This Hazardous Weather Outlook is for the Texas and Oklahoma
Panhandles.

.DAY ONE...Today and Tonight.

Isolated to scattered severe storms are expected, mainly late
this afternoon and evening. Large hail, damaging winds and locally
heavy rainfall are the main threats from these storms, however an
isolated tornado can not be ruled out.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

There will likely be some threat for severe storms each afternoon
and overnight period through mid week. Heavy rainfall will also
accompany these storms and repeated days of thunderstorms
producing heavy rainfall will likely lead to an increasing threat
for flooding through mid week. Currently, it appears the greatest
potential for large hail, and damaging winds and tornadoes will
be on Sunday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed today and Sunday.
