NATIONAL WEATHER SERVICE FLAGSTAFF AZ
106 PM MST SUN OCT 5 2025
SYNOPSIS
EXPECT PLEASANT FALL-LIKE WEATHER FOR THE FIRST HALF
OF THE WEEK. UNSETTLED CONDITIONS WITH PRECIPITATION CHANCES
RETURN TO THE AREA DURING THE SECOND HALF OF THE WEEK AND LAST
THROUGH THE WEEKEND.
DISCUSSION
SOUTHWESTERLY FLOW ALOFT GENERATED BY A RIDGE TO OUR
SOUTHEAST AND A TROUGH OVER THE EASTERN PACIFIC WILL KEEP
PLEASANT FALL WEATHER OVER THE REGION FOR THE FIRST HALF OF THE
WEEK. TEMPERATURES WILL BE AT SEASONAL AVERAGES FOR MONDAY BUT
WARM TO ABOUT 5 DEGREES ABOVE AVERAGE FOR THE REST OF THE WEEK.
WITH THE DRY AIR IN PLACE AND LIGHT TO NONEXISTENT WINDS AT NIGHT,
OVERNIGHT TEMPERATURES ONCE AGAIN WILL TAKE A NOSEDIVE TONIGHT
AND TOMORROW BEFORE MODERATING A LITTLE AS THE WEEK PROGRESSES.
STILL MANY QUESTIONS EXIST ON HOW THINGS WILL TURN OUT STARTING ON
THURSDAY. IT WILL ALL BE DEPENDENT ON WHEN AND HOW MUCH MOISTURE
GETS DRAWN NORTH FROM TROPICAL CYCLONE PRISCILLA AND THE ARRIVAL
OF THE NEXT WEST COAST TROUGH. STILL SOME SLIGHT POPS FOR THINGS
TO OCCUR THURSDAY INTO FRIDAY, MAINLY FAVORING THE NORTHWESTERN
HALF OF ARIZONA. BETTER POPS ARE SHOWING UP OVER THE WEEKEND AS
THE WEST COAST TROUGH SLOWLY MOVES THROUGH PROVIDING THE NEEDED
DYNAMICS. STILL WAITING ON SOME BETTER MODEL AGREEMENT BEFORE WE
LOOK AT ADVERTISING ANY WEATHER HEADLINES AND IMPACTS.
