EACH AFTERNOON WILL REMAIN IN PLACE ACROSS THE REGION THE REST OF  
THE WEEK. TEMPERATURES WILL PULL BACK TO NEAR NORMAL TUESDAY THEN

DISCUSSION
 
THE EXCESSIVELY HIGH TEMPERATURES WHICH HAVE BEEN IN  
PLACE OVER THE REGION SINCE SATURDAY WILL PULL BACK NEAR NORMAL  
AFTER TODAY. HIGHS THIS AFTERNOON WERE RUNNING 2-3 DEGREES LOWER  
THEN SUNDAY AND WILL DECREASE AN ADDITIONAL FEW DEGREES TUESDAY THEN  
HOLD FAIRLY CONSISTENT THROUGH THE WEEKEND AND EARLY NEXT WEEK. THE  
SOUTH-SOUTHWEST WINDS GUSTING 30-35 MPH THIS AFTERNOON WILL  
GRADUALLY DECREASE THIS EVENING BUT SPEEDS OF 15-20 MPH WILL BE  
FAIRLY COMMON OVERNIGHT FOLLOWED BY GUSTS 25-30 MPH LATE TUESDAY  
MORNING THROUGH THE AFTERNOON. AFTERNOON BREEZES WITH GUSTS 20-25  
MPH CAN BE EXPECTED EACH DAY GOING INTO THE WEEKEND.  
 
THE FORECAST WILL REMAIN DRY FOR THE MAJORITY OF THE REGION THROUGH  
THE WEEKEND, BUT MODEL ENSEMBLES ARE BEGINNING TO INDICATE SOME  
POTENTIAL FOR MOISTURE WITH PRECIPITABLE WATER VALUES OVER ONE INCH  
TO HEAD OUR WAY AS DEEPER SOUTHEAST FLOW DEVELOPS ACROSS NORTHWEST  
ARIZONA AND SOUTHERN NEVADA/CALIFORNIA IN RESPONSE TO AN INVERTED  
TROUGH MOVING ACROSS CENTRAL SONORA/BAJA AND HIGH PRESSURE BECOMING  
CENTERED CLOSER TO THE FOUR CORNERS. NOT A LOT OF CONFIDENCE YET,  
BUT IT IS AT LEAST SOMETHING TO WATCH FOR A CHANGE IN THE WEATHER.

NORTHWEST ARIZONA WILL END THIS EVENING AS GUSTY SOUTHWEST WINDS
