Severe Thunderstorm Watch Number 40
NWS Storm Prediction Center Norman OK
150 AM CDT Sun Apr 7 2019
The NWS Storm Prediction Center has issued a

South central Texas
Coastal Waters

* Primary threats include...

A tornado or two possible
SUMMARY...A cluster of thunderstorms over northeast Mexico will move
across the Rio Grande into south Texas through the early morning
hours, and the storms will become more organized with time. The
storm environment will initially favor large hail as the main threat
with embedded supercells, but damaging winds will become more of a
threat as the storms grow into a bowing line. An isolated tornado
or two cannot be ruled out with embedded supercell or mesovortex
circulations.
The severe thunderstorm watch area is approximately along and 70
statute miles north and south of a line from 30 miles west of Laredo
TX to 30 miles south of Victoria TX. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU0).
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.
&&
AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 550. Mean storm motion vector
27025.
