AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
341 PM MST MON MAY 11 2026
SYNOPSIS
WARM TEMPERATURES AND MOSTLY DRY WEATHER WILL CONTINUE
THROUGH THE WEEK. ISOLATED SHOWERS ARE POSSIBLE ACROSS THE HIGHER
TERRAIN AROUND THE MIDDLE OF THE WEEK, ALONG WITH SLIGHTLY COOLER
TEMPERATURES AND ENHANCED SOUTHWESTERLY BREEZES.
DISCUSSION
VERY DRY AND WARM CONDITIONS CONTINUE TODAY, WITH
VERY LITTLE GRADIENT-DRIVEN WIND. WARM AND DRY WEATHER IS EXPECTED
AGAIN TUESDAY, BUT SOUTHWEST WINDS WILL START TO INCREASE AHEAD OF
ANOTHER S/WV TROUGH DUE ON WEDNESDAY. EXPECT MID-LEVEL MOISTURE TO
INCREASE ENOUGH ON TUESDAY FOR SOME FAIR-WEATHER CU/SC IN THE
AFTERNOON.
THE TROUGH ENTERS THE NORTHERN GREAT BASIN BY LATE WEDNESDAY. THIS
TROUGH IS FARTHER NORTH, COMPARED TO PREVIOUS SOLUTIONS, SO IMPACTS
WILL BE MINIMAL. ONE THING TO WATCH IS ENHANCED SOUTHWEST WINDS ON
WEDNESDAY, AHEAD OF THE TROUGH. SPEEDS WILL LIKELY REACH NEAR WIND
ADVISORY CRITERIA AND ALONG WITH A CONTINUED DRY BOUNDARY LAYER.
LOCALIZED NEAR-CRITICAL FIRE WEATHER CONDITIONS ARE POSSIBLE.
ALSO FOR WEDNESDAY, EXPECT A FURTHER INCREASE CU/SC ACTIVITY, WITH
EVEN A STRAY SHOWER OR THUNDERSTORM POSSIBLE WEDNESDAY AFTERNOON.
BEHIND THE TROUGH AXIS, EXPECT SOME COOLING FOR THE REST OF THE
WEEK, HOWEVER, DAYTIME TEMPERATURES WILL STILL BE ABOVE NORMAL.
A ZONAL, BUT WARM AND CONTINUED DRY PATTERN THEN PERSISTS INTO THE
COMING WEEKEND.
