HOT AND DRY WEATHER WILL CONTINUE TO BUILD IN.

DRIVEN AFTERNOON GUSTS. LOCALIZED INVERSIONS WEAKEN AND LIFT IN
THE AFTERNOONS. RECOVERIES WILL BE IN THE LOW TO UPPER 40S
MONDAY. A CUTOFF LOW OFF THE COAST WILL DRIVE IN SOME ELEVATED
MOISTURE AND INSTABILITY ON MONDAY. THIS WILL BRING A 10 TO UP TO
15% CHANCE FOR THUNDERSTORMS OVER SOME PORTIONS OF THIS ZONE
MONDAY AFTERNOON, WITH BETTER CHANCES FARTHER NORTH. CONFIDENCE IS
LOW FOR THUNDERSTORM DEVELOPMENT HERE, BUT IN THE LEAST, THE INCREASING
INSTABILITY WILL IMPROVE VENTILATION.
