URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 93

NWS Storm Prediction Center Norman OK

1250 PM CDT Tue Mar 28 2017



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  West and northwest Texas



* Effective this Tuesday afternoon and evening from 1250 PM until

  900 PM CDT.



* Primary threats include...

  Scattered large hail likely with isolated very large hail events

    to 2.5 inches in diameter possible

  A tornado or two possible



SUMMARY...Storms will continue to increase and steadily spread

north-northeastward across the Texas South Plains and Texas

Panhandle this afternoon. Large hail will be the primary risk,

especially northward into the Texas Panhandle where storms will be

increasingly elevated. An increasing surface-based severe risk later

this afternoon may result in an increasing tornado risk across parts

of the region including the Texas South Plains and Low Rolling

Plains, such that a new/replacement Tornado Watch would be needed

across these areas.



The severe thunderstorm watch area is approximately along and 70

statute miles east and west of a line from 55 miles north of Borger

TX to 55 miles south southeast of Lubbock TX. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU3).



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

few cumulonimbi with maximum tops to 500. Mean storm motion vector

20030.
