SHORT TERM...
(Tonight and Wednesday)

Temperatures at mid-afternoon are 8-15 degrees cooler than
yesterday at this time, across most of our area. Diminishing north
winds will become light by this evening, as surface high pressure
settles southeast across our area. This surface high will shift
out of our area and into South Texas by late tonight, and south-
southwest winds will develop overnight across the Big Country and
Concho Valley areas. Expect enough of a wind speed increase to
limit the extent of radiational cooling across the northern third
of our area. Going with lows in the mid to upper 30s across that
area. For the southern part of our area, ideal radiational cooling
will allow temperatures to drop into mostly the upper 20s for
lows, as winds stay light. A few mid 20s are possible in the more
favored low-lying areas.

With mostly sunny skies and increasing south-southwest winds on
Wednesday, temperatures will rebound into the upper 60s to lower
70s for afternoon highs. Should see some patchy high clouds stream
over the area on Wednesday, associated with subtropical branch of
the upper jet.

LONG TERM...
(Wednesday Night through Tuesday)

After the warm Wednesday, another cold front will move across
West Central Texas Wednesday Night and bring temperatures closer
to normal for Thursday. Meanwhile, a developing upper level trough
will move into the Southern Rockies and close off by Friday.
Models develop a little more convective activity across South
Texas for Friday and Saturday, and try to inch it as far north as
the Hill Country. At this point, will keep most areas dry, but
will include a few showers and storms into portions of San Saba
County. Otherwise, dry conditions to continue.

Temperatures will remain near or a little above normal for the
weekend and into next week, with highs in the 50s/60s with lows in
the 30s/40s.
