This Hazardous Weather Outlook is for portions of northwest Texas
and the Panhandle of Texas.

.DAY ONE...This Afternoon and Tonight

Isolated to scattered thunderstorms developing in the vicinity of
surface low pressure will spread eastward from areas to the south
of Lubbock toward the Rolling Plains. These thunderstorms will
initially have the potential for wind gusts to 65 mph, and will
add the potential for hail to the size of golfballs as they move
into better low level moisture across and adjacent to the southern
Rolling Plains. The greatest risk of severe weather will be south
of a Lubbock to Paducah line.

Gusty north to northeast winds will develop behind a cold front
tonight. The strongest winds are expected near the New Mexico
state line from Friona and Bovina southward to Plains and Denver
City. A Wind Advisory has been issued for this area from 8 PM to 5
AM.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Thunderstorm chances, and the risk of severe weather, may increase
Sunday into Monday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be requested this afternoon and evening.
