...New Aviation, Short Term...

.KEY MESSAGES...

- A cold front will bring scattered storms (30-70%) on Saturday.
  A few strong to marginally severe storms are possible, mainly
  along and east of I-35.

- Cooler weather is expected on Sunday, followed by a warm up on
  Monday. A couple weak cold fronts will move through the area
  throughout the week, with mild temperatures expected.

- Low rain chances are set to return late next week.

.SHORT TERM... /NEW/
Update:

What has changed: there is higher confidence in additional
showers and storms behind the front.

Similar to the discussion below, latest guidance continues to
show warm air advection showers in the morning, with more
scattered upscale development occurring along the Pacific front
as it moves east. The storms along and ahead of the Pacific front
will hold our severe threat of damaging winds and large hail,
particularly for areas near and east of I-35. Trailing behind the
surface front is the base of the shortwave trough aloft, which
will move across the region over the afternoon. Looking at
isentropic analysis, there is quite a bit of mid-level lift
associated with this shortwave, and with increased lapse rates and
enough moisture remaining, would allow for post-frontal sub-
severe precipitation to develop as the shortwave passes. The
caveat to this is whether there will be enough moisture left
behind the Pacific front in reality, which will impact coverage
of any development.

Previous Discussion:
/Through Saturday Night/

Another warm and mostly rain-free day is expected across the
region today. High temperatures will peak in the mid 80s to low
90s. Gulf moisture will surge northward today, especially into
Central Texas. This may be able to squeeze out an isolated shower
across Central/Southeast Texas where we`ll advertise 10-15% PoPs
through the afternoon.

On Saturday, a shortwave trough at upper levels will dig into West
Texas during the morning hours, with a pre-frontal trough expected
to set up just west of the CWA. Low-level winds will strengthen during
the early morning hours in response to the approaching shortwave,
which will continue to advect rich Gulf moisture all the way into
North Texas ahead of the approaching system. Warm advection
showers may develop in portions of North Texas (especially western
North Texas) during the morning hours, with showers and
thunderstorms expected to develop west of I-35 by mid to late
morning as both the surface trough and shortwave reach our western
border. This activity will move east through the remainder of the
day, with the best coverage across North and East Texas (50-70%
chance) and scattered coverage across Central Texas (30-40%
chance). We will likely see a more linear structure to storms
rooted along the pre-frontal trough, with more discrete showers
and storms developing ahead (east) of the trough/line of storms
within an area of strong warm advection.

As far as the severe weather threat goes, isolated to scattered
strong to severe storms will be possible along/east of the I-35
corridor, coinciding with an axis of 1500-2500 J/kg of MUCAPE and
around 50-60 knots of deep layer shear. The greatest potential for
severe storms is still expected to be along/east of I-45/US-75
during the afternoon, but there is one caveat. While models are
mostly in agreement on storm timing, a couple of the CAMs are
slightly slower with the shortwave/surface trough. These slower
solutions would result in a slight delay in convective
development, which could allow the instability axis to stretch
further west than currently anticipated. If this occurs, the main
severe weather threat area would shift slightly further west.
Damaging wind gusts and hail will be the primary hazards with any
of this activity. The tornado threat will be low and confined to
far northeastern portions of the forecast area.

Showers and thunderstorms will exit from west to east Saturday
evening, with the arrival of a cold front bringing an end to any
lingering showers or storms overnight. Cooler air will be ushered
in behind the front, with lows falling into the upper 40s to mid
50s across North Texas and mid 50s to low 60s in Central Texas.
Breezy north winds will also develop behind the front, with wind
speeds between 10-15 mph and gusts around 20-25 mph.

.LONG TERM... /Issued 1254 PM CDT Fri Oct 17 2025/
/Sunday Onward/

Cooler, fall-like weather is expected on Sunday in the wake of the
cold front, with high temperatures mostly in the 70s. Despite the
cooler temperatures, low humidity and breezy winds may result in a
slightly elevated fire threat west of I-35 Sunday afternoon,
mainly for any areas that don`t receive rain on Saturday. A cool
night is expected Sunday night, with overnight lows in the upper
40s to mid 50s areawide. Southerly winds will return Sunday
night, with breezy southwest winds expected to develop on Monday
as another cold front approaches from the north. Wind speeds are
expected to be between 10-20 mph, with gusts around 25 to 30 mph.
We`ll see some slight downsloping effects in western North and
Central Texas, thanks to the subtle westerly wind component. This
will result in hot temperatures in the low to mid 90s across
western North and Central Texas, with highs in the mid to upper
80s expected across the rest of the area. Breezy winds, hot
temperatures, and low afternoon humidity (20-35%) will result in
an elevated fire threat west of I-35 Monday afternoon, especially
for any areas that miss out on rain this weekend.

The cold front is slated to arrive in North and Central Texas
Monday night into Tuesday. No rain chances will accompany the
front, as moisture will remain scoured from the region behind the
weekend cold front. Pleasant post-frontal temperatures are
expected on Tuesday, with highs in the mid 70s to mid 80s. A
subtle warming trend is expected Wednesday and Thursday, but
temperatures will remain relatively mild. We`ll likely see
another cold front late in the week, which may be accompanied by a
few showers or storms.

.AVIATION... /NEW/
/00Z TAFs/

Concerns: MVFR cigs near daybreak tomorrow; thunderstorms tomorrow
morning and afternoon at all TAF sites.

Southerly winds will persist overnight, ushering in a blanket of
MVFR stratus from our S-SW. This will impact the morning push, but
will gradually lift throughout the rest of the morning. Out ahead
of an incoming Pacific front, winds will veer more southwesterly
and isolated showers will begin to develop across portions of the
region. The main window of impacts to D10 airport operations will
be between 17-22Z, when the storms that develop along and behind
the front push through, and have introduced TSRA for greatest
impacts between 19-22Z. There is more uncertainty on TSRA impacts
as far south as ACT, so have only prevailed SHRA VCTS between
20-23Z at this time. All activity at the airports should come to
an end between 22-23Z, with rain-free conditions lingering the
rest of the period. Winds will likely return to the southwest for
a few hours, but the true cold front will surge south late
tomorrow night, quickly transitioning winds out of the north near
the end of the extended 30 hour period.
