.SHORT TERM...
(This evening through Tuesday night)
Issued at 1257 PM CDT Mon Oct 12 2026

Low-level moisture transport is in full swing this afternoon as flow
around a high-pressure system over the northern Gulf Coast pulls
moisture-rich air into North and Central Texas. Parts of Central TX
and the Brazos Valley have a 20-30% chance of isolated to scattered
showers and storms during peak heating this afternoon as a result of
this favorable moisture influx. With low clouds still present across
most of North and Central TX, high temps have the potential to
underperform expectations in localized spots; however, most will
still reach the upper 80s to low 90s today.

Tomorrow`s setup is very similar to today, except with even higher
surface dewpoints, pushing afternoon heat index values to near 100
degrees areawide. Isolated to scattered storms have a 20-30%
chance of developing again tomorrow afternoon in Central TX east
of I-35, where the best moisture will reside.

.LONG TERM...
(Wednesday through Sunday)
Issued at 306 AM CDT Mon Oct 12 2026

While still a complicated forecast, the global models have come
into slightly better agreement regarding the evolution of the
western CONUS trough mid-to-late week.

On Wednesday, southwesterly southern stream flow will accelerate
ahead of the closed upper-level low which is progged to be located
somewhere in the Four-Corners vicinity. Adequate height
falls/synoptic ascent should remain largely northwest of the area,
with any appreciable jet streak dynamics remaining confined
closer to the center of circulation. The QPF signal follows suite,
remaining northwest of the area through Wednesday. That being
said, additional WAA-driven showers will be possible through peak
heating on Wednesday. Tuesday`s heat now looks likely to linger
into Wednesday, with heat indices once again pushing the triple
digit mark.

To the east of the trough, a frontal boundary left behind by a
surface low traversing the northeastern CONUS Tuesday into
Wednesday will be draped from the central High Plains through the
Great Lakes. A shortwave will dive south out of Canada sometime
late week, with an associated surface low forcing the residual
frontal boundary south as a cold front. This looks to occur
sometime Friday, bringing precipitation chances with it as it
traverses the region. In its wake, temperatures will drop off
rather dramatically compared to what we`re having to deal with
early this week. As it stands, highs this weekend will top out in
the 70s, with lows dropping into the 50s.

.AVIATION...
(18Z TAFS)
Issued at 1257 PM CDT Mon Oct 12 2026

The broken MVFR deck over North and Central TX has begun to scatter
out from west to east this afternoon across the Metroplex. VFR
should return within the hour at Metroplex sites and around 20Z at
KACT. Southerly winds of 10-15 KT with occasional gusts as high
as 25 KT will continue today; gusts will subside after sunset
before returning late tomorrow morning. KACT has a ~20% chance of
seeing an isolated shower or thunderstorm this afternoon, but the
low probability precludes a mention in the 18Z TAF. MVFR cigs will
return to all sites late tonight and likely won`t improve to VFR
until near the end of the regular TAF period.
