.SHORT TERM...
(Tonight through Sunday night)
Issued at 244 PM CDT Sat May 24 2025

Key Messages:

- Moderate to Extreme Risk of Heat-Related Impacts (level 2/4 out
  of 4)

High pressure is expected to continue to dominate the forecast
through Sunday afternoon. The increased subsidence will lead to
warmer temperatures and slightly lower moisture (PWAT values near
1.5"). Although moisture will be slightly lower, enough will linger
to yield a Moderate to Extreme risk of heat-related impacts
throughout the day Sunday. The Moderate risk can be expected across
the Coastal Bend with an area of Extreme risk across La Salle and
McMullen counties. Elsewhere, a Major risk of heat-related impacts
is expected. By Sunday night, an upper level disturbance will begin
to sweep across the Southern Plains ejecting an area of positive
vorticity advection into South Texas promoting a very low chance
(less than 15%) of showers across the northwestern Brush Country.
Similarly to last night, there is also a low chance for patchy fog
across the Coastal Plains late tonight into tomorrow morning.

Please use caution if outdoors and remember to remain hydrated and
take frequent breaks. More heat safety information can be found at
weather.gov/heat

.LONG TERM...
(Monday through next Friday)
Issued at 244 PM CDT Sat May 24 2025

Key Messages:

- Moderate to Extreme risk of heat related impacts across South
  Texas through Memorial Day.

- Low to medium chance of showers and thunderstorms all next week.

We`ll have ridging to our east to start out the long term period as
the pattern transitions due to an approaching trough connected to a
mid-level low moving out across the northern Plains. Several
shortwaves will round the southern periphery of this trough across
Texas with PVA mainly over north/central TX. Combined with an
approaching cold front attempting to push through our CWA mid-week,
will result in low to at times medium rain/storm chances (20-40%)
peaking around 50% Tuesday into Wednesday over northwestern Webb
county.

The heat risk across much of the region will be Major to Extreme on
Memorial Day with maximum heat indices generally up to 110-115.
Tuesday has a Moderate to Major heat risk with maximum heat indices
mainly 105-110 and a Minor to Moderate heat risk for the remainder
of the period.

Daily afternoon surface temperatures will generally range 90-105
degrees across the region through Tuesday with 90 to around 100
degrees the rest of the work week. Overnight lows across the region
will start off in the mid to upper 70s Monday night then low to mid
70s are forecast through the end of the period.

If planning outdoor activities early next week, closely monitor
the weather conditions and prepare to adjust plans to accommodate
frequent breaks to avoid heat-related illnesses. Always, practice
heat safety: drink plenty of water, wear lightweight, loose-
fitting and light-colored clothing, and apply sunscreen. Never
leave anyone in a vehicle unattended and don`t forget to check the
backseat!
