Area Forecast Discussion...UPDATED
National Weather Service Austin/San Antonio TX
1138 AM CDT Thu Apr 18 2019

.UPDATE...
We have updated the forecast to lower the expected high temperatures
slightly for areas generally north of the I-10 corridor. Cloud cover
wrapping around the back side of an upper trough over central and
east Texas should help keep temperatures a little cooler than
previously anticipated. We also removed the mention of precipitation
for areas east of Highway 77. Otherwise, no significant changes have
been made to the forecast.

.PREV DISCUSSION... /ISSUED 646 AM CDT Thu Apr 18 2019/

AVIATION...
TSRA has cleared the terminals this morning, leaving a light and
variable wind field in its wake and temporary MVFR ceilings at
AUS/SAT/SSF. Expect these ceilings to linger through 13-14Z as winds
become westerly behind a cold front, further veering after 16Z to
the northwest around 15 knots with stronger gusts near 25 knots. A
scattered cumulus field between FL035-050 may be able to develop
during the day which may inhibit mixing potential for AUS/SAT/SSF,
but expect DRT to remain SKC. Northwest winds will fall below 10
knots after sunset.

SHORT TERM (Today through Friday)...
A line of thunderstorms along the leading edge of a cold front
continues east and will clear the area by 4am. Ongoing showers with
isolated thunder behind the front will continue over the next
several hours before clearing later this morning. By afternoon, drier
air will be filtering in leading to mostly clear skies. Temperatures
will stay pleasant in the mid to upper 70s and low 80s. Gusty northwest
winds will begin to strengthen this afternoon. Areas that could see
a wind advisory will be Rio Grande and Edwards Plateau. These areas
will also experience elevated to near critical fire weather
conditions, as the relative humidities will drop with this drier
airmass. As the trough continues eastward, northerly flow will help
extend pleasant conditions across South Central Texas on Friday.

LONG TERM (Friday Night through Wednesday)...
The weekend starts out clear and warmer as high pressure ridging
moves through. Southerly winds return Saturday, increasing moisture
through at least Tuesday. Saturday also starts a warming trend with
temperatures getting back up into the mid and upper 80s by Sunday.
The next system moves into the Southern Plains Tuesday. This will
again increase rain chances for Tuesday and Wednesday with another
cold frontal passage.
