AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
435 AM MST MON JUN 30 2025
SYNOPSIS
HOT AND MOSTLY DRY CONDITIONS CONTINUE THROUGH TUESDAY,
WITH INCREASING MOISTURE EXPECTED OVER THE NEXT SEVERAL DAYS. DAILY
CHANCES FOR SHOWERS AND THUNDERSTORMS, WITH INCREASING COVERAGE EACH
DAY. DRIER CONDITIONS RETURN FOR THE END OF THE WEEK.
DISCUSSION...TODAY THROUGH TUESDAY
THE RIDGE WILL REMAIN ACROSS
THE DESERT SOUTHWEST TODAY, AS THE HIGH SETTLES IN OVER NEW MEXICO.
A MOSTLY DRY AIRMASS REMAINS ACROSS THE REGION, WITH CONTINUED HOT
CONDITIONS ACROSS THE REGION. DAYTIME HIGHS EXCEEDING 110 DEGREES
ARE EXPECTED THROUGH TUESDAY IN THE LOWER ELEVATIONS OF THE GRAND
CANYON AND THE EXTREME HEAT WARNING REMAINS IN EFFECT FOR AREAS
BELOW 4000 FEET IN THE GRAND CANYON THROUGH TUESDAY. IN OTHER PARTS
OF THE REGION IT WILL REMAIN HOT SO PLEASE EXERCISE CAUTION IF
SPENDING TIME OUTSIDE. BE SURE TO STAY HYDRATED AND FIND SHADE TO
COOL YOURSELF DOWN IF YOU ARE OUTSIDE DURING PEAK HEAT TODAY.
LINGERING MOISTURE CONTINUES TO PUSH IN FROM THE SOUTH AND THIS WILL
AID IN THE DEVELOPMENT OF SOME HIGH-BASED SHOWERS AND THUNDERSTORMS
THIS AFTERNOON OVER THE WHITE MOUNTAINS AND INTO THE EASTERN
MOGOLLON RIM. SHOWER AND THUNDERSTORM COVERAGE WILL INCREASE ON
TUESDAY ACROSS THE MOGOLLON RIM, WHITE MOUNTAINS, CHUSKA MOUNTAINS,
AND INTO PARTS OF YAVAPAI COUNTY. WHILE WE TYPICALLY SEE ACTIVITY
DROP OFF AFTER SUSNET, HI-RES MODELS CONTINUE TO INDICATE THAT WE
COULD SEE SHOWERS AND STORMS CONTINUE THROUGH LATE TUESDAY AND INTO
THE OVERNIGHT HOURS. CLOUDS WILL INCREASE ACROSS THE HIGHER TERRAIN
TODAY, BUT WITH THE SUB-CLOUD LAYER REMAINING VERY DRY, WE ARE
UNLIKELY TO SEE MUCH MORE THAN VIRGA OR SOME SPRINKLES TODAY BUT
COULD LEAD TO SOME DRY THUNDERSTORMS ACROSS THE AREA.
WEDNESDAY THROUGH THURSDAY...THE RIDGE SETTLES TO OUR EAST, KEEPING
A GOOD SOUTHERLY FETCH ACROSS THE REGION THROUGH THE MIDDLE OF THE
WEEK. WIDESPREAD SHOWERS AND THUNDERSTORMS ARE EXPECTED EACH DAY AS
MOISTURE SURGES INTO THE REGION. ONCE AGAIN, WE MAY NOT SEE THE
TYPICAL DROP OFF WEDNESDAY NIGHT AS HI-RES MODELS CONTINUE TO
INDICATE SHOWERS AND STORMS PERSISTING INTO THE OVERNIGHT HOURS. AS
THE MOISTURE STARTS TO WANE SOME ON THURSDAY, WE SHOULD SEE MOST
ACTIVITY DROP OFF AFTER SUNSET. INCREASED CLOUD COVER SHOULD HELP TO
KEEP TEMPERATURES A BIT COOLER THAN THEY HAVE BEEN THE PAST SEVERAL
DAYS.
FRIDAY THROUGH THE WEEKEND...AS WE GO TOWARDS THE END OF THE WEEK,
THE TROUGH/LOW STARTS TO WEAKEN AND LIFTS TO THE NORTH AND EAST.
THIS WILL BRING ABOUT A SHIFT IN WINDS TO A MORE WESTERLY FLOW,
ALLOWING FOR SOME DRIER AIR TO FLOW INTO THE REGION. SOME MOISTURE
MAY LINGER ACROSS EASTERN AREAS INTO THE WEEKEND WITH ISOLATED
ACTIVITY OVER THE WHITE MOUNTAINS. THE TROUGH LIFTS OUT RATHER
QUICKLY AND WE SEE THE HIGH START TO REESTABLISH ITSELF AND PUSH TO
THE WEST. THIS WILL AGAIN ALLOW FOR A MORE SOUTHWEST TO SOUTH FLOW
ACROSS THE STATE AND THE RETURN OF SOME MOISTURE BY SUNDAY.
SOMETHING TO KEEP AN EYE ON AS WE LOOK TO STAY IN A MORE ACTIVE
PATTERN OVER THE NEXT WEEK OR SO.
