...DISCUSSION FROM RNOFWFVEF...



THIS AFTERNOON, RHS WILL DROP TO AROUND 15 TO 30   PERCENT AREAWIDE,

WITH ISOLATED SHOWERS FROM THE SOUTHERN GREAT BASIN TO THE 

NORTHERN MOJAVE DESERT. WETTING RAINS ARE NOT EXPECTED, AND A 

LIGHTNING STRIKE OR TWO CANNOT BE RULED OUT, ESPECIALLY ACROSS 

PORTIONS OF THE SOUTHERN GREAT BASIN THROUGH EARLY EVENING. 

TONIGHT, SHOWERS DIMINISH WITH 20FT WINDS BECOMING LIGHT AND 

GENERALLY GOOD NOCTURNAL RECOVERY AS RHS REBOUND TO 30 TO 60 

PERCENT. THE WARMING AND DRYING TREND CONTINUES TUESDAY ONWARD, 

WITH RHS BOTTOMING OUT AROUND 10 TO 20 PERCENT AND DRY CONDITIONS 

EXPECTED. ABOVE NORMAL TEMPERATURES RETURN WEDNESDAY THROUGH 

FRIDAY.





...DISCUSSION FROM LAXFWFSGX...





DRY WITH MINOR WARMING THROUGH MOST OF THIS WEEK, WITH HIGH 

TEMPERATURES NEAR TO SLIGHTLY ABOVE NORMAL AND TYPICAL DIURNAL 

WINDS. ANOTHER LOW PRESSURE SYSTEM WILL BRING STRONG WESTERLY WINDS

FOR NEXT SATURDAY AND SUNDAY ALONG WITH CHANCES FOR SHOWERS SATURDAY

NIGHT AND SUNDAY.





...DISCUSSION FROM PHXFWFPSR...





BELOW NORMAL TEMPERATURES TODAY WILL RESULT IN MINIMUM RH VALUES 

ABOVE 15%, HOWEVER WARMING CONDITIONS THE REST OF THE WEEK, BACK TO 

SLIGHTLY ABOVE NORMAL BY WEDNESDAY, WILL DROP MINIMUM RH VALUES BACK

 DOWN TO AROUND 10-15% EACH AFTERNOON THROUGH AT LEAST FRIDAY. A

COOL  WEATHER SYSTEM WILL THEN APPROACH AND MOVE THROUGH THE REGION

THIS  WEEKEND. THIS WILL BRING MINIMUM RH VALUES BACK ABOVE CRITICAL

 LEVELS. HOWEVER, THIS SYSTEM WILL ALSO BRING INCREASED GRADIENT 

WINDS ACROSS THE AREA AND IT LOOKS AS THOUGH THERE WILL BE A PERIOD 

OF AT LEAST ELEVATED FIRE WEATHER CONDITIONS FOR SOUTH-CENTRAL AZ 

SATURDAY AFTERNOON. WINDS WILL MAINTAIN SEASONALLY TYPICAL UPSLOPE 

GUSTINESS IN THE AFTERNOON THROUGH THE ENTIRE WEEK WITH LIKELY 

STRONGER GUSTS ARRIVING THIS WEEKEND. PREDICTIVE SERVICES STILL SHOW

 ERCS ARE BELOW THE 75TH PERCENTILE, WHICH SHOULD HELP LIMIT THE 

LARGE FIRE RISK.
