Area Forecast Discussion
National Weather Service Austin/San Antonio TX
232 PM CDT Thu Apr 9 2020

.SHORT TERM (Tonight through Friday Night)...
Strong to severe storms are firing along a Burnet to Boerne line
early this afternoon and are tracking ENE at 35 mph. With the front
only partially enhancing the storms near and north of Llano, it is
assumed that the explosive storm growth has not fully taken place.
Rapid refresh models have struggle the past couple days on getting
storm initiation points even remotely accurate. Nevertheless we have
active storms, and will a assume watches and warnings are imminent
in the next hour.

Satellite derived layer Pwat imagery seems to suggest this activity
more rooted in a shortwave lifting NE from W Texas toward N-Central
TX, and an 18Z special sounding confirms the front has already
passed the DRT area. So by 4 pm, the front could be more closely
aligned with the lead orientation of the storm clusters. What
appears less likely is that heavy rainfall potential may not need
inclusion for the Hill Country, and some last minute PoP adjustments
may be warranted for the first period.

By 6 pm, the front should have caught up with the leading edge of
storm, and should have moved through most of the Austin/San Antonio
metro areas. Unfortunately some of the best ingredients of high CAPE
and strong shear will be available to potentially bring some of the
stronger hail and high winds to some of our higher population
densities. The storms should accelerate slightly as the front and
storm complex become aligned, so we are not expected much more than
1 inch from some of the stronger storms. East of the metro area this
evening, we may see some of the hail reports decrease while the wind
reports increase.

By 9 pm, the front should have been through all counties with some
residual rain and storm activity lingering into midnight over
southern counties. A tranquil night should resume after midnight
with the north winds cooling us down into the mid 50s to mid 60s.

More and more, models are trending drier in the wake of the this
evening's activity, so PoPs for Friday are cropped way back from the
blended guidance. There remains a potential for strong storms near
the Rio Grande, but surface based deep convection and anything more
than some small hail is not expected. By late Friday afternoon, the
surface winds turn SE over all of South Central TX; thus Friday
night could see better coverage, but perhaps not much of a boost in
storm strength through 12Z Saturday.

&&

.LONG TERM (Saturday through Thursday)...
The wet weather pattern continues on Saturday as a warm front pushes
into our area from the Gulf waters. Dew point temperatures in the
60s and 70s ahead of a dry-line over the northeast part of Mexico
will set the stage for scattered showers and thunderstorms over most
areas. By Saturday afternoon, the dry-line is forecast to shift to
the east as well as the shower and thunderstorm activity. Some of
these storms could be strong to severe, capable of producing large
hail and damaging wind gusts. In addition, locally heavy rain is
possible.

We may see a break on Saturday afternoon into the early evening
hours across the Rio Grande and Edwards Plateau. However, a second
round of showers and thunderstorms is expected on late Saturday
evening. Some storms could be strong to severe, as an upper level
system over northern Mexico slowly moves to the east and over our
Saturday night into Sunday. Some lingering showers and storms could
affect the northeast part of the Hill Country and areas along
Interstate 35 corridor on Sunday morning, however, weather should
clear from west to east on mid-late Sunday morning. Expect plenty of
sunshine for Sunday afternoon with highs in the mid 70s to mid 80s.

A strong cold front will push across the area on Sunday night into
Monday with lows in the 40s across the Hill Country to the lower 50s
across the Rio Grande. The cooler airmass remains over the area on
Monday with highs in the 60s for most area. Dry weather conditions
persist through the week with a warming trend expected
for the latter part of the week.
