NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
915 AM MST WED AUG 28 2002

.SYNOPSIS...LOW PRESSURE OVER THE NORTHERN GREAT BASIN ALONG WITH
HIGH PRESSURE OVER NEW MEXICO WILL PRODUCE GUSTY SOUTHWEST WINDS
OVER NORTHERN ARIZONA TODAY. SOME MOISTURE FROM MEXICO WILL ALSO BE
DRAWN NORTHEASTWARD...RESULTING IN ISOLATED THUNDERSTORMS FROM
FLAGSTAFF EASTWARD TODAY. LOCALLY BREEZY CONDITIONS WEST AND CENTRAL
PORTIONS AND A CHANCE OF THUNDERSTORMS IN THE EAST WILL CONTINUE
INTO THE WEEKEND.

.DISCUSSION...MAIN CONCERN TODAY WILL BE WINDS. NRN AZ REMAINS
BETWEEN TROF OVER NORTHERN GREAT BASIN AND HIGH PRESSURE TO THE EAST
OF THE STATE. NO FGZ SOUNDING BUT PHX SOUNDING INDICATES 30-40 KT OF
WIND ALOFT FOR GUSTY WINDS TODAY. REMAINING MIXED LAYER FROM
YESTERDAY WILL ALLOW US TO MIX RAPIDLY INTO THIS WIND FIELD FOR
EARLY START TO WINDS. STRONGEST WINDS ARE EXPECTED OVER THE WESTERN
HALF OF THE CWA AND LCR. THIS EVENT LOOKS AS THOUGH RED FLAG
CRITERIA WILL BE MET...BUT NOT LIKELY TO MEET PUBLIC WIND ADVISORY
CRITERIA. TROF FILLS ON THURSDAY AND GRADIENTS RELAX FOR LIGHTER
WINDS.

OTHER STORY WILL BE THE INFUSION OF MOISTURE THAT HAS MOVED INTO
MOST OF THE FORECAST AREA OVERNIGHT DUE TO MCS OVER NORTHERN MEXICO.
DEW POINTS UP 10 DEGREES OR MORE IN THE EAST AND TUS SOUNDING HAS
MORE THAN DOUBLED IN PRECIPITABLE WATER WITH AMPLE CONVECTIVE ENERGY
IN THE SOUNDING. SHOWERS HAVE STARTED ALREADY OVER THE WHITES SO
WILL BRING POPS UP OVER THIS REGION FOR TODAY. EXPECT ANOTHER MCS TO
DEVELOP LATER THIS AFTERNOON AND STEERING FLOW PUSHES THIS MOISTURE
NORTHEASTWARD OVER THE WHITES OVERNIGHT FOR CONTINUED CHANCE OF
THUNDERSTORMS.  STAUDENMAIER

.FGZ...NONE.

BRIEF GUSTY WINDS MAY ACCOMPANY SOME OF THESE THUNDERSTORMS
...ESPECIALLY THIS AFTERNOON.
