.SHORT TERM...
(Tonight through Tuesday night)
Issued at 213 PM CDT Mon Jun 24 2024

The upper level ridge centered over and northwest of the area will
continue to produce for most locations a dry forecast through the
short term. Beneath the ridge is a pool of elevated moisture across
the Coastal Plains and there is a 10-20% chance of stray to isolated
tropical showers and thunderstorms in forecast this afternoon across
this area. A few CAMs bring stray showers near the San Antonio metro
area early in the evening. Activity should dissipate after sunset.
Again, most locations will stay dry.

Otherwise warm and humid conditions. This afternoon, some isolated
spots in the Coastal Plains and near the I-35 corridor could see
peak heat index values of around 105-108 degrees. We will issue a
Special Weather Statement for this. Heat index values and the heat
risk increase slightly Tuesday afternoon.

.LONG TERM...
(Wednesday through Monday)
Issued at 213 PM CDT Mon Jun 24 2024

The subtropical ridge will keep dry weather in place at the start of
the long term. High temperatures will continue to be mostly in the
90s across the CWA Wednesday and Thursday. Afternoon dewpoints in the
70s may push heat indices (HI) to advisory levels over the Coastal
Plains and I-35 Corridor Wednesday. However, slightly better mixing
Thursday may keep HI below criteria. A trough at 500 mb will push
the upper ridge to the west Thursday and this weakness on the eastern
side may allow isolated convection over the Coastal Plains Friday
and Saturday afternoons. Temperatures will be about the same for the
end of the work week and weekend. Another uptick in dewpoint
temperatures Saturday may push HI to advisory levels, but they drop
back down again for Sunday and Monday.

.AVIATION...
(06Z TAFS)
Issued at 1215 AM CDT Tue Jun 25 2024

Patchy stratus is beginning to form north of a UVA-HDO-SAT line. The
stratus will expand in coverage across the Hill Country and I-35
corridor through the overnight, and potentially into the Rio Grande
briefly 12Z-14Z. Mainly MVFR ceilings are expected with this stratus,
however some patchy IFR ceilings are possible across the Hill
Country. The stratus is expected to gradually scatter out 15Z-17Z
with VFR conditions thereafter.
