Severe Thunderstorm Watch Number 77
NWS Storm Prediction Center Norman OK
635 PM CDT Sun Mar 30 2025
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Northwest Louisiana
Southeast and East-Central Texas
* Effective this Sunday night and Monday morning from 635 PM
until 200 AM CDT.
* Primary threats include...
Scattered large hail and isolated very large hail events to 2.5
inches in diameter likely
Scattered damaging wind gusts to 70 mph likely
A tornado or two possible
SUMMARY...Thunderstorms coverage is expected to increase over the
next few hours across southeast and east-central TX before then
continuing downstream into northwest LA. Strong instability and
moderate shear will support the potential for supercells. The
primary severe hazard with these supercells will be large to very
large hail (i.e. greater than 2" in diameter). Strong wind gusts
could occur as well. Given the potential for a supercell mode, a
tornado or two is also possible.
The severe thunderstorm watch area is approximately along and 40
statute miles north and south of a line from 35 miles north
northwest of College Station TX to 35 miles southeast of Shreveport
LA. For a co*plete depiction of the watch see the associated watch
outline update (WOUS64 KWNS WOU7).
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.
