AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
330 PM MST SAT APR 19 2008

.SYNOPSIS...A TROUGH OF LOW PRESSURE WILL CONTINUE TO SLOWLY MOVE
ACROSS THE WESTERN UNITED STATES. THIS WEATHER PATTERN WILL KEEP
TEMPERATURES NEAR TO SLIGHTLY ABOVE NORMAL AND PRODUCE PERIODS OF
BREEZY WINDS THROUGH FRIDAY. STRONG WINDS WITH GUSTS RANGING FROM 35
TO 50 MPH WILL CONTINUE THIS AFTERNOON INTO EARLY EVENING THEN
DIMINISH OVERNIGHT. BREEZY WINDS WILL RETURN TOMORROW MORNING A FEW
HOURS AFTER SUNRISE WITH STRONGER GUSTS IN THE AFTERNOON RANGING
FROM 30 TO 40 MPH.

&&

.DISCUSSION...A WIND ADVISORY AND RED FLAG WARNING REMAIN IN EFFECT
ACROSS MOST OF NORTHERN ARIZONA THROUGH 7 PM TONIGHT. WINDS ARE
EXPECTED TO DIMINISH AFTER SUNSET AS THE VERTICAL MIXING LAYER
DECREASES.

A LONG WAVE TROUGH WILL REMAIN IN PLACE OVER THE WESTERN UNITED
STATES THROUGH THE MIDDLE OF NEXT WEEK. SEVERAL SHORT WAVE TROUGHS
WILL MOVE ALONG THIS UPPER LEVEL PATTERN...CAUSING LOCAL AREA
PRESSURE GRADIENTS TO TIGHTEN AND PRODUCING PERIODS OF BREEZY WINDS
ACROSS MUCH OF THE NORTHLAND. BOTH THE EUROPEAN AND GFS MODELS
CONTINUE TO BE IN GOOD AGREEMENT THROUGH MID WEEK WITH THE TIMING
AND INTENSITY OF THESE SHORT WAVE TROUGHS. HOWEVER...FORECAST
CONFIDENCE IN RUN TO RUN CONSISTENCY IS ONLY FAIR AND THE TIMING OF
THESE SHORT WAVES SEEMS TO CHANGE SLIGHTLY WITH EACH NEW MODEL RUN.

THE FORECAST THROUGH WEDNESDAY CALLS FOR PERIODS OF BREEZY
WINDS WITH HIGHER WIND GUSTS IN THE AFTERNOON. COOLER AIR ALOFT
ASSOCIATED WITH THIS LONG WAVE TROUGH PATTERN WILL KEEP OUR
TEMPERATURES NEAR TO SLIGHTLY ABOVE NORMAL LEVELS WITH NO CHANCES
FOR PRECIPITATION IN THE FORECAST.

&&

.AVIATION...FOR THE 00Z PACKAGE...AN APPROACHING LOW PRESSURE SYSTEM
WILL BRING GUSTY SOUTH-SOUTHWEST WINDS OF 20-30 KTS WITH GUSTS OF 40
TO 45 KTS THIS AFTERNOON. WINDS WILL BEGIN TO DECREASE BY 02Z-03Z...
REMAINING IN THE 10-20 KT RANGE OVERNIGHT. WINDS WILL INCREASE AGAIN
AFTER 15Z SUNDAY...WITH SUSTAINED SPEEDS OF 20-25 KT GUSTING TO
30-35 KT. OTHERWISE...EXPECT VFR CONDITIONS. AVIATION DISCUSSION NOT
UPDATED FOR AMENDMENTS.
&&

.FIRE WEATHER...RED FLAG WARNING IN EFFECT UNTIL 7 PM MST THIS
EVENING FOR NORTHERN ARIZONA. FIRE WEATHER WATCH IN EFFECT FROM 9 AM
MST UNTIL 7 PM MST SUNDAY FOR NORTHERN ARIZONA. SEE PHXRFWFGZ FOR
DETAILS. SEE PHXFWFFGZ FOR FURTHER DISCUSSION OF DAYS 1 AND 2.

FOR TUESDAY THROUGH THURSDAY...DRY WESTERLY FLOW WILL CONTINUE OVER
NORTHERN ARIZONA WITH LOW AFTERNOON HUMIDITY...ABOVE NORMAL
TEMPERATURES...AND AFTERNOON BREEZES. A WEATHER DISTURBANCE IS
FORECAST TO MOVE THROUGH THE GREAT BASIN WEDNESDAY. INCREASING WINDS
WITH THIS FEATURE MAY CREATE CRITICAL FIRE WEATHER CONDITIONS.

&&

.FGZ WATCHES/WARNINGS/ADVISORIES...A WIND ADVISORY IN EFFECT UNTIL 7
PM THIS EVENING FOR AZZ004>007-009>017-038>040.

A RED FLAG WARNING IN EFFECT THROUGH 7 PM MST THIS EVENING FOR ALL
