Area Forecast Discussion
National Weather Service Austin/San Antonio TX
248 PM CDT WED JUN 29 2016

.SHORT TERM (Tonight through Thursday Night)...
Expecting isolated showers and thunderstorms this afternoon and
early evening mainly across the coastal Plains and southwest
counties. These showers and storms are expected to form along an
outflow boundary that extends from Rocksprings to San Antonio to
Cuero pushing to the southwest. Some of these storms could
produce localized heavy rain as pwats range from 1.6 to 2.0
inches. Also, stronger storms could produce wind gusts of 30 to 40
mph based on v-shaped forecast soundings and DCAPE values over
1000 J/Kg. This activity should come to an end early this evening
with the loss of daytime heating. Dry and hot weather conditions
are in store for Thursday with isolated showers/storms confined to
the coastal Plains.



&&
.LONG TERM (Friday through Wednesday)...
Subtropical high will continue to build across the southwest
region and push to the east for the next several days. This will
keep South Central Texas dry with limited shower/storm activity
across the coastal Plains due to seabreeze interaction. As the
subtropical high pushes to the east and over the area over the
weekend into next week, a warming trend is expected with highs in
the mid to upper 90s over much of the area and near 100 to 102
degrees across the Rio Grande Plains. Heat indices will range from
the 102 to 110 degrees over the weekend into next week during the
afternoon hours especially along and east of Interstate 35. We
could be issuing several Heat Advisories for areas along and south
of Highway 90 and east of I-35 during the Fourth of July weekend
holiday and beyond.
