FIRE WEATHER PLANNING FORECAST FOR SOUTHWEST AND SOUTH-CENTRAL
ARIZONA AND SOUTHEAST CALIFORNIA
NATIONAL WEATHER SERVICE PHOENIX AZ
126 PM MST SAT JUL 11 2026
DISCUSSION
SHOWER AND THUNDERSTORM ACTIVITY WILL INCREASE AS WE GO THROUGH
THE WEEKEND, GOING FROM ISOLATED OVER THE FAR EASTERN DISTRICTS
THIS AFTERNOON AND EVENING TO MORE WIDESPREAD FOR TYPICAL
MOUNTAIN AREAS, AND EVEN THE LOWER DESERTS EAST OF THE COLORADO
RIVER, LATER ON SUNDAY. THE GREATER COVERAGE OF STORMS WILL
PRESENT SOME FIRE WEATHER CONCERNS, BUT IN TURN, IT ALSO MEANS
INCREASE MOISTURE LEVELS FOR THE REGION. MINRHS ARE EXPECTED TO
HOVER BETWEEN 15-25% THIS WEEKEND, WHILE OVERNIGHT RECOVERY WILL
OFFER DECENT TO GOOD RELIEF AS RHS RISE TO BETWEEN 35-70%. OUTSIDE
OF POTENTIAL THUNDERSTORM OUTFLOWS, WINDS WILL FAVOR DIURNAL
TRENDS WITH TYPICAL AFTERNOON BREEZINESS BETWEEN 20-25 MPH.
..THUNDERSTORMS IMPLY GUSTY WINDS
