/Today and Tonight/
An upper trough will amplify across the Rockies today and move
across the Plains late tonight and Thursday. A weak surface
trough/dryline will remain just west of the area today and will
be a focus for possible thunderstorm development by late afternoon.
Convergence along this feature will be rather weak but strong
insolation may weaken the CAP sufficiently for a few storms to
develop through early evening. Additional showers and thunderstorms
may develop farther north into the Big Country overnight as support
aloft increases with the approaching upper trough and associated
right entrance region of a 95+ KT upper jet streak. If storms
develop, a few may become strong through the evening hours, with
marginally severe hail possible. Kept POPs at 20 percent for the
overnight hours, with the best chance for rainfall across the
Above normal temperatures will continue today with afternoon highs
90 to 95 degrees. It will also be breezy again today with south
winds 10 to 20 mph, with a few higher gusts. Lows tonight will be
in the lower 70s.
/Thursday through Tuesday/
A potent upper level trough will move across the Plains Thursday,
sending a cold front through West Central Texas. The front is
forecast to move through the Big Country during the early afternoon
hours, and approach the Interstate 20 corridor by early evening. A
moderately unstable atmosphere will reside ahead of the front,
especially across the eastern half of the area. Isolated to
scattered showers are forecast to develop along the front, mainly
during the late afternoon/evening hours. The best chance of
convection will be southeast of a Brownwood...to Menard...to
Junction line. A few storms could become strong to severe, although
widespread severe weather is not anticipated. The front will quickly
move south of the area by mid to late evening, with drier air
filtering in behind it.
Cooler temperatures are forecast behind the aforementioned cold
front. Highs on Friday and Saturday will be in the lower to mid 80s,
with overnight lows in the 50s. A steady warm up will ensue from
Sunday through the middle of next week. Highs will generally be in
the mid to upper 80s, with overnight lows in the 60s. Rain chances
look minimal through at least the middle of next week.
