.PREV DISCUSSION...
440 PM PDT SAT MAY 22 2010

.SHORT TERM...MODELS CONTINUE TO BE IN PRETTY GOOD AGREEMENT WITH
THE OVERALL PATTERN THROUGH TUESDAY. THE STRONG UPPER LOW THAT HAS
BEEN RESPONSIBLE FOR GUSTY WINDS ACROSS THE MOJAVE DESERT TODAY WILL
MOVE INTO CENTRAL CALIFORNIA TONIGHT AND INTO SOUTHERN NEVADA
SUNDAY. KEPT THE WIND ADVISORY GOING FOR WESTERN SAN BERNARDINO
COUNTY IN CALIFORNIA WITH GUSTS JUST OVER 40 MPH BEING OBSERVED AT 3
PM. SHOWERS ASSOCIATED WITH THE LOW WILL DEVELOP ACROSS THE
NORTHWEST PORTION OF THE FORECAST AREA TONIGHT AND ACROSS ALL BUT
THE FAR SOUTHERN PORTION OF THE AREA SUNDAY AS THE LOW MOVES
OVERHEAD. DUE TO LIMITED MOISTURE...DO NOT EXPECT ANY SIGNIFICANT
PRECIPITATION BUT A FEW HIGHER PEAKS COULD GET AN INCH OR TWO OF
SNOW WITH SNOW LEVELS LOWERING TO NEAR 5000 FEET. WITH THE COLD AIR
ALOFT MOVING OVER THE AIR MASS WILL BECOME SOMEWHAT UNSTABLE AND
ISOLATED THUNDERSTORMS ARE A POSSIBILITY...MAINLY NORTH OF LAS
VEGAS. LATEST MOS GUIDANCE CAME IN EVEN COOLER THAN PREVIOUS RUNS
AND HIGH TEMPERATURES SUNDAY WILL BE 20-25 DEGREES BELOW NORMAL.
GUSTY WINDS ARE STILL EXPECTED ON THE SOUTH/SOUTHEAST EDGE OF THE
LOW SUCH AS THE BARSTOW/DAGGETT AND KINGMAN AREAS BUT WINDS SHOULD
REMAIN JUST BELOW ADVISORY CRITERIA.

THE LOW WILL MOVE FAIRLY QUICKLY TO THE NORTHEAST SUNDAY NIGHT WITH
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS LINGERING MAINLY IN THE
EVENING HOURS. A DRIER AND WEAKER WESTERLY FLOW WILL DEVELOP MONDAY
WITH TEMPERATURES STARTING TO WARM A LITTLE. YET ANOTHER SPRING
STORM WILL APPROACH THE COAST TUESDAY WITH A DRY SOUTHWEST FLOW OVER
THE MOJAVE DESERT AND SOUTHERN GREAT BASIN. ALTHOUGH TEMPERATURES
WILL CONTINUE TO WARM TUESDAY...HIGH TEMPERATURES WILL STILL BE
NEARLY 10 DEGREES BELOW NORMAL.

.LONG TERM...WEDNESDAY MORNING THROUGH SATURDAY...A STRONG RIDGE
OVER THE MISSISSIPPI VALLEY AT THE BEGINNING OF THE PERIOD WILL
RETROGRADE TOWARDS THE PLAINS STATES AND KEEPS A DEEP LOW AND TROUGH
ANCHORED OFF THE PACNW/BC COAST FOR A FEW DAYS. THIS WILL KEEP THE
AREA UNDER MODERATELY STRONG SOUTHWEST FLOW. THIS SHOULD MAKE FOR
BREEZY CONDITIONS OVER SOME AREAS OF THE CWA. FORECAST 700 MB WINDS
ARE IN THE 40-45 KNOT RANGE WEDNESDAY TO FRIDAY AND NOT STRONG
ENOUGH TO GET ABOVE THE BREEZY OR WINDY LEVEL. DESPITE GENERALLY
BEING A WARMING SOUTHWEST FLOW HEIGHTS WILL BE BELOW SEASONAL NORMS
AND HENCE EXPECT TEMPERATURES TO RISE BUT STILL BE BELOW NORMAL FOR
LATE MAY. PRECIPITATION CHANCES WILL BE CONFINED TO THE SIERRA AND
AREAS IN THE NORTHERN ZONES HIGH TERRAIN.

MODELS DO HAVE A DECENT CONSENSUS AND AGREE ON BRING THE SYSTEM
INLAND SATURDAY SLOWLY. FOR NOW EXPECT HIS TO BE A MOSTLY DRY EVENT
WITH A SMALL POSSIBILITY FOR PRECIPITATION IN THE NORTHERN ZONES.
TEMPERATURES SHOULD ALSO TAKE A DROP NEXT WEEKEND AS WELL WITH THE
TROUGH PASSAGE.

.FIRE WEATHER...LOW HUMIDITIES WITH WINDS GUSTING OVER 35 MPH WERE
FAIRLY WIDESPREAD THIS AFTERNOON ACROSS THE RED FLAG WARNING AREA.
PORTIONS OF CLARK COUNTY WERE MARGINAL ON THE WIND GUSTS BUT OVERALL
THE WARNING STILL LOOKS GOOD THROUGH THIS EVENING. SUNDAY...SOME
AREAS WILL STILL BE GUSTING OVER 35 MPH...PARTICULARLY IN SAN
BERNARDINO AND MOHAVE COUNTIES BUT TEMPERATURES WILL BE QUITE COOL
AND RELATIVE HUMIDITY VALUES MOSTLY OVER 15 PERCENT THROUGHOUT THE
DAY.
