AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
325 AM PDT MON APR 16 2007

.SYNOPSIS...A COLD UPPER LEVEL LOW OVER NORTHWEST ARIZONA WILL
SLOWLY MOVE EAST TODAY...BRINGING SCATTERED RAIN AND SNOW
SHOWERS AND UNSEASONABLY CHILLY TEMPERATURES TO THE AREA. THE LOW
WILL FINALLY MOVE AWAY MONDAY NIGHT...WITH RAIN CHANCES ENDING AND
WARMER TEMPERATURES EXPECTED ON TUESDAY. ANOTHER STORM WILL ROLL
INTO THE PACIFIC NORTHWEST ON TUESDAY...BRINGING A CHANCE OF HIGH
WINDS TO THE SOUTHERN SIERRA TUESDAY AFTERNOON AND OVER MUCH OF THE
MOJAVE DESERT AND SOUTHERN GREAT BASIN TUESDAY NIGHT AND WEDNESDAY.
FINALLY...ANOTHER LOW WILL IMPACT THE AREA LATE IN THE WEEK.
&&

.SHORT TERM...FORECAST AREA IN FOR A ROLLER COASTER RIDE THIS WEEK
AS PROGRESSIVE PATTERN WILL BE IMPACTING THE WEST COAST. UPPER LOW
OVER NORTHWEST ARIZONA EARLY THIS MORNING WITH BANDS OF SHOWERS
MOVING FROM NORTH-SOUTH ON BACKSIDE OF LOW. RADAR/SURFACE
OBSERVATIONS INDICATE MAIN BAND PRESENTLY EXTENDS FROM
DAGGETT-INDIAN SPRINGS-CALIENTE. INFRARED IMAGERY SHOWS CLOUD TOPS
HAVE BEEN WARMING SO EXPECT AREA WILL CONTINUE TO WEAKEN AND
DISSIPATE OVER THE NEXT 6 HOURS. ALLS QUITE OVER MOHAVE COUNTY BUT
DUE TO PROXIMITY OF UPPER LOW AND WITH SOME HEATING CLOUDS WILL
BUBBLE UP BY AFTERNOON. SHOWERS WILL END EARLY THIS EVENING OVER
NORTHWEST ARIZONA AS UPPER LOW ACCELERATES EAST AND SHORTWAVE RIDGE
MOVES INLAND ACROSS NEVADA AND CALIFORNIA. MODELS LOOK A TAD SLOWER
AND DEEPER WITH NEXT TROUGH MOVING INTO THE GREAT BASIN TUESDAY
NIGHT AND WEDNESDAY. THIS TROUGH WILL BE MORE OF A WIND PRODUCER
THAN PRECIPITATION MAKER. AS TROUGH MOVES INTO NORTHERN CALIFORNIA
TUESDAY AFTERNOON STRONG WINDS WILL BE PERPENDICULAR TO THE SIERRA
WHILE OTHER PARAMETERS LOOK FAVORABLE FOR A DOWNSLOPE WIND EVENT.
PERIOD FOR STRONG WINDS LOOKS TO BE BETWEEN 2 PM TUESDAY AND 6 AM
WEDNESDAY SO WILL ISSUE A HIGH WIND WATCH. STRONG BELT OF WINDS SAGS
SOUTH ACROSS SAN BERNARDINO...CLARK AND MOHAVE COUNTIES LATE TUESDAY
NIGHT THROUGH WEDNESDAY. TEMPERATURES WILL REMAIN BELOW NORMAL TODAY
THEN WARM ABOUT 10 DEGREES TUESDAY BEFORE COOLING
WEDNESDAY.

.LONG TERM...ACTIVE PATTERN SEEN CONTINUING FOR THE NEXT WEEK AS A
SERIES OF LOW PRESSURE SYSTEMS MOVE THROUGH THE WESTERN STATES. AS
WITH NEARLY EVERY LOW PRESSURE SYSTEM THIS WINTER/SPRING...
PRECIPITATION LOOKS TO BE MINIMAL FOR THE CWA AND MAIN EFFECTS WILL
BE WINDS. BEST DAY LOOKS TO BE THURSDAY AS THE REGION IS BETWEEN
SYSTEMS AND A FLAT RIDGE OVER THE AREA. THIS WOULD LEAD TO FAIRLY
LIGHT WINDS AND NEAR NORMAL TEMPERATURES. THE NEXT IN THE SERIES OF
LOW PRESSURE SYSTEMS WILL MOVE INTO THE PACIFIC NORTHWEST THURSDAY
NIGHT AND DROP INTO NORTHERN CA FRIDAY AFTERNOON. THIS WILL INCREASE
THE WINDS OVER THE CWA AND EXPECT MOST AREAS TO EXPERIENCE BREEZY TO
WINDY CONDITIONS FRIDAY AFTERNOON AND EVENING. THE LOW IS FORECAST
TO TRACK EAST ACROSS NORTHERN NEVADA AND BRING SLIGHT CHANCES OF
PRECIPITATION TO THE NORTHERN CWA WHILE THE SOUTH REMAIN DRY. THIS
IS A CHANGE FROM PREVIOUS RUNS WHICH HAD THE LOW TAKING A MORE
SOUTHERLY TRACK. THIS LOW WILL MOVE INTO UTAH SATURDAY AND LEAVE THE
AREA UNDER A NORTHWEST FLOW THROUGH THE REMAINDER OF THE EXTENDED.
THIS WILL LEAVE THE CWA WITH DRY CONDITIONS AND SLIGHTLY BELOW
NORMAL TEMPERATURES.
&&

.FIRE WEATHER...STRONG TROUGH MOVING INTO THE GREAT BASIN LATE
TUESDAY AND WEDNESDAY WILL PRODUCE A PERIOD OF STRONG AND GUSTY
WINDS. WINDS SPEEDS AND RELATIVE HUMIDITY VALUES LOOK MARGINAL
TUESDAY AFTERNOON IN ESMERALDA AND INYO COUNTIES. IT LOOKS MORE
FAVORABLE THAT RED FLAG CONDITIONS COULD BE WEDNESDAY ACROSS SAN
BERNARDINO...CLARK AND MOHAVE COUNTIES WITH SINGLE DIGIT RELATIVE
HUMIDITIES.
&&

.AVIATION...FOR KLAS: NORTHWEST TO NORTH WINDS WILL REMAIN ACROSS
THE VALLEY THROUGH 18Z AS LOW PRESSURE SLOWLY TRACKS SOUTHEAST AWAY
FROM THE AREA. WINDS ARE EXPECTED TO REMAIN AROUND 10-15 KTS BEFORE
DIMINISHING. ISOLATED SHOWERS WILL ALSO TRACK THROUGH THE
VALLEY...BUT SHOULD GENERALLY REMAIN LIGHT. CIGS MAY DROP AS LOW AS
6 KFT...BUT WILL GENERALLY REMAIN AROUND 7 KFT.

THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA: MOSTLY CLOUDY SKIES WITH SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS WILL PERSIST THROUGHOUT THE REST OF TONIGHT AND EARLY
MORNING BEFORE BEGINNING TO IMPROVE FROM WEST TO EAST BY 15Z. CIGS
WILL GENERALLY BE AROUND 10 KFT EXCEPT IN SHOWERS/TSTMS WHERE CIGS
AS LOW AS 5 KFT CAN BE EXPECTED.
&&

.VEF WATCHES/WARNINGS/ADVISORIES...
.NV...NONE.
.AZ...NONE.
.CA...HIGH WIND WATCH FROM 2 PM TUESDAY THROUGH 6 AM WEDNESDAY
      FOR ZONES 519 AND 520.
