.SHORT TERM... /Issued 126 PM CDT Sat Jul 12 2025/
/Today and Tomorrow/

There will be a threat for flooding today, tonight and tomorrow
across portions of North and Central Texas. A Flood Watch is in
effect through tomorrow evening as pockets of 4-5 inches of rain
will be possible within the watch area.

The environment atop North and Central Texas is characterized by
anomalously high moisture content that will be tapped into over
the next 24-36 hours. Precipitable water content was sampled at
1.9" this morning, placing it above the 90th percentile for July
12th. As a shortwave and weak front inch closer to our region,
instability will continue to increase, maxing out near 2000 J/Kg
in the next couple of hours. This should lead to a blossoming of
thunderstorm activity, especially in North Texas. With weak
steering flow in place, environmental shear will remain minimal,
minimizing the threat for severe storms. Having said that, a few
strong storms capable of gusty winds cannot be ruled out.

Heading into the evening hours, the shortwave will continue to
slowly shift southeastward with a vorticity max likely across the
western Central Texas. Dynamic cooling aloft will likely enhance
instability and lead to additional heavy rainfall during the
overnight hours. Short-range models continue to advertise
localized pockets of 4-5 inches of rain somewhere along and south
of I-20 through the overnight period. Confidence in the location
of each individual bullseye remains low, however, there was
enough confidence to expand the watch eastward across Central
Texas. All areas along and west of I-35 should remain vigilant for
night-time flooding.

By sunrise tomorrow, the shortwave will continue to slowly shift
east across North and Central Texas. Scattered showers and
isolated storms will be ongoing with much of the region covered in
a shroud of clouds. A relative minimum in precipitation coverage
is expected tomorrow morning before precipitation coverage
increases in the afternoon once again. With additional bouts of
heavy rain possible during the afternoon hours, there will
continue to be a threat for flash flooding should a storm remain
stationary over a single location.

With southerly flow Sunday night and troughing just to our west,
the potential for showers and isolated storms will remain in place
through Sunday night.

.LONG TERM... /Issued 126 PM CDT Sat Jul 12 2025/
/Monday Onward/

The potential for rain will linger through the day on Monday as
the upper trough begins to drift eastward. By Tuesday, mid-level
heights will begin to increase as the ridge across the SE United
States expands towards our region. This should limit precipitation
chances through the rest of the week.

A slight warming trend is expected the latter half of the week as
temperatures rise into the mid and upper 90s. Heat index values
may approach 105 by next weekend.

.AVIATION... /NEW/
/00z TAFs/

While the D10 airports are in a relative lull in terms of
convective activity as of 23z, additional thunderstorm development
is in progress to the west along an advancing outflow boundary.
New development will be expedited further if this outflow collides
with a second stationary boundary draped across the western
portion of the Metroplex, in which case fairly widespread TSRA
could impact the TAF sites between 01-05z. This may also result in
a temporary northwest wind shift for select D10 airports. It is
possible that this convection lingers along a W-E axis well into
the overnight hours, and perhaps even into Sunday morning.
However, its precise placement remains uncertain, and will be
dictated by small scale features like additional outflow
boundaries. Will maintain VCSH and VCTS through Sunday morning
with low confidence in the precise timing of TSRA impacts. For
Waco, the next round of thunderstorm chances will hold off until
closer to daybreak Sunday, after the ongoing activity nearby
dissipates in the next few hours. Areas outside of convection are
likely to fill in with MVFR stratus tomorrow morning before these
cigs mix out by midday. Late in the morning or early in the
afternoon, am expecting most convective activity to shift
east/southeast of the TAF sites with the upper trough axis. This
should limit convective impacts through most of tomorrow afternoon
and evening aside from perhaps a stray lingering shower or two in
North Texas. Outside of convective influences, a south wind at
8-12 kts will prevail.
