(Today and tonight)
Issued at 354 AM CDT Fri May 24 2024

A weak cold front will drop south across the Big Country by this
afternoon, with the dryline advancing into far eastern portions of
the forecast area by late afternoon. CAMs continue to be anemic
regarding convective development this afternoon. Despite the lack
of any appreciable upper level support, isolated strong/severe
storms are possible south of the front and east of the dryline
during peak heating (San Saba and Mason counties). Any storms that
develop will have the potential to produce large hail. Otherwise,
the front should reach portions of the Concho Valley and
Heartland by early evening before lifting back north tonight.
Highs today will range from the upper 80s and lower 90s across
the Big Country, to the upper 90s/low 100s over southern counties.
Lows tonight will be mainly in the 60s.

.LONG TERM...
(Saturday through Thursday)
Issued at 455 AM CDT Fri May 24 2024

Hot temperatures will prevail this Memorial Day holiday weekend. The
dryline will mix east across approximately the western half of our
area Saturday, and through our entire area on Sunday. Given the
strength of the 850mb thermal ridging pattern and with ample
sunshine, highs are expected to be mostly in the upper 90s to 105
degrees across our area. Ahead of the dryline Saturday afternoon,
higher heat index values can be expected across the Heartland,
Northwest Hill Country and eastern Big Country. While the
possibility of a thunderstorm or two cannot be completely ruled
out Saturday afternoon ahead of the dryline in our eastern
counties, low confidence precludes a mentionable PoP except for
the far eastern Big Country. If a storm can develop, large to very
large hail and damaging winds would be possible given the
forecast strong instability with 35-45 knots effective bulk shear.

On Memorial day, a cold front is progged to move south across the
Big Country and possibly into our central counties by late
afternoon, and then across the southern half of our area Monday
night. Temperatures Monday will be a little cooler across the
northern third of our area with highs in the lower to mid 90s.
Highs ahead of the front south will reach the upper 90s to near
105 once again. If an embedded disturbance aloft moves over the
area, could have a possibility of showers and thunderstorms. At
this time, think any rain chances will be to our east/southeast
Monday.

Temperatures should be at least a little cooler Tuesday into
Thursday of next week, with increased cloud cover and chances for
showers and thunderstorms. With increased moisture during that
time, could have a couple of shortwave troughs move across our
area. Preliminary indication is for highs to range from the mid
80s to mid 90s in our area.

(06Z TAFS)
Issued at 1247 AM CDT Fri May 24 2024

Stratus is expected to develop across the southern terminals
towards daybreak and linger through the mid/late morning hours
before scattering out to VFR. Haze will also be possible across
the area through the morning hours, reducing visibilities to
around 5SM at times. A weak cold front will move south across the
KABI terminal by 18Z, shifting winds to a northerly direction for
the afternoon hours. The front may make it as far south as KSJT
by mid afternoon before lifting farther north tonight. Any
thunderstorm development this afternoon and evening should
remain east of the terminals.
