.SHORT TERM...
(This afternoon through Sunday)
Issued at 1125 AM CDT Sat Sep 19 2026
High pressure, centered atop North and Central Texas, will once
again lead to well above normal temperatures throughout the
region this afternoon. Although the area of high pressure has
remained nearly stationary over our region, heights have gradually
been on a downward trend resulting in sub-100 degree weather
across a large part of the region. Today`s weather should be no
different as the ridge continues to weaken, evident by the 4dm
decrease of the 500mb heights over the last 24 hours.
Effective low-level mixing will keep afternoon heat index values
at or slightly below actual temperature, preventing the need for
any heat-related products. Unfortunately, effective low-level
mixing will result in afternoon minimum relative humidity between
25-35%. The threat for additional grass fires will increase this
afternoon as winds pick up between 10-15 mph. For that reason, a
Grass Fire Danger Statement has been issued for this afternoon.
Overnight, tranquil weather conditions are expected to continue with
southerly flow in place. Temperatures tonight will be in the
lower to mid 70s across much of the region with the exception of
the DFW Metroplex, where upper 70s will prevail.

.LONG TERM...
(Sunday night through next Friday)
Issued at 1125 AM CDT Sat Sep 19 2026
A pattern change will commence on Sunday as shortwaves move from
west to east across the Central Plains. A cold front will move
south into Oklahoma, stalling along the I-40 corridor. A weakly
defined surface low may also develop through the day, aiding in
northward moisture transport across the region. With the area of
high pressure shunted south, subsidence will be on the downward
trend, allowing for a few isolated mid-day showers west of I-35.
By the afternoon, a trough axis will progress westward with
embedded shortwaves adding mid-level forcing for ascent. As
instability increases, scattered thunderstorms are looking
probable just west/northwest of our region. With general storm
motion expected to be south to south/southeast, this activity
will likely work its way into our region by late in the afternoon
and evening hours. The thermodynamic environment will become
favorable for a few strong to severe storms capable of producing
isolated damaging winds and hail. The greatest coverage of
precipitation will remain along and west of I-35. With the stalled
front nearby and the shortwave still overhead, convection may
persist overnight and into early Monday morning, however, the overall
severe weather threat decreases overnight.
On Monday, the frontal boundary will remain stalled across the
region, leading to additional showers and storms in the afternoon.
Exact location of where the storms may develop remains uncertain
and will vary on the placement of outflows. However, there will be
a potential for strong winds with any storm that develops given
the continued warm weather and dry near-surface air.
A shallow front may move into North Texas on Tuesday, helping to
maintain a low probability of precipitation generally west of
I-35. This front will once again lack significantly cooler air as
post-frontal temperatures will still be in the 90s across the
region.
By Thursday, ridging will once again begin to build across the
Southern Plains, deflecting any shortwaves away from the region
and reducing our rain chances to near 0%. This also means we will
begin to see an upward trend in afternoon temperatures as highs
return to the mid to upper 90s with overnight lows remaining in
the lower to mid 70s.

.AVIATION...
(18Z TAFS)
Issued at 1125 AM CDT Sat Sep 19 2026
Southerly winds continue across all of North and Central Texas
with fair weather cumulus clouds developing this afternoon. No
major weather concerns are expected today given skies will remain
VFR with no significant wind changes.
The benign weather will persist through tomorrow morning before an
increase in showers and storms commences late in the afternoon.
Storms may develop west of D10 between 21-00z, then gradually
shift east through the rest of the evening. This is just outside
of the KDFW extended TAF, therefore, no mention of precipitation
will be added with this package. This will continue to be
monitored and a mention of precipitation may be needed in
subsequent TAF packages.
