SHORT TERM...
(Tonight and Wednesday)

The upper high will build tonight and Wednesday over eastern New
Mexico, northwest Texas and Oklahoma. With building heights aloft
and increasing subsidence, rain chances across our area will be on
a diminishing trend. A decent cu field across the area this
afternoon due to abundant boundary layer moisture and weak
instability. Can not rule out and isolated shower or storm.
Otherwise, going with a dry forecast the next 24 hours. Lows
tonight will be 70 to 75 and highs Wednesday will be in the mid to
upper 90s, with possibly a few locations reaching 100.

LONG TERM...
(Wednesday night through Tuesday)

Upper level high pressure over the Southern Plains will continue
to keep west central Texas in a predominantly dry pattern through
the remainder of the week. With dry conditions and plenty of
sunshine, high temperatures will climb into the upper 90s to
around 100 each afternoon especially across the Concho Valley and
Big Country.

The center of the aforementioned high pressure shifts to the west
of the region this weekend resulting in northwesterly flow aloft.
Both the GFS and ECMWF continue to indicate disturbances rotating
around the ridge resulting in increasing rain chances for the
latter half of the weekend and going into early next week. The
increasing cloud cover and precipitation will result in cooler
temperatures for the early part of next week.
