.KEY MESSAGES...
- Warm days and mild nights continue through early next week.
- Isolated rains may return near the Coastal Plains this weekend
  into early next week.
&&
.SHORT TERM (THROUGH THURSDAY NIGHT)...
A mid level shortwave and associated thin band of very light rain
will exit to our east this morning. Radar returns have been on the
decline over the last few hours as dry lower levels take their toll.
Only trace amounts are now possible until it exits.
Lower to mid level ridging will resume today and continue for the
next few days. After a slight "cooling" of high temperatures Monday
due to the thick cirrus, mostly clear skies will allow for a return
of high temperatures around 5 degrees above late September into
early October averages while lows remain closer to average.
&&
.LONG TERM (FRIDAY THROUGH MONDAY)...
Mid level ridging remains over our area this weekend into next week.
However, mid level troughing moving over the western states induces
surface pressure falls in the Plains. This allows a moister lower
level airmass to slowly spread into our area. This may result in
slight chances of showers and perhaps a thunderstorm or two each
afternoon into early evening due to the seabreeze primarily over
Lavaca and De Witt counties this weekend, then possibly approaching
the I-35 corridor by the middle of next week. Daily temperature
ranges shrink due to the increased moisture, however both highs and
lows will remain above average.
&&
.AVIATION (12Z TUESDAY THROUGH WEDNESDAY)...
VFR conditions through the TAF period. High clouds are exiting
east of the region early this morning with mainly clear skies
through the day. Variable winds less than 5 KT early this
morning, becoming NE to E around 5 KT this afternoon for most
locations, SE along the Rio Grande.
&&
.FIRE WEATHER...
With minimum humidities in the 20s and 30s each day under ample
sunshine, vegetation will continue to dry. Although wind speeds
should be 10 mph or less, the drying conditions will make the
environment more vulnerable to fire starts.
