AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
230 PM MST WED MAR 04 2015

.SYNOPSIS....HIGH PRESSURE WILL BUILD ACROSS THE WESTERN STATES OVER
THE COMING DAYS. LOOK FOR GRADUALLY WARMING DAYTIME TEMPERATURES AND
FAIR WEATHER ACROSS NORTHERN ARIZONA THROUGH THE COMING WEEKEND.

&&

.DISCUSSION...
HIGH PRESSURE ALOFT WAS BUILDING ALONG THE WEST COAST DURING THE
AFTERNOON WHILE A WEAK LOW PRESSURE CENTER LINGERED OVER THE
SOUTHWEST UNITED STATES. OVER THE COMING DAYS, THE WEAK LOW WILL
CONTINUE LINGERING OVER NEW MEXICO/SOUTHERN ARIZONA BUT HAVE LITTLE
IMPACT OTHER THAN A FEW AFTERNOON CUMULUS CLOUDS OVER EASTERN
ARIZONA. THE MORE IMPORTANT INFLUENCE WILL BE A LONGWAVE RIDGE OF
HIGH PRESSURE BUILDING OVER THE WESTERN UNITED STATES. UNDER THE
INFLUENCE OF THIS HIGH A MILDER AIR MASS WILL MOVE ACROSS NORTHERN
ARIZONA. THE NET RESULT WILL BE WARMING DAYTIME TEMPERATURES, MAINLY
CLEAR SKIES AND FAIR WEATHER LASTING INTO EARLY NEXT WEEK. IN
ADDITION, THE INVERSION ALOFT WILL REMAIN FAIRLY WEAK WITH DECENT
MIXING OF DRIER AIR TO THE SURFACE EACH AFTERNOON. SO, EVEN WITH THE
VERY MOIST GROUND CONDITIONS, MIXING WILL INHIBIT MOISTENING OF THE
BOUNDARY LAYER AND PRODUCE A VERY LOW POTENTIAL FOR FOG FORMATION.
