AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
310 PM MST TUE APR 29 2014

.SYNOPSIS...
HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE WESTERN UNITED STATES
THIS WEEK RESULTING IN WARM DRY WEATHER THROUGH ARIZONA AND
SOUTHEAST CALIFORNIA. WINDY CONDITIONS CAN BE EXPECTED AT TIMES
THROUGH THURSDAY...ESPECIALLY OVER THE COLORADO RIVER VALLEY AND
PARTS OF SOUTHEAST CALIFORNIA. TEMPERATURES WILL GRADUALLY INCREASE
TO WELL ABOVE NORMAL LEVELS BY THE END OF THE WEEK...WITH HIGHS
PEAKING IN THE UPPER 90S TO AROUND 100 IN THE LOWER DESERTS BY THE
WEEKEND.

&&

.DISCUSSION...
EARLY AFTERNOON WV IMAGERY DEPICTS WEST COAST RIDGE AMPLIFICATION
FURTHER STEEPENING WITH A SUBTROPICAL LOW NEAR 23N 125W STUCK IN
PLACE AND REMOVED FROM THE GENERAL FLOW PATTERN. SUBTROPICAL
MOISTURE ASSOCIATED WITH THE LATTER FEATURE WILL REMAIN SOUTH OF THE
FORECAST AREA AS LIMITING STREAMLINES RETARD ANY NORTHWARD
PROPAGATION. OTHERWISE...WITH THE ENTIRE NORTH AMERICAN FLOW PATTERN
REMAINING BLOCKED...THE AFOREMENTIONED RIDGE WILL CONTINUE TO
AMPLIFY AND NARROW IN WAVELENGTH THROUGH THURSDAY FORCING CONTINUED
SFC PRESSURE RISES OVER THE NRN ROCKIES/GREAT BASIN. OBJECTIVE
ANALYSIS AND OBSERVATIONAL DATA SHOWS A 1040+MB SFC HIGH SITUATED
ACROSS IDAHO...WITH PRESSURE RISES GENERALLY WANING IN A TYPICAL
DIURNAL FASHION OVER THE MAJORITY OF ARIZONA. HOWEVER...A STEEP 10MB
KTUS-KLAS SFC PRESSURE GRADIENT ALREADY EXISTS...AND WILL BE
MAINTAINED FOR THE NEXT 48 HOURS. THUS...BREEZY CONDITIONS WILL
PREVAIL THOUGH WIND ADVISORIES ARE SET TO EXPIRE THIS AFTERNOON WITH
SPOTTY LOCATIONS REACHING THRESHOLDS. FIRE WEATHER CONCERNS HAVE
BEEN MORE JUSTIFIED WITH PERSISTENT GUSTY WINDS AND RELATIVE
HUMIDITY VALUES FALLING AS LOW AS 3-4 PERCENT. WITH A NEAR REPEAT
PERFORMANCE WEDNESDAY...HEADLINES FOR DANGEROUS CONDITIONS HAVE BEEN
EXTENDED AND EXPANDED STARTING AFTER SUNRISE.

ONE NOTABLE DIFFERENCE IN MODEL OUTPUT OF LATE IS THE APPEARANCE OF
A SHORTWAVE AND LOBE OF VORTICITY ROTATING SOUTHWARD THROUGH EASTERN
ARIZONA ON THE WESTERN PERIPHERY AN IMMENSE MIDWEST CUTOFF LOW
PRESSURE SYSTEM. WHILE SOME INCREASE IN MID/UPPER LEVEL MOISTURE
WOULD BE LIKELY IN THE FORM OF CLOUD COVER...THE MOST SALIENT
EFFECTS TO SENSIBLE WEATHER WILL BE PROLONGED SHARP ANTI-CYCLONIC
FLOW FORCING PERSISTENT UPSTREAM SFC PRESSURE RISES (HENCE CONTINUED
GUSTY WINDS)...AND A SUBTLE DELAY IN THE OVERALL WARMING TREND AS
THE COLD CORE ALOFT GRAZES THE REGION.

FRIDAY THROUGH MONDAY...
THE FLOW PATTERN OVER NORTH AMERICA SHIFTS TOWARD LESS AMPLIFICATION
BEGINNING FRIDAY AS THE DOWNSTREAM BLOCK BREAKS DOWN. THIS ENABLES
WARMER AIR TO MOVE FURTHER INLAND FOR WARMER TEMPERATURES FRIDAY AND
SATURDAY AND LITTLE CHANGE SUNDAY. THIS WILL TAKE US WELL ABOVE
NORMAL. MADE ONLY SUBTLE TWEAKS TO NUMBERS FROM PREVIOUS PACKAGE.
THUS HELD OFF ON 100 FOR SKY HARBOR SATURDAY BUT WE WILL BE CLOSE.
DIFFERENCES BETWEEN THE ECWMF AND GFS BECOME LARGER EARLY NEXT WEEK
AS THEY HANDLE THE FLOW PATTERN OVER THE PACIFIC DIFFERENTLY. THE
ECMWF AND GEM FAVOR MORE ZONAL FLOW OVER NORTH AMERICA WHILE THE GFS
DIGS A PACIFIC NORTHWEST TROUGH FURTHER SOUTH. THE ENSEMBLE MEANS
GENERALLY SUPPORT THE RESPECTIVE OPERATIONAL RUNS. SHOWED SOMEWHAT
COOLER TEMPS FOR MONDAY LEANING TOWARD EC PER NCEP DISCUSSION.

&&

.AVIATION...
SOUTH-CENTRAL ARIZONA INCLUDING KPHX...KIWA...AND KSDL...
LATEST OBSERVATIONS INDICATE THAT WINDS AS STRONG AS 35 KT ARE
PREVALENT AT 2-3K FT...WHICH IS RESULTING IN LOCALIZED LOW-LEVEL
WIND SHEAR. GUSTS AS HIGH AS 30 KT HAVE BEEN OBSERVED AT KSDL THIS
MORNING AND WINDY CONDITIONS WILL PERSIST THROUGHOUT THE DAY.
INITIALLY GUSTS WILL BE CONCENTRATED ALONG FOOTHILL LOCATIONS...BUT
BY 15-16Z GUSTS TO 25 KT WILL BECOME WIDESPREAD ACROSS THE PHOENIX
AREA. ALTHOUGH WINDS WILL DIMINISH SOMEWHAT AFTER SUNSET...STRONGER
THAN AVERAGE NORTH-NORTHEAST FLOW WILL PERSIST OVERNIGHT AS WELL.

SOUTHEAST CALIFORNIA/SOUTHWEST ARIZONA INCLUDING KIPL AND KBLH...
WINDY CONDITIONS WILL DEVELOP DOWN THE CO RIVER VALLEY THIS MORNING.
NORTHERLY WINDS WILL GUST TO 25 AT KIPL BUT WILL BE EVEN STRONGER AT
KBLH WITH GUSTS POTENTIALLY AS HIGH 30 TO 35 KT. THERE IS ALSO THE
POSSIBILITY OF BLOWING DUST...WHICH MAY TEMPORARILY REDUCE
VSBYS...BEFORE CONDITIONS IMPROVE THIS EVENING.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
THURSDAY THROUGH MONDAY...
WIND SPEEDS WILL BEGIN TO DECREASE ON THURSDAY...HOWEVER LOCALIZED
STRONGER NORTHERLY GUSTS WILL STILL PREVAIL FOR MUCH OF THE DAY.
MUCH WEAKER AND MORE TYPICAL DIURNALLY FORCED WINDS CAN BE EXPECTED
THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK. HOWEVER DESPITE THE
WEAKER WINDS...TEMPERATURES WILL INCREASE TO ABOVE NORMAL LEVELS
WITH MANY LOWER ELEVATION LOCATIONS APPROACHING (OR POSSIBLY LOCALLY
EXCEEDING) THE 100 DEGREE MARK AS AFTERNOON MINIMUM HUMIDITY LEVELS
FALL WELL INTO THE SINGLE DIGITS (IN SOME CASES BELOW 5 PERCENT).
OVERNIGHT RECOVERY WILL ONLY BE POOR TO FAIR THROUGHOUT THE ENTIRE
PERIOD.
