.KEY MESSAGES...
- Daytime temperatures remain above normal through the weekend
  and next week.
- Low chances of showers and storms along the Rio Grande Sunday.
&&
.SHORT TERM (THROUGH MONDAY)...
Weak surface high pressure and ridging aloft are combining to
maintain quiet and warm weather today across South-Central Texas. A
few of the hi-res CAMs suggest a few showers are possible over the
Coastal Plains and I-35 corridor late afternoon and early evening,
but any rain will likely be brief. An upper-level trough axis is
currently moving across the Rockies and is expected to move over the
Texas Panhandle tonight, helping to generate some showers and
storms. Most of this activity will occur to our west and weaken as
it encounters the drier air aloft over our area, but a few isolated
showers and storms could reach the southern Edwards Plateau and Rio
Grande Sunday morning, with some development Sunday afternoon within
a residual corridor of modest instability. After being squeezed
slightly by the passing trough, the ridge restrengthens Monday over
northern Mexico and mutes the rain chances for our area. Skies will
be mostly clear in the short term, though there could be plenty of
cirrus on Sunday as the upper trough swings by. Above average highs
in the mid 90s and mild but near average lows in the mid 60s to low
70s are forecast through Monday and through the week.
&&
.LONG TERM (MONDAY NIGHT THROUGH SATURDAY)...
Steady weather is forecast for next week as ridging persists over
our area. Highs and lows look to have only minor day-to-day
variation, maintaining above average warmth in the daytime and
average mildness at night. The ridge does weaken slightly Wednesday
through Friday as an upper trough passes by well to our north over
the Central and Northern Plains. This slightly nudges the chance of
an isolated afternoon shower upwards mainly over the Coastal Plains
and Rio Grande Plains on those days, but generally dry conditions
look to prevail for most.
&&
.AVIATION (17Z SATURDAY THROUGH SUNDAY)...
MVFR ceilings continue to lift and scatter this afternoon with VFR
conditions expected through tonight. Went with a persistence
forecast for low clouds with MVFR ceilings returning to KDRT at 09Z
with TEMPO MVFR ceilings at SAT/SSF beginning at the same time.
Southeasterly wind is forecast this afternoon with some occasional
gusts up to 15-20 knots. Light wind returns overnight at I-35
terminals.
