..DISCUSSION FROM RNOFWFVEF
 
 
NEAR NORMAL TEMPERATURES ARE EXPECTED THROUGH THE WEEKEND BEFORE A  
BRIEF COOL DOWN TO START OFF THE WORK WEEK. WIDESPREAD GUSTY WINDS  
WILL BEGIN SUNDAY AFTERNOON AND CONTINUE THROUGH MONDAY MORNING AS  
A RESULT OF AN UPPER-LEVEL DISTURBANCE MOVING INTO THE AREA. LESS  
WIND AND WARMING TEMPERATURES EXPECTED THROUGH THE LATTER PART OF  
THE WEEK.  
 
   
..DISCUSSION FROM LAXFWFSGX
 
 
AREAS OF SANTA ANA WINDS WILL CONTINUE IN THE FOOTHILLS AND  
PORTIONS OF THE VALLEYS THIS AFTERNOON. EXTEND PARTIALLY INTO  
VALLEYS TODAY, PEAKING LATE THIS MORNING. TOP GUSTS WILL BE 45-60  
MPH IN FAVORED POCKETS OF FOOTHILLS AND BELOW THE PASSES. THESE  
WINDS WILL BOOST THE FIRE POTENTIAL WITH RH VALUES DROPPING INTO  
THE SINGLE DIGITS THIS AFTERNOON. OVERNIGHT RELATIVE HUMIDITY  
RECOVERY WILL BE MODEST WITH ANOTHER ROUND OF (WEAKER) SANTA ANA  
WINDS LIKELY LATE TONIGHT INTO SATURDAY MORNING. THE SURFACE HIGH  
OVER THE GREAT BASIN WILL SHIFT EAST ON SATURDAY, AND A PACIFIC  
TROUGH WILL DEVELOP ALONG COASTAL CALIFORNIA THIS WEEKEND, ALLOWING  
THE MARINE LAYER TO BECOME BETTER ESTABLISHED ONCE AGAIN. WE EXPECT  
INCREASING AMOUNTS OF COASTAL LOW CLOUDS SATURDAY NIGHT THROUGH  
TUESDAY MORNING, WITH AREAS OF DRIZZLE POSSIBLE MONDAY MORNING.  
 
   
..DISCUSSION FROM PHXFWFPSR
 
 
DRY CONDITIONS WILL PREVAIL THROUGH SUNDAY WITH TEMPERATURES NEAR  
SEASONAL NORMALS, TOPPING OUT AROUND 90 DEGREES OVER THE LOWER  
DESERTS. BREEZY EAST TO NORTHEAST WINDS WILL BE POSSIBLE ACROSS  
SOUTH-CENTRAL ARIZONA SATURDAY MORNING AND EARLY AFTERNOON, WITH  
SOME RIDGETOPS EXPERIENCING GUSTS OVER 30 MPH. MIN RHS WILL  
GENERALLY RANGE FROM 10-15% FOR THE LOWER DESERTS TO 15-25% OVER  
THE EASTERN ARIZONA HIGH TERRAIN. OVERNIGHT RH RECOVERIES WILL  
RANGE FROM 25-40% FOR MOST LOWER DESERT LOCATIONS.
