Area Forecast Discussion
National Weather Service Austin/San Antonio TX
303 PM CST Sun Dec 17 2017

.SHORT TERM (Tonight through Monday Night)...
Much of the area will continue under cloudy skies as eastern Pacific
moisture pushes from the southwest into South Central Texas.
Temperatures are expected to remain relative warm this evening and
overnight for the potential of patchy to areas of fog developing
around midnight tonight through about 9 or 10 am Monday. Can`t rule
out some areas with dense fog around dawn. With abundant moisture in
place and an upper level pressure system over the four corners
region late tonight moving slowly to the east and into west Texas,
expect drizzle to light rain across the eastern two-thirds of South
Central Texas Monday morning in addition to foggy conditions.

As the upper system moves to the east throughout the day, scattered
showers and even isolated thunderstorms are expected mainly east of
Highway 83 (east of a Leakey to Carrizo Springs line).

The activity is expected to pick up as well as storm`s intensity
later Monday night into Tuesday as the upper level disturbance moves
into the southern Plains. A low level jet of 40 to 50 knots will
allow storms to quickly develop and become strong to even severe.
Main weather hazard could be damaging gusty winds.

Rainfall amounts for the period could range from one half to an inch
mainly along and east of Highway 77.

.LONG TERM (Tuesday through Sunday)...
The strong to severe weather threat continues for much of Tuesday and
mainly along and east of Highway 77. The upper level disturbance
finally lifts and pushes to the east late Tuesday afternoon with dry
weather conditions and a warmer trend for Wednesday and Thursday.

Chances for rain return on Friday ahead and along a cold front with
rain coming to an end by Friday night. The latest runs of medium-
range models show warmer temperatures and relative dry weather
conditions for next weekend. Still to many model runs to go and
solutions can chance back to earlier solutions. Therefore, continue
to monitor our website for the latest forecast packages as you plan
for the Christmas holiday weekend.
