.KEY MESSAGES...

  for flash flooding to the Brazos Valley Wednesday.

- Elevated fire weather concerns will continue across much of the
  Big Country through the weekend as hot and dry conditions are
  expected to continue.

.SHORT TERM...
(Today and tonight)
Issued at 1246 AM CDT Tue Sep 1 2026

Although another hot summer day is expected across North and
Central Texas with highs in the upper 90s and lower 100s, the
approach of Tropical Storm Edouard will bring low rain chances
(10-30%) to the region this afternoon and evening. There are two
primary reasons for the return of these lower rain chances:

1) The exceptionally moist tropical airmass associated with
Edouard will substantially increase the humidity above the
boundary layer. This will reduce the detrimental effects of
entrainment that has largely inhibited diurnally driven
convection the last month.

2) Forcing for ascent will move in with the approach of Edouard
as the mid-level vort max approaches North and Central Texas from
the southeast. While the amount of lift remains uncertain at this
time, at least weak forcing can be expected by this evening
especially in the vicinity of the Brazos Valley.

Considering the two reasons above, very isolated showers (and
potentially a thunderstorm or two) can be expected across much of
North and Central Texas this afternoon and evening (10-20%
chance). Rain chances will be higher (20-30%) further southeast
into the Brazos Valley in closer proximity to Edouard.

The most likely area to stay dry will be locations west of I-35
and north of I-20. Not only is this area furthest from the
localized lift associated with Edouard, but forecast soundings
continue to show much drier mid and upper-levels that will likely
inhibit the development of diurnally driven convection.

.LONG TERM...
(Wednesday through Monday)
Issued at 1246 AM CDT Tue Sep 1 2026

...Wednesday through Friday...

The expected remnants of Tropical Storm Edouard will slowly work
into the region with scattered showers and thunderstorms (50-70%
chance) possible in Central Texas Wednesday into Thursday. More
isolated coverage of showers and storms is expected across North
Texas during this same time frame. Another day of isolated showers
and thunderstorms (10-30% chance) is possible Friday across North
and Central Texas. Rain chances will again be greatest in Central
Texas.

Temperatures will vary greatly across the region during this time
frame. Temperatures outside of the tropical remnants will
continue to climb into the upper-90s and lower-100s each day. The
most likely area to see these temperatures will be along and north
of I-20, and west of I-35. In this area, fire weather concerns
will continue with afternoon RH values continuing to drop into the
25-40% range and little to no rain expected into the weekend.
Further southeast into the Brazos Valley, highs on Wednesday may
not break out of the 80s. As the remnants of Edouard slowly
dissipate the latter half of this work week, temperatures will be
slow to rebound wherever cloud cover and rain lingers. This will
likely result in highs in the low and mid 90s for much of Central
and Eastern Texas Wednesday through Friday.

Rainfall amounts are expected to be highest south of I-20 and east
of I-35. Rainfall totals through Friday will range from half an
inch to an inch for much of this area. However, localized areas
may see greater rainfall totals than this with locations in the
Brazos Valley potentially seeing 2-3 inches of rain by Friday.
Furthermore, while the severe risk is low, MLCAPE on the order of
1000-2000 J/kg will support a marginal damaging wind risk,
especially for any thunderstorms that can develop in the drier air
on the fringes of the incoming tropical airmass. With locally
enlarged hodographs right near the center of the tropical
remnants, a brief weak spin-up tornado in the Brazos Valley can`t
be ruled out Wednesday as well.

...Saturday through Monday...

The remnants of Tropical Storm Edouard are expected to dissipate
by this weekend. As such, above normal temperatures will return to
the region (especially across North Texas) with highs near or just
above 100 by the start of next week. There will be daily chances
for very isolated showers and storms (10-20%) from the Brazos
Valley into East Texas where moisture is higher. Further north
and west of this area, dry conditions will return as ridging
shifts back east into the Great Plains.

.AVIATION...
(12Z TAFS)
Issued at 523 AM CDT Tue Sep 1 2026

While there is a low chance (10-20%) for isolated showers between
18Z and 01Z today, probabilities are too low to warrant inclusion
in the TAFs. Wind directions at KACT will vary throughout the day
with the approach of Tropical Storm Edouard. As such, have
included FM groups for possible flow changes on runway 1/19. D10
sites are expected to prevail VFR and S/SE flow (120-200) at 5-12
kts for the duration of this forecast period.
