.SHORT TERM...
(This evening and tonight)
Issued at 108 PM CDT Tue Mar 10 2026

Severe weather potential is still fairly high across West Central
Texas as a potent upper level system approaches. Latest CAMs
continue the trend of a dryline approaching the western border of
the area by mid/late afternoon. Cape values expected to increase
to 2000j/kg or more, with plenty of shear provided by the upper
system. CAMs show rapid convective initiation developing across
the southwest portions of the area and spreading northeast. These
storms may rapidly become severe. SPC has this well covered and
not going to rehash at this point. Forcing increases as the
pacific front overtakes the dryline and the storms may transition
into a line and sweep across the Heartland and Hill Country.

Will want to keep an eye on the southeast portions of the area
this evening once the low level jet begins to redevelop. If the
transition to a line hasn't happened yet and storms are still
discrete, the potential for an increase in tornado potential may
exist.

Also want to keep an eye on the Hill Country and Heartland for
heavy rainfall potential. Latest HRRR lingers the heavy rainfall
across areas like San Saba, Brady, and Junction as the low level
jet expands the rainfall back to the northwest. Movement of the
squall line may be fast enough to prevent this from happening, but
if its not then rain totals may add up fast over there in some
locations.

.LONG TERM...
(Wednesday through next Tuesday)
Issued at 127 PM CDT Tue Mar 10 2026

...Turning Windy and Cooler Wednesday...

A cold front with strong north winds will move into the Big Country
mid/late morning Wednesday and early afternoon across the rest of
West Central Texas, bringing windy conditions. North winds will
likely reach wind advisory speeds in the Big Country in the
afternoon, with gusts of 40 to 45 mph. Will not put out wind
advisory at this time, but let the next shift monitor for its
inclusion, after tonight's severe weather.

While rain chances were left out Wednesday, there is a non zero
chance of a sprinkle or shower, in Heartland...Mcculloch, San
Saba, Brown, Mason counties...as the upper low moves overhead.

Weakening winds and clearing skies Wednesday night, will bring
cooler temperatures, with lows of 35 to 40 degrees expected, The
coldest readings will be in Haskell and Throckmorton counties, where
winds will be lightest.

Much warmer temperatures expected by Friday and Saturday, with highs
potentially reaching 90 degrees Saturday. Windy on Sunday with
another cold front, and will be monitoring Monday and Tuesday
mornings for the potential for a brief light freeze, particularly in
low lying areas.

.AVIATION...
(18Z TAFS)
Issued at 1219 PM CDT Tue Mar 10 2026

MVFR cigs persisting across the southeast terminals of KBBD and
KJCT early this afternoon, but should be breaking up and lifting
during the early afternoon hours. After that, the significant severe
storm potential is the bigger concern. Used the latest hi res
CAMs for the first guess on storm timing across the area but fully
anticipate updates will be needed once the storms eventually
develop.

Dryline/pacific front will push across the area and take the
storms with it later tonight, with much stronger wind speeds
moving into the area late tomorrow morning into the afternoon
hours. Still some uncertainty on timing so did not include in the
forecast yet, but will need to be included in later forecasts.
