NATIONAL WEATHER SERVICE FLAGSTAFF AZ
942 PM MST SUN MAY 31 2026
SYNOPSIS
WARMING TEMPERATURES AND LIGHTER WINDS ARE EXPECTED
THIS WEEK. MOST AREAS WILL REMAIN DRY, BUT CHANCES FOR SHOWERS
AND THUNDERSTORMS INCREASE BY THE MIDDLE OF THE WEEK, MAINLY FOR
SOUTHERN NAVAJO AND APACHE COUNTIES.
DISCUSSION
A DRY SOUTHWEST FLOW ALOFT WILL CONTINUE FOR OUR AREA
THROUGH MONDAY WITH WEAK TROUGHING TO OUR WEST/NORTHWEST AND A RIDGE
OVER THE SOUTHERN PLAINS/TEXAS. DAYTIME TEMPERATURES WILL BE A FEW
DEGREES WARMER EACH DAY, WITH RELATIVELY LIGHT WINDS.
TUESDAY THROUGH THURSDAY - AN INCREASE IN MOISTURE IS FORECAST OVER
THE EASTERN 1/3 OF THE STATE ESPECIALLY SOUTHERN APACHE AND
NAVAJO COUNTIES. THIS IS IN RESPONSE TO A BRIEF PERIOD OF
SOUTH/SOUTHEAST FLOW ALOFT AS THE WEAK TROUGH APPROACHES FROM THE
WEST. ENSEMBLE MEAN PRECIPITABLE WATER VALUES ARE IN THE
0.50"-0.60" RANGE OVER THIS AREA, PEAKING WED/THU. THESE VALUES
ARE DOWN SLIGHTLY FROM 24 HRS AGO. SHOWER AND THUNDERSTORM CHANCES
ARE LIMITED TO AROUND 20% FOR THE WHITE MTNS REGION TUESDAY,
INCREASING TO 30-60% WED/THU WITH 10-20% CHANCES SPREADING INTO
THE CHUSKA MTNS/WINDOW ROCK AREA. ELSEWHERE, THE MID LEVEL
MOISTURE INCREASE SHOULD BE ENOUGH FOR SOME AFTERNOON HIGH-BASED
CUMULUS, BUT PRECIPITATION IS NOT EXPECTED. DAYTIME TEMPERATURES
WILL BE WITHIN A FEW DEGREES OF NORMAL, WITH TYPICAL EARLY JUNE
WINDS OF 5-15 MPH WITH GUSTS AROUND 20 MPH.
FRIDAY INTO NEXT WEEKEND - DRIER SOUTHWEST FLOW IS FORECAST TO
RETURN AS TROUGHING DEVELOPS AGAIN TO OUR WEST. INCREASING SOUTHWEST
WINDS AND A BIT COOLER TEMPERATURES COULD DEVELOP AS THE TROUGH
APPROACHES TOWARD THE WEEKEND.
