.SHORT TERM...
(Today and Tonight)

Today and tonight will be the start of a drying period for West
Central Texas. As high pressure continues to build over the region,
skies will gradually clear, from north to south, today and tonight.
Highs today and lows tonight, will be cooler than seasonal normals
for this time of year: mainly 75 to 80 and mid 50s, respectively.
Winds for the next 24 hours will be either light from the north at
10 mph or less, or variable at around 5 mph.

.LONG TERM...
(Wednesday through Monday)

Quiet and dry weather will occur for our area through the end of
this week, with mostly clear skies. As a large upper low moves from
the southern Great Lakes over the Ohio Valley and meanders Wednesday-
Friday, a relatively narrow upper ridge will build over the High
Plains and the western half of Texas. Temperatures will be warmer
Wednesday with highs expected to be mostly in the mid 80s across
our area. As a surface ridge builds south across the Plains, a
cold front will push south into the Big Country (our northern
counties) late Wednesday night, and across the rest of west
central Texas during the day Thursday. Temperatures will be cooler
behind this front, most noticeably across the Big Country. Early
morning lows will be in the mid to upper 50s Thursday, and in the
lower to mid 50s Friday. Pleasant early Fall temperatures are
expected on Friday with highs in the mid to upper 70s.

The flow aloft over Texas will transition from weak ridging aloft to
quasi-zonal during the weekend, as the aforementioned upper low
lifts northeast across the Great Lakes and an upper trough enters
the northwestern CONUS. Southerly winds will return to our area, as
the surface ridge axis shifts east toward the Mississippi Valley
and a lee surface trough develops to our west. A warming trend in
temperatures is expected with readings pretty close to normal.

Rain chances creep back into the forecast early next week with the
forecast approach of a surface trough/dryline into a sufficiently
moist and unstable airmass. Carrying low PoPs for the possibility of
showers and thunderstorms Monday-Tuesday for some of our western and
northwestern counties.
