.KEY MESSAGES...

- Rain chances will continue through Monday with the arrival of a
  weak cold front. A few strong to severe thunderstorms with hail
  and damaging winds are possible later this afternoon and
  evening mainly in North Texas.

- Slightly cooler temperatures with low rain chances will prevail
  through the middle portion of the workweek.

.SHORT TERM...
(This evening through Monday)
Issued at 224 PM CDT Sun Sep 20 2026

The convective setup across North and Central Texas continues to
evolve this early afternoon as a cold front remains well removed
from our area but a shortwave continues to move towards North and
Central Texas. Additionally, a sharp moisture gradient is now
positioned just west of the I-35 corridor with surface dew points
sharply falling as you progress west. This feature is providing a
focus for thunderstorm initiation as temperatures continue to
warm this afternoon.

The shortwave responsible for increasing large-scale ascent is
just now beginning to approach from the west. The overlap of this
forcing with the moisture gradient and strongly unstable airmass
is favorable for additional showers and thunderstorms.

Although overall deep-layer shear remains modest, with the
available instability in place, multi-cell to loosely organized
clusters will be the dominant convective mode this afternoon.
Decently strong surface dew point depressions will increase the
risk for strong to damaging winds with any vigorous convection. A
few instances of hail cannot be ruled out, with expected maximum
hail size closer to 1".

The overall evolution of this afternoon`s convection is somewhat
uncertain. Regardless of the convective development this
afternoon, large scale forcing will remain atop the region through
the night. If the storms this afternoon become cold-pool
dominant, sufficient subsidence may be in place to reduce
tonight`s rain chances. However, if storms remain more
isolated/scattered in nature, another round of showers/storms may
move in from Oklahoma late tonight into early Monday morning.
Given the relative minimum in instability overnight, this activity
is not expected to be severe, however, gusty winds and lightning
will be possible.

The cold front itself will finally begin making more meaningful
southward progress late tonight into Monday. By Monday, the front
and any remnant outflow boundaries should provide more defined
focus for renewed thunderstorm development. Exactly where these
boundaries settle will dictate the corridor of highest rain
chances. At this time, the highest probability of rain tomorrow
will be along and south of the I-20 corridor. Areas along and
south of the front will experience the most unstable air and will
likely see the highest coverage in precipitation. Storm threats
will once again include lightning, gusty winds, and small hail.

Convection should gradually diminish Monday evening as
instability wanes, through isolated showers and storm may linger
near the stalled frontal zone across Central Texas.

.LONG TERM...
(Monday night through next Saturday)
Issued at 224 PM CDT Sun Sep 20 2026

A reinforcing cold front will arrive early Tuesday, helping to
keep temperatures in the lower to mid 90s through much of next
week. The hottest weather will continue to be across the Brazos
Valley, where upper 90s are expected. A few additional showers and
storms will be possible along the boundary in Central Texas,
however, coverage will likely at or below 20%.

Mid-level ridging will gradually rebuild during the middle and
latter portions of the week, resulting in decreasing rain chances
and a slight increase in afternoon temperatures. Highs will remain
in the lower to mid 90s across North Texas with upper 90s in
Central Texas.

.AVIATION...
(18Z TAFS)
Issued at 224 PM CDT Sun Sep 20 2026

Concerns -- Thunderstorms developing west of D10, moving towards
D10 later this afternoon. Gusty and erratic winds possible.

VFR and southerly winds are ongoing at this time across all TAF
sites, however, storms have now developed west of D10 and will
continue moving to the east/northeast. As we continue through the
rest of the afternoon, convective potential within D10 will
increase with storm chances peaking between 00z to 03z. Confidence
in storms impacting any of the North Texas TAF sites has
diminished as the highest likelihood of precipitation is likely to
be just to the north of the terminals. The overall evolution of
this afternoon`s thunderstorm activity will influence any
overnight rain chances as a cold front in Oklahoma generates
additional storms to the north.

The cold front will eventually move through North Texas TAF sites
tomorrow afternoon, bringing weak northerly winds along with a
renewed potential for precipitation. Timing for tomorrow will
continue to be refined as there is still some uncertainty on the
overall placement of the front.

Regardless, expect VFR ceilings to persist through this TAF cycle
given a dry low-level atmosphere in place.
