Area Forecast Discussion
National Weather Service Austin/San Antonio TX
251 PM CDT TUE AUG 16 2016

.SHORT TERM (Tonight through Wednesday Night)...
A very active weather period continues for August across South-
Central Texas this afternoon. Numerous showers and thunderstorms
are in place across the eastern two-thirds of the region. With
more thunderstorms around today versus the past several days we
are seeing 1-2 inches of rain fall in one hour rainfall which is
leading to minor flooding of creeks, streams, and low-lying
areas. Overall, the current trend of activity should persist
through the late afternoon and evening hours. Should see activity
diminish in coverage after 9 pm or so, similar to previous nights
with convection likely firing once again after midnight. The
stalled frontal boundary should be pushed north of the region by
tomorrow which means we will likely lose some of our focus for
shower and storm development. Precipitable water values will
remain above 2 inches across most of the CWA with warm air
advection at 850 mb feeding into a trough just north of the area.
This will likely continue the chances for a decent coverage of
showers and thunderstorms with the bulk of the activity possibly
across the northern Hill Country in closer proximity to the 850 mb
trough axis. The soils across the area have become very saturated
and any rainfall tomorrow will likely continue to pose a minor
flash flooding threat. Also, with slightly warmer temperatures
tomorrow, the chances for deep convection is higher which could
lead to higher rainfall rates from more efficient storms. Have
opted to extend the Flash Flood Watch through 7 PM Wednesday to
cover the additional threat of flash flooding.

Tomorrow night should be similar to tonight with a decreasing
coverage of shower and storm activity. Temperatures in the short-
term will continue to be influenced by the abundant cloud cover
and rainfall with highs in the lower 80s to near 90 and lows in
the lower to middle 70s.

&&

.LONG TERM (Thursday through Tuesday)...
For Thursday, the shear axis will still be in place across Texas
with precipitable water values greater than 2 inches for most of
the region. Will continue chance PoPs for most of the area with
the higher PoPs across the eastern CWA where the best moisture
will be located. Moisture values will drop off on Friday which
should decrease the coverage of showers and thunderstorms and will
only show 20-30 PoPs for the area.

The forecast for the weekend and into Monday shifts with some
uncertainty regarding the next Central Plains trough and another
possible weak or stalling frontal boundary moving into South-
Central Texas. A fairly deep trough for August is expected to pass
through the plains by Sunday morning and will send a front into
Texas on Sunday. The GFS and the ECMWF have some discrepancies
regarding how far south this front will go. The ECMWF is more
bullish and brings the boundary into the CWA which would likely
equate to a higher coverage of shower and storms Sunday and into
Monday. On the other hand, the GFS keeps the front to the north
and has a lower coverage of activity. Given the strength of the
trough and the history with the current system, want to lean more
to the ECMWF. Any frontal boundary should be gone by Tuesday and
will decrease the coverage of activity.
