.KEY MESSAGES...
- Dry conditions the next 7 days with cool mornings and warm
  afternoons
&&
.SHORT TERM (THROUGH SUNDAY)...
Upper level ridging will build into the region today and remain in
place through the weekend, between troughs over the southwest
and southeast U.S. Dry conditions with clear to partly skies are
forecast across south-central Texas. A weak east to southeast
flow resumes this evening into Saturday morning, with a very
shallow moisture return forecast. Despite this, mixing will
allow dew points to bottom out in the 50s Saturday and Sunday
afternoons. Morning low temperatures in the 60s should be
common, but low-lying valleys, especially across the Hill
Country, could dip into the upper 50s. Afternoon highs will
continue to run slightly above average.
&&
.LONG TERM (SUNDAY NIGHT THROUGH THURSDAY)...
The ridge aloft briefly weakens Monday and Tuesday as the southwest
U.S. trough dampens and moves east into the central CONUS. This
could bring a brief increase in mid and high clouds to the
region. South-central Texas will remain in a dry northwest flow
aloft Wednesday through Friday, between a ridge centered over
Mexico and low over the southeast U.S. Continued dry conditions
and slightly warmer temperatures are forecast the latter half
of the week.
&&
.AVIATION (12Z FRIDAY THROUGH SATURDAY)...
VFR flying conditions are expected tonight through Saturday with any
clouds AOA FL060. Light winds will remain mostly NE but could be
shifty with decoupling. NE Winds should pick up to around 5-7 knot
for most areas and maybe turn more due east late in the day, at
least for the I-35 sites. Meanwhile, DRT will make the full
transition to SE winds by midday. Nighttime winds will decouple
again and be shifty with a SW winds expected to develop over
I-35 in the 24-30 hour time-frame.
