.SHORT TERM...
(This evening through Monday)
Issued at 207 PM CDT Sun Jun 14 2026

Early this afternoon a cold front has moved through most of the Big
Country and is moving south into the Concho Valley and Heartland.
Isolated to scattered showers and thunderstorms are occurring ahead
of the front. Expect an increase in this activity as the front
continues to slowly progress south. The main concern will be locally
heavy rainfall as precipitable water (PWAT) values this afternoon
are in the 1.5 to 2 inch range and are forecast to increase to 2
inches or higher across much of the southern half of the area
tonight into Monday morning. This activity will likely be slow
moving so heavy rainfall will likely result in flooding, especially
across low-lying areas and roads. Given these factors, have issued a
Flood Watch for southern portions of the area from this afternoon
through Monday evening. This is one of those setups where not
everyone in the watch will see locally heavy rainfall and flooding,
but given the high PWAT values and slow moving storms, we do expect
locations within the watch to see high rain amounts. The highest
flooding threat will likely be closer to I-10, but the potential is
there farther north, so have included the Concho Valley in the watch
as well. Medium to high rain (40-80%) rain chances are forecast
overnight, with the highest rain chances across the southern half of
the area. The front is forecast to then stall just south of the area
on Monday. Additional isolated to scattered showers and
thunderstorms are possible behind the front on Monday. Again, the
highest rain chances are across the southern half of the area and
locally heavy rainfall will be possible. Much cooler temperatures
are forecast on Monday with highs in the upper 70s to mid 80s. Rain
chances will quickly end by late Monday. Overnight lows will be in
the mid to upper 60s.

.LONG TERM...
(Monday night through next Sunday)
Issued at 207 PM CDT Sun Jun 14 2026

Highs on Tuesday will be back to near seasonal normals, in the upper
80s to lower 90s. An upper level ridge across northern Mexico and
the Desert Southwest will result in a return of above temperatures
Wednesday and Thursday. As mentioned yesterday, an upper level low
will be centered across South Texas Tuesday. This feature will then
track northeast toward Southeast Texas Wednesday into Thursday. The
lower heights associated with this feature will result in
temperatures that are less hot than originally forecast.
Temperatures on Wednesday will still be hot, especially across our
western counties where highs will be between 100 and 104. Mid to
upper 90s are forecast elsewhere. A bit more uncertainty arises on
Thursday. The GFS has consistently been indicating a cold front
moving through the area late in the day Thursday. This results in
compressional heating ahead of the front with highs exceeding 100
degrees, especially across the southern half of the area. The ECMWF
is much weaker with any front and indicates a slower solution with
the upper level low. The current forecast shows highs in the mid 90s
to near 102, but these may need to be nudged a bit if the GFS
solution begins to look more likely.

The next concern is rain chances late Thursday into Saturday. The
GFS continues to be more aggressive with any showers and
thunderstorms across the area during this time frame, versus the
drier ECMWF. The GFS develops a weak low pressure across the area and
this in combination with the weak front in the region, results in
shower and thunderstorm activity. For now, PoPs were kept in the low
to medium (20-40%) range, but these are likely to change. Highs on
Friday will less hot, generally in the low to mid 90s.

(00Z TAFS)
Issued at 638 PM CDT Sun Jun 14 2026

A weak cold front, currently passing through KSJT will drift
slowly south and exit the I-10 corridor by late evening. Scattered
to numerous showers and thunderstorms are expected primarily south
of I-20 this and evening, then mainly across the far southern
terminals overnight. Stratus will develop by late this evening
and overnight, with ceilings initially MVFR but lowering to IFR
during the pre-dawn hours. Some reduction to visibility is also
expected but should remain in the 3-5SM range. Ceilings are
expected to lift to MVFR again by late morning/early afternoon and
persist through the afternoon hours. winds will remain light
northeasterly through the forecast period.
