NWS Flagstaff, AZ wrote its last area forecast discussion before the first event at Jul 3, 3:00 PM MST, 1 hour 15 minutes earlier.
NORTHERN ARIZONA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FLAGSTAFF AZ 300 PM MST TUE JUL 03 2001 SYNOPSIS...HIGH PRESSURE ALOFT WILL STRENGTHEN OVER THE NEXT FEW DAYS AND RESULT IN A MORE STABLE ATMOSPHERE OVER NORTHERN ARIZONA. EXPECT ONLY ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ON THE FOURTH OF JULY. THE AIR MASS WILL ONCE AGAIN BECOME MORE MOIST AND UNSTABLE LATER IN THE WEEK WITH AN INCREASE IN THUNDERSTORM ACTIVITY. DISCUSSION...THE HIGH ALOFT OVER THE FOUR CORNERS REGION CONTINUES TO STRENGTHEN AND GEOPOTENTIAL HEIGHTS ARE EXPECTED TO APPROACH 600 DAM OVER THE NEXT DAY OR TWO. THE STRONG SUBSIDENCE ASSOCIATED WITH THIS STRENGTHENING HAS STABILIZED THE ENVIRONMENT WITH WARMER TEMPERATURES ALOFT AND MODERATE DRYING. SINCE THERE HAS NOT BEEN MUCH IN THE WAY OF LOW-LEVEL MOISTURE IN THE REGION...THIS LOSS OF MID LEVEL MOISTURE HAS HAD A SIGNIFICANT IMPACT ON CONVECTIVE ACTIVITY ACROSS THE REGION TODAY. EXPECT THIS PATTERN TO HOLD FOR A DAY OR TWO WITH ONLY ISOLATED TO SCATTERED CONVECTIVE ACTIVITY DEVELOPING OVER THE HIGHER TERRAIN AND THEN MOVING INTO THE LOWER ELEVATIONS LATER IN THE DAY. THE HIGH BEGINS TO SHIFT FROM THE FOUR CORNERS REGION TO EASTERN NM LATER IN THE WEEK AND EXPECT THE FLOW TO VEER FROM THE EAST TO THE SOUTH. THIS SHOULD PRODUCE A GRADUAL INCREASE IN MOISTURE AND CONVECTIVE ACTIVITY. THERE IS SOME HINT OF ANOTHER DRYING TREND LATE IN THE EXTENDED BUT GIVEN THE UNCERTAINTIES IN THE LONG RANGE MODELS AT THIS TIME OF YEAR WILL GROUP ALL DAYS TOGETHER AND GO WITH A CHANCE OF SHOWERS EACH DAY. DB .FGZ...NONE.
