Area Forecast Discussion
National Weather Service Austin/San Antonio TX
621 AM CDT Tue Sep 4 2018

.AVIATION...
The bulk of the shower and thunderstorm activity remains between the
DRT and San Antonio terminals. Will continue to include the mention
of precip in those TAFs as activity will continue to skirt the
terminals off and on for several more hours. The probabilities for
precip for Austin are still there as some streamer showers are
developing to the south. Will include the mention of VCSH for now and
will amend if necessary. Think we should see a break in the late
morning hours before some redevelopment is possible in the afternoon
hours. Will handle that threat with VCSH for Austin and VCTS for the
San Antonio sites. Tonight should be much more quieter than last
night for the airports, but can't rule out a passing shower or
thunderstorm. Will keep the mention of precip out of the overnight
period. MVFR/IFR ceilings currently in place should lift to VFR by
the early afternoon hours but another round of MVFR is likely
overnight.

&&

.PREV DISCUSSION... /ISSUED 347 AM CDT Tue Sep 4 2018/

SHORT TERM (Today through Wednesday)...
An MCV is over the Rio Grande Plains with a tropical airmass with
PWs of 2 to 2.4 inches over all of South Central Texas and the Hill
Country. Showers and thunderstorms with pockets of heavy rains have
been redeveloping over the last hour or so as the low level jet has
strengthened. This was well indicated in most models and expect this
trend to continue into this morning. These rains are falling over
areas that have received upwards of 4 to 9 inches of rain since
Sunday evening. Have expanded the Flash Flood Watch into the southern
Hill Country and east to the I-37 corridor, including the San Antonio
Metro area and extended it until 1 PM. Expect an additional 2 to 5
inches of rain with isolated spots up to 7 inches. Renewed or
additional flash flooding is likely along with possibly river and
larger stream flooding. The heavy rain and flood threat will become
more isolated this afternoon. An upper level trough will maintain a
moist airmass with plumes from the Pacific and Gulf of Mexico
continuing the high chances of showers and thunderstorms tonight into
Wednesday. Locally heavy rains are possible and may cause additional
or renewed isolated flooding. Wind gusts to 40 mph are also possible
with the stronger storms. Clouds and rain will keep temperatures
slightly below normal.

LONG TERM (Wednesday Night through Monday)...
Although some models try to rebuild the Subtropical Ridge back over
our area late week, expect a weakness in the height field or a shear
axis will likely occur. This maintains the plumes of moisture and
results in periods of showers and thunderstorms through next Monday.
The main threats are locally heavy rain possibly causing flooding
and gusty winds. Some models bring a surface boundary into our area.
This would enhance the rain and flood threat. Similar to the short
term, slightly below normal temperatures are expected.
