ARIZONA AND SOUTHEAST CALIFORNIA
NATIONAL WEATHER SERVICE PHOENIX AZ
201 PM MST FRI JUL 3 2026
DISCUSSION
BUILDING HIGH PRESSURE THROUGH THIS WEEKEND WILL LEAD TO GRADUALLY
WARMING, BUT NEAR NORMAL, TEMPERATURES. WINDS WILL REMAIN FAIRLY
LIGHT THIS WEEKEND WITH ONLY THE TYPICAL AFTERNOON
UPSLOPE/UPVALLEY 15-20 MPH GUSTS AND MAINLY ON SUNDAY DUE TO
BETTER MIXING WITH LESS CLOUD COVER THAN SATURDAY. AFTERNOON
MINIMUM HUMIDITIES WILL CONTINUE TO RANGE BETWEEN 5-10% THROUGH AT
LEAST SATURDAY, WITH OVERNIGHT RECOVERIES ONLY REACHING 15-30%
THROUGH SATURDAY NIGHT, BEFORE IMPROVING TO 10-15% STARTING
SUNDAY. DESPITE THE DIMINISHED WINDS, SEASONABLY ELEVATED FIRE
DANGER WILL PERSIST THROUGH THE WEEKEND DUE TO VERY DRY CONDITIONS
AND VERY DRY AND RECEPTIVE FUELS. A FEW SPRINKLES AND MAYBE A
BRIEF SHOWER WILL BE POSSIBLE (5-10%) SATURDAY AFTERNOON/EVENING,
BUT WITH NO RAINFALL ACCUMULATION EXPECTED. THE MAIN IMPACT WILL
BE MAYBE SOME BRIEF GUSTY AND ERRATIC WIND SHIFTS.
..THUNDERSTORMS IMPLY GUSTY WINDS
