...New UPDATE, AVIATION...
.KEY MESSAGES...
- Scattered showers and thunderstorms will affect much of the area
through Tuesday with primarily a threat for flash flooding. A
few storms may also produce strong downburst winds and hail.
- Seasonably hot and rain-free weather will resume late in the
week, with highs returning to the upper 90s.

.UPDATE...
Issued at 711 PM CDT Sun Jul 12 2026
Latest radar imagery shows scattered showers and thunderstorms
continue to sink slowly southward across North Texas this evening
with a few more isolated storms in Central Texas. Current storms
are expected to diminish later this evening, but additional storms
will likely develop overnight into Monday morning across North
Texas then move southward and expand across Central Texas during
the day. Have adjusted pops downward towards the Red River
overnight/tomorrow based on this thinking which is in line with
latest CAM guidance.

.SHORT TERM...
(This evening through Monday)
Issued at 140 PM CDT Sun Jul 12 2026
A humid, weak-flow convective regime is now underway across North
and Central Texas. The remnants of the overnight Oklahoma complex
persist across southwest Oklahoma, while isolated to widely
scattered showers and storms have developed along the outflow
boundary near the Red River and within the deeper moisture across
East Texas. Convective overturning across North Texas was minimal
this morning, and cloud cover scattered quickly enough to allow
moderately instability to develop. Coverage should continue to
increase through the afternoon as heating acts on the existing
boundaries, though the episodic and scattered nature of the
activity means not everyone will receive rain. Locally heavy
rainfall will be the primary concern, with isolated gusts above 40
mph possible where stronger cores collapse.
This morning`s Fort Worth sounding sampled a PW value near 2
inches, which is above the 90th percentile for mid-July and
approaching the upper end of local climatology. Combined with weak
flow through much of the column, this environment will favor slow
or erratic storm motions and cell mergers. The environment has
already demonstrated its ability to support high rainfall rates (2
to 2.5 inches in an hour in parts of OK this morning), so even
loosely organized convection may become hydrologically
significant. Rainfall totals will likely be highly uneven, but a
few locations could receive several inches in a short period,
especially in urban areas, poor-drainage locations, or where
storms repeatedly affect the same corridor.
The heavy rain concern will increase Monday as the weak boundary
settles farther south and the easterly disturbance shifts westward
across the state. Increasing southerly flow near the surface will
continue feeding tropical moisture into the region, while weak
steering flow persists aloft. Storms may continue redeveloping on
the inflow side of existing clusters, allowing several rounds of
heavy rain to affect the same corridor. This favors training and
backbuilding from roughly the I-20 corridor southward, including
much of the DFW Metroplex and Central Texas, though the exact axis
will depend on where todays convection leaves behind the most
persistent boundaries. Clouds, rain, and outflows should hold
Monday highs mainly in the upper 80s and lower 90s.

.LONG TERM...
(Monday night through next Saturday)
Issued at 140 PM CDT Sun Jul 12 2026
The better heavy-rain signal should continue shifting into
Central Texas Monday night and Tuesday as the easterly wave moves
southwestward beneath the ridge that is centered well north of the
region. Deep moisture, weak mean flow, and residual boundaries
will support additional rounds of showers and thunderstorms, with
the greatest flooding concern across Central Texas and the Brazos
Valley, including the Waco area. The most vulnerable locations
will be those that receive meaningful rain beforehand, since
another round over the same corridor could quickly overwhelm urban
drainage or other flood-prone areas.
Confidence remains lower in the placement and duration of the
heaviest rain than in the overall pattern. Recent model runs have
struggled with both the timing and location of ongoing
convection, and any forecast training axis will depend heavily on
boundaries that may not become apparent until storms are already
underway. Rain chances should gradually contract south and west
Tuesday night into Wednesday as the disturbance continues toward
West Texas, though a slower progression would keep meaningful
precipitation chances in Central Texas longer. Ridging and
subsidence should strengthen during the latter half of the week,
bringing decreasing storm coverage and a return to hotter
conditions, with highs climbing back into the upper 90s by late
week.

.AVIATION...
(00Z TAFS)
Issued at 711 PM CDT Sun Jul 12 2026
Outflow boundary with widely scattered SHRA/TSRA continues moving
through D10 this hour with majority of activity now south of
terminals. Wind gusts mostly in the 25-35 kt range were observed
with the outflow boundary, but winds will subside over the next
hour or two while becoming more easterly. Overnight, additional
SHRA/TSRA with MVFR conditions are likely to develop in D10 in
the 10-14Z timeframe then move southward out of D10 after 14Z,
although due to uncertainty on coverage will keep mention at just
VCTS for now. At ACT, current activity in D10 is likely to
dissipate before reaching the airport this evening and only have a
PROB30 mention for SHRA. TSRA are more likely at ACT on Monday
morning/afternoon with MVFR conditions and gusty winds up to 30
knots.
