(Tonight and Friday)
Near to slightly above normal temperatures are forecast through the
next 24 hours. An upper level ridge will remain centered across the
lower Mississippi Valley, with its influence extending well into
Texas. Scattered showers and thunderstorms are once again forecast
to develop across portions of West Texas and eastern New Mexico late
this afternoon and early this evening. Most of this activity is
forecast to remain west of West Central Texas, but isolated showers
and thunderstorms were included for western Portions of Crockett
County. Overnight lows will generally be in the lower to mid 70s.
High temperatures on Friday will range from the upper 90s across
much of the Big Country and Heartland, to the mid 90s elsewhere.
(Friday night through next Thursday)
A large upper high will be centered over the lower and middle
Mississippi Valley this weekend through early next week, with a
short wave trough lifting north across the central and northern
Rockies over the weekend. Some convective development will be
possible across far west Texas this weekend where stronger southwest
flow aloft exists, but here in West Central Texas dry conditions
will continue with slightly above normal temperatures continuing.
Models show an upper level trough moving across the Rockies and
into the central and northern Plains Tuesday through Thursday of
next week. This system may drive a weak front in from the north
next Wednesday or Thursday and bring a chance for showers and
thunderstorms to portions of the forecast area. Model confidence
regarding this scenario remains low at this time, so will maintain
a dry forecast through the extended period for now.
