Severe Thunderstorm Watch Number 153
NWS Storm Prediction Center Norman OK
1250 PM MDT Sun Jun 3 2018
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Far west Texas
* Effective this Sunday afternoon and evening from 1250 PM until
900 PM MDT.
* Primary threats include...
Scattered large hail likely with isolated very large hail events
to 2 inches in diameter possible
Scattered damaging wind gusts to 70 mph possible
A tornado or two possible
SUMMARY...A northeastward-moving upper-level system will provide
ample shear and forcing for ascent, while relatively high moisture
content exists across the region. This scenario will support an
increasing coverage and intensity of storms this afternoon,
including some supercells. Large hail is likely to be the common
hazard, although severe-caliber winds may occur and even a tornado
or two cannot be ruled out given the relatively moist environment.
Storms may eventually form into a complex and spread eastward toward
west Texas this evening.
The severe thunderstorm watch area is approximately along and 100
statute miles east and west of a line from 55 miles north of Cuba NM
to 80 miles south of Guadalupe Pass TX. For a complete depiction of
the watch see the associated watch outline update (WOUS64 KWNS
