NWS Storm Prediction Center Norman OK
440 PM CDT Thu May 1 2025
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
South-Central and South Texas
* Effective this Thursday afternoon from 440 PM until Midnight
CDT.
* Primary threats include...
Scattered damaging winds and isolated significant gusts to 75
mph possible
Scattered large hail and isolated very large hail events to 3.5
inches in diameter possible
SUMMARY...Isolated to widely scattered thunderstorms are forecast to
develop through the late afternoon and into the evening. A very
unstable airmass and adequate deep-layer shear will promote
supercell development. Large to giant hail is possible with the
stronger storms. By this evening, a few storms may congeal and move
east of the Rio Grande into parts of south Texas, posing a risk for
large hail and severe gusts.
The severe thunderstorm watch area is approximately along and 80
statute miles east and west of a line from 15 miles northwest of
Junction TX to 50 miles west southwest of Laredo TX. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU5).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.
