A RED FLAG WARNING IS IN EFFECT FOR THE SAN BERNARDINO AND
RIVERSIDE COUNTY MOUNTAINS AND THE HIGH DESERT UNTIL SUNDAY
EVENING. CHANCES OF THUNDERSTORMS WITH THE POTENTIAL FOR DRY
LIGHTNING THIS WEEKEND IN THE MOUNTAINS AND LOCALLY INTO THE
DESERTS. WHERE CELLS DEVELOP, SOME WETTING RAIN IS EXPECTED BUT
LIGHTNING HAS THE POTENTIAL TO STRIKE UP TO 15 MILES AWAY FROM A
THUNDERSTORM. IF LIGHTNING STRIKES AWAY FROM WETTING RAIN, FIRE
STARTS ARE POSSIBLE DUE TO VERY DRY FUEL CONDITIONS. STRONG AND
ERRATIC WINDS ARE EXPECTED NEAR WHERE THUNDERSTORMS DEVELOP. GUSTS
35 TO 50 MPH ARE POSSIBLE. STRONG AND ERRATIC WIND GUSTS NEAR
THUNDERSTORMS HAVE THE POTENTIAL TO CAUSE RAPID SPREAD OF ONGOING
OR NEW FIRES. THE HIGHEST CHANCES OF THUNDERSTORMS IS TODAY, WITH
LESSER CHANCES SUNDAY. BY MONDAY, CHANCES WILL BE QUITE ISOLATED
AND CONFINED TO THE MOUNTAINS AS THE ATMOSPHERE SLOWLY DRIES OUT.
IN ADDITION TO THE THUNDERSTORM POTENTIAL, THERE WILL BE A GRADUAL
AND SLOW COOLING WITH INCREASED HUMIDITY INTO SUNDAY.
TEMPERATURES WILL GRADUALLY BEGIN TO INCREASE BY THE MIDDLE OF
NEXT WEEK WITH DECREASING HUMIDITY IN THE MOUNTAINS AND DESERTS.

...DISCUSSION FROM PHXFWFPSR...


SHOWERS AND ISOLATED THUNDERSTORMS EARLY THIS MORNING ACROSS SOUTH-
CENTRAL ARIZONA WILL GIVE WAY TO QUIETER CONDITIONS GOING THROUGH
THE REST OF THE DAY TODAY. THUNDERSTORM ACTIVITY WILL PRIMARILY
REMAIN CONFINED TO THE NORTHERN ARIZONA HIGH TERRAIN THIS AFTERNOON
AND EVENING. THUNDERSTORM CHANCES WILL BE HIGHEST SUNDAY, WITH
BETTER POTENTIAL FOR ACTIVITY TO DESCEND INTO THE LOWER DESERTS OF
SOUTH-CENTRAL ARIZONA. ANY THUNDERSTORM WILL BE CAPABLE OF PRODUCING
 STRONG ERRATIC OUTFLOW WINDS, WHICH COULD TRAVEL A LONG WAYS OUT
FROM THE STORMS, FREQUENT LIGHTNING, AND BRIEF HEAVY RAINFALL.

ASIDE FROM THUNDERSTORMS, WINDS WILL BE FAIRLY LIGHT AND FOLLOW
TYPICAL DIURNAL WIND TENDENCIES, WITH AFTERNOON GUSTS UP TO 15-25
MPH. MOISTURE LEVELS WILL BE ON THE RISE THROUGH THIS WEEKEND,
PUSHING MINRH VALUES UP FROM 15-25% TODAY TO UPWARDS OF 20-30% ON
SUNDAY. TEMPERATURES THIS WEEKEND WILL GRADUALLY DECREASE BUT WILL
CONTINUE TO REMAIN ABOVE NORMAL.

...THUNDERSTORMS IMPLY GUSTY WINDS...

NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND IN
THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
