Area Forecast Discussion
National Weather Service Austin/San Antonio TX
631 PM CDT Fri May 31 2024

...New AVIATION...

.SHORT TERM...
(Tonight through Saturday night)
Issued at 202 PM CDT Fri May 31 2024

Unfortunately, there continues to be low confidence in the forecast
through the short term regarding the timing and location of any
additional showers and thunderstorms. CAMs continue to depict
isolated to scattered convection developing this afternoon/evening,
though there are large differences in where and when. Therefore,
we'll be focusing our attention on some of the most likely areas for
development which include a surface boundary approaching the
northern Hill Country which is evident in airport observations and
satellite imagery, a dryline that remains in west Texas, and the SDB
Mountains in Mexico. Convection is already noted over the mountains,
though any convection that develops along the aforementioned
boundary will likely impact the area first due to its proximity.
Regardless of where and when storms develop, there remains a threat
for a few severe thunderstorms as there is plenty of SBCAPE west and
sufficient elevated instability remaining where storms moved through
this morning. There remains plenty of effective bulk shear as well.
Large hail will be the main threat with storms today with a
secondary threat for damaging wind gusts.

Any activity should diminish after sunset with generally quiet
conditions overnight. Additional isolated strong to severe
thunderstorm activity is possible tomorrow afternoon, with a focus
on the coastal plains during the afternoon associated with a weak
500mb disturbance, transitioning to western areas in the evening as
dryline activity will attempt to push into the area.

&&

.LONG TERM...
(Sunday through Friday)
Issued at 202 PM CDT Fri May 31 2024

Much of the upcoming week is largely expected to remain precipitation
free along with above normal temperatures across all areas. Expect
daytime highs to range from the lower 90s to near 103 degrees Sunday
through Tuesday, with highs increasing into the mid 90s to 110
degrees for the remainder of the forecast period. Overnight lows will
be warm as well, with 70s to near 80 for most locations. The NBM
numbers looked too low and we have bumped these values up for the mid
to late week period. With temperatures set to increase and recent
rains helping to keep humidity levels up, we will likely see the
return of heat headlines for a good portion of the upcoming work
week.

We will keep a low chance for afternoon showers and storms in
the forecast for Sunday across our far northern counties. The models
indicate some weak lift embedded in the west/southwest flow aloft
will move across the region. As we head into the middle to late
portion of the forecast, the medium range models show the subtropical
ridge building to our west, which would bring some northwest flow
aloft to the region. These types of patterns to tend to favor late
night/early morning MCS activity, but overall confidence in the
details is low at this time.

&&

.AVIATION...
(00Z TAFS)
Issued at 631 PM CDT Fri May 31 2024

VFR conditions will continue through 08-10Z before MVFR ceilings
redevelop across much of South Central Texas. Low stratus should
scatter and lift between 16-18Z tomorrow when VFR conditions return.
Expect any shower or thunderstorm activity to remain in the Hill
Country this evening and have kept dry conditions at all sites.
Additional isolated thunderstorms are possible Saturday, but low
confidence in placement and timing.
