AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
230 AM MST WED APR 22 2026
SYNOPSIS
DRY, BREEZY, AND COOLER CONDITIONS EXPECTED THROUGH THE
END OF THE WEEK. GUSTY SOUTHWEST WINDS EACH DAY WITH THE STRONGEST
WINDS TODAY WHEN A WIND ADVISORY AND RED FLAG WARNING ARE IN EFFECT.
UNSETTLED WEATHER RETURNS FOR THE WEEKEND.
DISCUSSION
A STRONG PACIFIC LOW IS MAKING ITS WAY INTO THE
PACIFIC NORTHWEST EARLY THIS MORNING. WITH THE WEAK RIDGE PUSHING
FURTHER TO THE EAST, WE FIND OURSELVES GETTING SQUEEZED BETWEEN THE
TWO SYSTEMS, RESULTING IN STRENGTHENING SOUTHWESTERLY WINDS ACROSS
ARIZONA. AS THE TROUGH AXIS OF THE LOW MOVES ACROSS OUR AREA, WE
WILL SEE WINDS BECOME VERY GUSTY, ESPECIALLY ALONG AND NORTHEAST OF
THE MOGOLLON RIM, WHERE WINDS WILL BE AROUND 20-35 MPH WITH GUSTS UP
TO 50 MPH. SOME LOCALIZED GUSTS TO 60 MPH ARE POSSIBLE THROUGH THIS
AFTERNOON AND EVENING. A WIND ADVISORY IS IN EFFECT FOR PORTIONS OF
THE FORECAST AREA FOR TODAY DUE TO THESE STRONG WINDS. ADDITIONALLY,
CONDITIONS ARE VERY DRY, ESPECIALLY ACROSS NORTHEASTERN ARIZONA,
WHICH RAISES FIRE WEATHER CONCERNS. A RED FLAG WARNING IS IN EFFECT
FOR NAVAJO NATION AND THE LITTLE COLORADO RIVER VALLEY FOR TODAY.
THE LOW WILL CONTINUE ITS EASTWARD PUSH INTO THE NORTHERN ROCKIES BY
LATER TODAY. THE FLOW TURNS MORE ZONAL, WESTERLY, ACROSS ARIZONA FOR
THURSDAY AND FRIDAY. THE GRADIENT WILL REMAIN TIGHT THROUGH
WEDNESDAY NIGHT WITH SOME AREAS SEEING GUSTS CONTINUE OVERNIGHT.
EVEN THOUGH THE GRADIENT LOOKS TO WEAKEN ON THURSDAY, IT WILL STILL
REMAIN BREEZY WITH WESTERLY WINDS 10-20 MPH AND GUSTS TO 25-30 MPH.
EXPECT SIMILAR WINDS TO CONTINUE ON FRIDAY. A WEAK SHORTWAVE WILL
PASS THROUGH ON FRIDAY BUT ALL THAT WILL BRING FOR US IS SOME
ADDITIONAL CLOUD COVER. TEMPERATURES WILL COOL SLIGHTLY BUT REMAIN
NEAR AVERAGE ACROSS THE REGION.
THE WEEKEND LOOKS UNSETTLED AS SEVERAL SHORTWAVES MOVE THROUGH THE
MID-LEVEL FLOW. MOISTURE BEGINS TO INCREASE ON SATURDAY AND WILL DO
SO WITH SUBSEQUENT WAVE THAT MOVES THROUGH THE REGION. EXPECT
INCREASING CLOUDINESS WITH SOME CHANCES FOR SHOWERS OVER THE WEEKEND
AND INTO NEXT WEEK. TEMPERATURES WILL COOL AND REMAIN NEAR TO BELOW
AVERAGE AND WE WILL SEE THOSE AFTERNOON BREEZES CONTINUE.
