AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
415 PM MST TUE JUL 1 2025
SYNOPSIS
EXPECT SHOWERS AND THUNDERSTORMS TO CONTINUE INTO
THURSDAY, BEFORE DRYING AND WARMING INTO THE HOLIDAY WEEKEND.
DISCUSSION
CONVECTION HAS FORMED OVER HIGHER TERRAIN FEATURES
THIS AFTERNOON, GENERATING ROBUST OUTFLOW MOVEMENT TO THE SOUTHWEST.
THESE OUTFLOWS SHOULD LIGHT UP YAVAPAI COUNTY WITHIN THE NEXT FEW
HOURS, WITH THE NORTHERN ZONES CLEARING AND STABILIZING INTO THE
EVENING.
OUR OVERALL PATTERN REMAINS THE SAME, SOUTHERLY FLOW AND EASTERLY
OUTFLOWS WILL CONTINUE TO RAISE DEW POINTS AND PW, PEAKING DURING
THE DAY WEDNESDAY. AT THE SAME TIME, A CLOSED LOW OFF THE CENTRAL
CALIFORNIA COAST WILL EJECT EASTWARD, INJECTING SOME DYNAMICS INTO
THE SITUATION BY WEDNESDAY AFTERNOON. SHOULD BE AN ACTIVE DAY AS A
RESULT, WITH ISOLATED SEVERE AND SOME STORMS APPROACHING FLASH FLOOD
GUIDANCE FOR THE REGION.
BEHIND THIS EJECTING LOW, MUCH DRIER AND STABLE AIR MOVES IN FOR
THURSDAY AND ESPECIALLY FRIDAY, WITH A RAPID DECREASE IN ACTIVITY.
BUILDING HGHTS ALOFT BRING A WARMING TREND FOR THE HOLIDAY WEEKEND
AND INTO NEXT WEEK. WHETHER OR NOT THESE THUNDERSTORMS WILL RETURN
IS THE QUESTION, LOW CONFIDENCE AT THIS TIME THAT ANY SIGNIFICANT
ACTIVITY WILL REDEVELOP.
