Areas affected...Texas Panhandle...Western Oklahoma

Concerning...Severe Thunderstorm Watch 330...

Valid 081204Z - 081400Z

The severe weather threat for Severe Thunderstorm Watch 330
continues.

SUMMARY...A wind-damage and isolated large hail threat will likely
continue for several more hours this morning across parts of the
Texas Panhandle and western Oklahoma. The severe threat could drift
southward into parts of West and Northwest Texas, where another
watch could be needed.

DISCUSSION...The latest high-resolution radar from Amarillo shows an
east-to-west line of strong to severe thunderstorms located from the
central Texas Panhandle eastward into western Oklahoma. The line is
along the northern edge of a pocket of moderate to strong
instability, where the RAP has MLCAPE in the 2500 to 3500 J/kg
range. This is reflected on the Amarillo 12Z sounding, which has
steep lapse rates in the 700 and 500 mb layer. Effective shear at
Amarillo is about 35 knots suggesting that the co*bination of CAPE
and shear is favorable for severe storms. In spite of a surface
inversion, the stronger cells within the line segment have produced
wind gusts above 65 knots, suggesting that the storms are rooted
closer to the surface. As the line moves southward into the stronger
instability, the severe threat should continue and weather watch
issuance will need to be considered.
