunset with
loss of heating. While winds are currently highly erratic due to
effects of convective outflows, they should recover to light
easterly/southeasterly late tonight at speeds at 5 kts or less.
Additional scattered convection can be expected tomorrow
afternoon, and will introduce a short VCTS mention to account for
the possibility of nearby thunderstorms after ~20z.
