Area Forecast Discussion
National Weather Service Austin/San Antonio TX
705 AM CDT Sat Sep 8 2018

.UPDATE...
Please see the 12Z aviation forecast discussion below.

&&

.AVIATION...
Convection has temporarily weakened along the I-35 corridor this
morning and we will only mention VCSH along with MVFR cigs. Out west
at DRT, convection is more widespread and have opted to go with
prevailing -SHRA and TEMPO groups for TSRA this morning. There will
be a very good chance for continued shower and thunderstorm
development this afternoon and evening with daytime heating and a
slow moving cold front.

&&

.PREV DISCUSSION... /ISSUED 450 AM CDT Sat Sep 8 2018/

..Locally Heavy Rain and Flash Flooding Possible...

SHORT TERM (Today through Sunday)...
Widespread rain is expected today through Sunday especially along
and west of Interstate 35. A Flash Flood Watch is now in effect for
areas along and west of I-35 through Sunday morning.

Rich tropical moisture coupled with a slow moving frontal boundary
will lead to localized heavy rain today through Sunday. Scattered to
numerous showers and thunderstorms are expected ahead of the actual
frontal boundary for most of the today period. Later this afternoon
and evening, the frontal boundary is forecast to push across the Rio
Grande Plains. An upper level disturbance across the Southern Plains
will also serve to enhance shower and thunderstorm development late
tonight into Sunday.

Storm total amounts of 1 to 3 inches are possible with isolated
amounts up to 7 inches. The heavy rains should become more
isolated Sunday afternoon, allowing the flash flood concerns to
decrease.

LONG TERM (Sunday Night through Friday)...
The upper level disturbance moves to the southeast Sunday evening
while an upper level ridge builds into our area from the west. This
will allow for showers and thunderstorms to decrease or come to an
end from the northwest to southeast parts of South Central Texas.

Some HiRes and medium-range models suggest for the frontal boundary
to stall across the Coastal Plains Sunday evening into Monday for
chances of rain over that area. Several upper level short-waves are
expected to move across South Central Texas for the first part of
next week to keep rain chances over parts of the southeast and
Coastal Plains.

An inverted upper level trough is forecast to move across the
southern coastal states into our area later in the week for rain
chance mainly across the eastern half of South Central Texas.

Temperatures will be cooler and slightly below climate normal values
through the period due to cloud coverage and wet soils.
