NORTH EITHER ACROSS THE EXTREME EASTERN PERMIAN BASIN OR EXTREME
WESTERN LOW ROLLING PLAINS PER CUMULUS FIELD DEVELOPING AND VERY DRY
AIR BEHIND THE DRYLINE PUSHING EAST. ANY THUNDERSTORM THAT FORMS
COULD BECOME SEVERE BUT WILL NOT MENTION IN ZONES WITH ISOLATED
NATURE OF ACTIVITY EXPECTED. BROUGHT LOW CLOUDS IN AGAIN IN THE EAST

BORDER. INCREASED THE WIND SPEEDS GRIDS THIS EVENING BUT LITTLE
CHANGE TO THE OTHER GRIDS.
