Area Forecast Discussion
National Weather Service Austin/San Antonio TX
232 PM CDT Thu Jun 17 2021

.SHORT TERM (Tonight through Friday Night)...
Few to scattered afternoon cumulus clouds are in place across the
area at this time. There is a small chance for one or two showers to
develop within this cumulus field by sunset with the better chances
in the central CWA, but overall chances for measurable precipitation
was too low to mention in the forecast at this time. Temperatures
are currently in the lower to middle 90s across the area with
afternoon highs today expected to range from the lower 90s in the
Hill Country to near 100 towards the Rio Grande with middle 90s for
the remainder of the CWA. Quiet weather will continue tonight with
lows in the lower to middle 70s for most locations. Another dry day
is expected tomorrow with slightly cooler highs as the upper ridge
breaks down a bit further. Lows tomorrow night will also be slightly
cooler across the region. Otherwise, no major weather impacts are
expected during the short-term forecast.

&&

.LONG TERM (Saturday through Thursday)...
The low level flow will remain southeasterly to southerly over the
weekend. The upper level ridge over the southwestern US will suppress
vertical motion and dry weather will continue. Temperature will rise
a degree or two each day through Monday when most of the western half
of the CWA will be 100 or higher. Heat indices Monday will be 100 or
higher over the entire area and much of the area will be 110 or
above. A Heat Advisory will probably be needed. Models are in good
agreement that a late season cold front will move through the area
Monday night into Tuesday. This will bring cooler air and a chance
for showers and thunderstorms. Rain chances will begin Monday night
as the front passes through. High temperatures behind the front
Tuesday will be near 10 degrees cooler than Monday. The front will
stall near our southern border setting up a period will of low
chances for showers and thunderstorms through Wednesday. By Thursday
the front will have dissipated and dry weather will return.
Temperatures will creep back up Wednesday and Thursday.
