AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
836 AM MST SUN MAR 30 2025
SYNOPSIS
COOL AND BREEZY CONDITIONS WILL CONTINUE THROUGH MONDAY.
A MORE UNSETTLED PATTERN WITH CHANCES FOR SHOWERS EXPECTED THROUGH
THE REST OF THE WEEK.
UPDATE
MILD AND BREEZY WEATHER IS IN STORE FOR TODAY. WE CAN'T
RULE OUT THE POSSIBILITY OF A FEW SPRINKLES HITTING THE GROUND IN
FAR NORTHERN ARIZONA, BUT THAT WILL BE THE MAIN MOISTURE IMPACT
FROM THE WEAK PASSING TROUGH THIS AFTERNOON. THE FORECAST REMAINS
IN GOOD SHAPE, SO NO SHORT-TERM UPDATES WERE NEEDED.
PREV DISCUSSION /433 AM MST/...TODAY
A TROUGH WILL MOVE THROUGH THE REGION TODAY,
BRINGING MORE GUSTY WINDS TO THE REGION. A FEW SPRINKLES ARE
POSSIBLE TOWARDS THE AZ/UTAH BORDER BUT THIS TROUGH IS VERY MOISTURE
STARVED AND EVEN SPRINKLES WILL BE LIMITED. AS THE TROUGH MOVES
THROUGH WE SHOULD SEE THE CLOUDS CLEARING OUT FROM WEST TO EAST,
WITH SOME AREAS FINALLY BECOMING MOSTLY SUNNY BY THIS AFTERNOON.
SOUTHWEST WINDS 15-25 MPH WITH GUSTS 30-35 MPH ARE EXPECTED. DAYTIME
HIGHS WILL BE NEAR AVERAGE.
MONDAY...WHILE WE SHOULD SEE BRIEF RIDGING ACROSS THE REGION ON
MONDAY, THE GRADIENT REALLY STARTS TO TIGHTEN IN ADVANCE OF THE NEXT
TROUGH. WINDS WILL BECOME QUITE GUSTY AS A STRONG JET CROSSES THE
REGION. SOUTHWEST WINDS WILL INCREASE THROUGH THE MORNING, BECOMING
20-30 MPH WITH GUSTS UP TO 50 MPH ACROSS MUCH OF NORTHERN ARIZONA. A
WIND ADVISORY HAS BEEN ISSUED FOR AREAS WHERE WINDS WILL BE THE
STRONGEST. EXPECT SOME OF THE HIGHER GUSTS WILL BE IN AREAS THAT ARE
JUST NORTH AND EAST OF THE HIGHER TERRAIN. THE ADVISORY RUNS FROM 11
AM MST (NOON MDT) THROUGH 2 AM MST (3 AM MDT).
TUESDAY THROUGH THE END OF THE WEEK...A DEEPENING TROUGH WILL START
TO PUSH SOUTHWARD INTO ARIZONA ON TUESDAY AND WILL REMAIN OVER THE
SOUTHWESTERN STATES THROUGH THE WEEK. THIS TROUGH AND EVENTUALLY THE
DEVELOPING CLOSED LOW WILL BRING CHANCES FOR RAIN AND SNOW SHOWERS
THROUGH THE COURSE OF THE WEEK. THIS DEEPENING TROUGH WILL BRING
MORE GUSTY WINDS, ESPECIALLY ON TUESDAY, AND ADDITIONAL WIND
HEADLINES WILL LIKELY BE NEEDED, MAINLY ACROSS EASTERN ARIZONA.
COLDER AIR WILL FILTER DOWN INTO THE REGION DROPPING TEMPERATURES TO
AROUND 10-15 DEGREES BELOW AVERAGE. MODELS CONTINUE TO STRUGGLE WITH
THE EVOLUTION OF THIS TROUGH. THERE ARE STILL MANY ISSUES WITH THIS
SYSTEM WITH TIMING, STRENGTH, AND MOISTURE SO WE WILL NEED TO
CONTINUE MONITORING THIS IN THE COMING DAYS. JUST KNOW IT LOOKS LIKE
WE WILL SEE RAIN/SNOW ACROSS THE REGION WITH COLDER TEMPERATURES
THAN WE TYPICALLY SEE THIS TIME OF YEAR.
