.KEY MESSAGES...
Updated at 522 PM CST Sat Mar 7 2026

- Medium to high rain chances (50-90%) this weekend. A Marginal
Risk (level 1 of 4) of Excessive Rainfall is in place for most of
South Texas today.

- A Slight Risk (level 2 of 5) for severe weather is in place for
  today over the northern to northeastern portions of the area,
  with a Marginal Risk (level 1 of 2) for the remainder of South
  Texas. The main hazards will be large hail to very large hail
  possible and damaging winds.

&&

.DISCUSSION...
Issued at 234 PM CST Sat Mar 7 2026

Per satellite imagery cloud appear to be breaking to allow for
daytime heating ahead of the impending cold front. The 18Z sounding
has about 2600 J/kg sbcape over the region with no CIN. Surface to
equilibrium level bulk shear (71 knots), steep 700 to 500mb lapse
rates (7.6 degrees C/KM), and moderate to high MUCAPE (2627 J/Kg)
are all pointing to large to very large hail being a definite
threat. The environment does also support a damaging wind threat
with the potential for microbursts. The likely timing of storms
entering the area will be around 4-6 PM. Showers and storms are
expected to persist through the overnight period into tomorrow
morning. Due to these factors SPC maintained our region northern to
northwestern portions of the region in a Slight Risk (2 out of 5),
with the remainder of South Texas in a Marginal Risk(1 out of 5).

Model guidance has trended back on rainfall total amounts
tremendously. This time yesterday, models were forecasting amounts
in the Brush Country mainly around 2-3 inches with locally higher
amounts. This cycle we are now only expecting amounts up to an inch
with locally higher amounts. This is due to model guidance favoring
towards a faster solution for showers and storms to move through the
region. This is likely due to forecasted stronger bulk shear values
around 50-60 knots. Other factors such as DCP of 2 (derecho
composite parameter), Effective bulk shear difference (28 knots),
high MUCAPE (2627 J/Kg), and efficient 0-6km mean wind (19 knots)
supports storms congealing into a line of convection with likely
embedded supercells. This would limit the potential for flooding
rain though it will remain possible. Due to this WPC has
transitioned all of South Texas into a Marginal Risk (1 out of 5)
for Excessive Rainfall. Activity should begin to wind down by Sunday
morning, with rain chances waning throughout the remainder of the
day for majority of the region. Low chances for rain will exist for
the beginning of the week. By midweek we will see another
disturbance swing through the region bringing our next best chance
for rain.

.AVIATION...
(00Z TAFS)
Issued at 522 PM CST Sat Mar 7 2026

Showers and thunderstorms have developed to the north of COT and
VCT. Expect convection will start to develop over South Texas in
the next hour or two and continue through the night. Some storms
could be strong to severe, particularly over the Brush Country.
Large hail, damaging winds, and high rainfall rates are possible.
By late tonight/early Sunday morning, convection will likely have
decreased, with some lingering showers expected into the
afternoon. Low to medium rain chances will continue through Sunday
area wide.

VFR visibility will linger with VFR ceilings becoming MVFR to IFR
between 02Z and 06Z, with IFR to LIFR ceilings and visibility
possible in and around any thunderstorms. Winds will shift from
southeast to the north/northeast.

&&

.MARINE...
Issued at 234 PM CST Sat Mar 7 2026

Moderate (BF 4) southeasterly flow is expected today. Winds will
diminish to a gentle to moderate (BF 3-4) tonight through Monday.
Winds will increase once again to a moderate to fresh breeze (BF
4-5) Monday night ahead of another cold front. A medium to high
(40-70%) chance of showers and thunderstorms will develop this
afternoon and tonight and continue through Sunday before
decreasing to a low (<25%) chance Sunday night that will persist
into early next week.

&&

.FIRE WEATHER...
Issued at 234 PM CST Sat Mar 7 2026

Rain chances will increase to medium to high (50-90%) today as a
cold front moves into the area. Strong to severe thunderstorms are
possible, especially over the Brush Country. With expected rainfall,
increased moisture, and a decrease in the winds, elevated fire
weather conditions are not anticipated.
