Severe Thunderstorm Watch Number 76

NWS Storm Prediction Center Norman OK

1205 PM CDT Fri Apr 9 2021



The NWS Storm Prediction Center has issued a

SUMMARY...Thunderstorms now forming across northeastern Texas are

expected to intensify this afternoon while spreading eastward across

northwestern Louisiana and southern Arkansas.  Isolated very large

hail will be possible with any more discrete supercells, while

damaging winds will become more of a threat as storms grow upscale

into clusters and line segments.  An isolated tornado cannot be

ruled out with storms interacting with a surface front/outflow

boundary across the watch area.



The severe thunderstorm watch area is approximately along and 60

statute miles north and south of a line from 30 miles north

northwest of Longview TX to 35 miles east northeast of Monticello

AR. For a complete depiction of the watch see the associated watch

outline update (WOUS64 KWNS WOU6).



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

2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
