AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
1010 AM MST WED JUL 2 2025
SYNOPSIS
WIDESPREAD TO SCATTERED SHOWERS AND THUNDERSTORMS
THROUGH THURSDAY. DRIER AND WARMER CONDITIONS RETURN FOR THE HOLIDAY
WEEKEND.
DISCUSSION...TODAY THROUGH THURSDAY
A CLOSED LOW CONTINUES TO
REMAIN TO THE WEST OF THE AREA THIS MORNING BUT IS EXPECTED TO LIFT
AND CROSS THE REGION OVER THE NEXT 36 HOURS OR SO. WITH THE RIDGE
SITUATED TO OUR EAST, WE WILL CONTINUE TO HAVE A STRONG SOUTHERLY
FETCH AND ADVECTION OF MOISTURE INTO THE REGION. AS THE LOW PUSHES
TO THE EAST, IT WILL BRING IN SOME ENHANCED DYNAMICS AND HELP TO
PROVIDE ADDITIONAL LIFT TO THE REGION. WITH THE INCREASED MOISTURE
AND STRONG LIFT PRESENT, WE SHOULD SEE MORE WIDESPREAD STORMS. PWATS
AROUND 1.00" TODAY LEND SUPPORT TO EFFICIENT RAINMAKING STORMS
TODAY. THROW IN THE SLOWER STORM MOTION AND WE WILL SEE AN INCREASE
IN THE PROBABILITY FOR FLASH FLOODING TO OCCUR. ADDITIONALLY, SOME
OF THE STRONGER STORMS WILL SEE GUSTY WINDS AROUND 40-50 MPH AND
SMALL HAIL, WITH ISOLATED SEVERE GUSTS POSSIBLE. SIMILAR CONDITIONS
EXIST FOR THURSDAY, BUT AS THE LOW/TROUGH PUSHES FURTHER EAST, WE
WILL SEE SOME DRIER AIR START TO PUSH INTO OUR WESTERN AREAS AND
PWATS WILL DROP DOWN CLOSER TO 0.60-0.80" ACROSS THE REGION. THIS
WILL PUSH THE BETTER CHANCES FOR SHOWERS AND THUNDERSTORMS EASTWARD
THROUGH THE DAY.
FRIDAY ONWARD...AS THE LOW PASSES TO THE NORTH AND EAST, A MORE
WESTERLY FLOW DEVELOPS AND BRINGS IN SOME MUCH DRIER AIR. SOME
ISOLATED CHANCES FOR SHOWERS MAY CONTINUE ACROSS FAR EASTERN
ARIZONA, MAINLY THE WHITE MOUNTAINS, BUT EVEN THAT IS LOOKING TO BE
<10% THROUGH FRIDAY. FOR THE WEEKEND, THINGS DRY OUT FURTHER AND
LITTLE TO NO PRECIPITATION IS EXPECTED IN OUR FORECAST AREA.
TEMPERATURES WILL ALSO START TO WARM ONCE AGAIN FOR THE WEEKEND AND
WE COULD SEE TEMPERATURES NEARING 110 DEGREES IN THE LOWER
ELEVATIONS OF THE GRAND CANYON BY SUNDAY. BY THE END OF THE WEEKEND,
THE HIGH RETROGRADES AND MOVES ACROSS ARIZONA/NEW MEXICO BEFORE
SETTLING OVER THE GREAT BASIN AROUND THE MIDDLE OF NEXT WEEK. THIS
WILL BRING BACK HOT TEMPERATURES AND IS NOT REALLY A GREAT SET UP TO
KEEP SHOWERS AND THUNDERSTORMS IN OUR AREA.

WIDESPREAD -SHRA/-TSRA
FORECAST THROUGH AT LEAST 04Z. REDUCED VISIBILITIES FROM HEAVY

KTS. GUSTY/ERRATIC WINDS POSSIBLE ON THURSDAY DUE TO

GUSTS 25-30 MPH EACH DAY.
FRIDAY THROUGH SUNDAY...ISOLATED SHOWERS POSSIBLE NEAR THE
WHITE MOUNTAINS ON FRIDAY. OTHERWISE, EXPECT WARMER AND DRIER
