Area Forecast Discussion
National Weather Service Austin/San Antonio TX
1008 PM CDT Sun Jun 25 2017
.UPDATE...
Showers and thunderstorms have generally dissipated across the area
aside from some light stratiform rain over portions of Lee and
Fayette Counties that should dissipate over the next hour. Hi-res
models are generally in good agreement that additional convection
will not develop until possibly very late in the overnight hours
just before sunrise as some streamer showers and possibly a rogue
thunderstorm develops. Thus, we have removed rain chances over the
Rio Grande Plains for most of tonight and decreased to 20-30 POPs
elsewhere, only mentioning very isolated thunderstorms in the Coastal
Plains prior to 4 am. We have included 40 POPS for scattered shower
activity across most of the CWA from 4-10 am just in case remnant
outflow boundaries with nearly moist adiabatic lapse rates allow for
some early development, but only very isolated thunderstorms are
expected due to stability near the melting level.
Scattered showers and thunderstorms are expected across most of the
region by late tomorrow morning into the afternoon hours, with the
best chances for storm initiation in the Coastal Plains along outflow
boundaries and a possible sea breeze. Convection should also develop
over the Edwards Plateau and western Hill Country counties along an
outflow boundary expected to be near or northwest of our northwest-
most counties associated with a complex of storms expected to move
southeast tonight from the Texas panhandle. Depending on how far
southeast this activity makes it tonight, rain chances may need to be
increased later tomorrow afternoon and evening over much of the CWA
as additional shortwave forcing may help expand the coverage of
showers and thunderstorms along this particular outflow boundary.
