AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
410 PM MST THU SEP 10 2026
SYNOPSIS
CHANCES FOR SHOWERS AND THUNDERSTORMS INCREASE FOR
FRIDAY AND INTO THE WEEKEND, ALONG WITH A MODEST COOLING TREND AND
BREEZY SOUTHWEST WINDS.
DISCUSSION
MONSOON MOISTURE WILL RETURN AS EARLY AS TOMORROW AS
HIGH PRESSURE REESTABLISHES ITSELF OVER ARIZONA. WE HAVE ENTERED THE
SHOULDER SEASON, SO THE MOISTURE POOL WILL OCCASIONALLY RETREAT AND
THEN MOVE BACK NORTHWARD AS IT INTERACTS WITH TROUGHS FOR THE NEXT
SEVERAL WEEKS. EVENTUALLY, THESE TROUGHS WILL SWEEP THE MOISTURE OUT
PERMANENTLY, BUT THIS LOOKS LIKE IT IS AT LEAST 10 DAYS OUT.
SOUTHWEST BREEZES WILL ALSO PICK UP OVER THE NEXT FEW DAYS AS LOW
PRESSURE PASSES TO OUR NORTH, BUT NOTHING THAT WILL NEED ANY
HEADLINES.
SO, THIS IS THE LAST VERY WARM DAY, EXPECT SOME COOLING AS SHOWERS
PICK UP HEADING INTO THE WEEKEND. WE SHOULD DIP BACK TO NORMAL
AROUND MONDAY OR TUESDAY.
