AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
940 AM PDT WED APR 5 2006

.SYNOPSIS...A COLD UPPER LEVEL LOW WILL MOVE THROUGH CENTRAL AND
SOUTHERN NEVADA TODAY...BRINGING SCATTERED THUNDERSTORMS TO MUCH OF
THE MOJAVE DESERT AND SOUTHERN GREAT BASIN. GUSTY WINDS WILL ALSO
CONTINUE THROUGH THE DAY. MOST AREAS WILL NOT SEE WINDS AS STRONG AS
WHAT OCCURRED TUESDAY AFTERNOON AND TUESDAY NIGHT. THE EXCEPTION
WILL BE THE DESERTS OF SAN BERNARDINO COUNTY...WHERE A WIND ADVISORY
IS IN EFFECT FROM NOON UNTIL 7 PM. THE UPPER LOW WILL MOVE AWAY
TONIGHT...AND THE WEATHER WILL BE DRY AND SEASONABLY WARM THURSDAY
AND FRIDAY.
&&

.UPDATE...CURRENT FORECAST LOOKS ON TRACK WITH NO CHANGES COMING.
WITH COLD CORE FORECAST TO MOVE OVER THE CWA THIS AFTERNOON AND
PLENTY OF SUNSHINE BEFORE THAT. I SEE NO REASON THAT THUNDERSTORMS
WONT POP AS WE BREAK THE CAP LATER THIS MORNING. WITH FREEZING
LEVELS SO LOW...SMALL HAIL MAY ACCOMPANY SOME OF THE LARGER STORMS.

&&

.PREV DISCUSSION...
522 AM PDT WED APR 5 2006

.UPDATE...WINDS HAVE REMAINED BELOW ADVISORY CRITERIA IN MOST PLACES
FOR A COUPLE OF HOURS AND PRESSURES HAVE RISEN RAPIDLY...DECREASING
THE GRADIENT IN THE ADVISORY AREA. SO...CANCELLED THIS MORNINGS WIND
ADVISORY AN HOUR EARLY. HOWEVER...ISSUED A NEW WIND ADVISORY FOR THE
SAN BERNARDINO COUNTY DESERTS FROM NOON UNTIL 7 PM TODAY...AS
WESTERLY WINDS SHOULD PICK UP AS THE UPPER LOW PASSES BY. WINDS WILL
BE ESPECIALLY STRONG WHERE TERRAIN CHANNELS THE WIND...SUCH AS THE
BARSTOW/DAGGETT AREA. ALSO ALLOWED SNOW ADVISORY FOR THE SIERRAS TO
EXPIRE ON SCHEDULE AT 5 AM. UPDATE ALREADY OUT.

.SHORT TERM...TOUGH NIGHT AT THE WFO. RAIN...THUNDERSTORMS...STRONG
WINDS...AND A DEAD RADAR. SATELLITE...SURROUNDING RADARS...AND
SURFACE OBS SUGGEST THAT PRECIP IS CONFINED WEST OF A LINE FROM
ESSEX...TO BOULDER CITY...TO SPRING VALLEY STATE PARK. THUNDERSTORMS
HAVE BEEN POPPING IN CLUSTERS. ONE CLUSTER OCCURRED ABOUT MIDNIGHT
NEAR BISHOP...OTHERS ABOUT THE SAME TIME OVER THE SPRING MOUNTAINS
AND NEAR CALIENTE...AND ANOTHER BETWEEN 2 AND 3 AM OVER LINCOLN
COUNTY. WATER VAPOR LOOP SHOWS MAIN UPPER LOW FINALLY MOVING INLAND
SO THUNDERSTORMS IN MOST AREAS TODAY WITH COLD POOL ALOFT LOOKS LIKE
A GOOD BET. WINDS HAVE BEEN PROBLEMATIC AS WELL. LOTS OF GUSTS
BETWEEN 40 AND 60 MPH HAVE BEEN REPORTED OVERNIGHT...WHICH FIT THE
WIND ADVISORY NICELY. WILL MAKE A LAST MINUTE CALL WHETHER OR NOT TO
EXTEND THE ADVISORY PAST 6 AM FOR NV/CA ZONES. WILL PROBABLY LET THE
SNOW ADVISORY FOR THE SIERRAS EXPIRE AT 5 AM. SNOW SHOWERS ARE STILL
EXPECTED TODAY...BUT AMOUNTS WILL PROBABLY AVERAGE LESS THAN
ADVISORY CRITERIA /WITH LOTS OF VARIABILITY DUE TO THE SHOWERY
NATURE/. THIS EVENT WILL BE OVER BY EARLY TOMORROW MORNING...WITH
QUIET WEATHER EXPECTED THURSDAY AND FRIDAY. ADDED SMALL POPS TO THE
HIGHER TERRAIN OF ESMERALDA AND INYO COUNTIES FRIDAY NIGHT WITH THE
NEXT SYSTEM MOVING IN.

.LONG TERM...LATEST MODEL RUNS DO NOT HOLD OUT MUCH HOPE FOR ENDING
THE UNSETTLED WEATHER PATTERN THAT HAS BEEN FOCUSING ON THE WESTERN
CONUS OVER THE PAST COUPLE OF WEEKS. THE LONG WAVE PATTERN CONTINUES
TO SUPPORT WEATHER SYSTEMS MOVING INTO THE AREA BRINGING UNSETTLED
CONDITIONS TO THE AREA ON AND OFF THROUGH THE EXTENDED. MODELS
DIFFER IN PLACEMENT AND TIMING OF INCOMING SYSTEMS BUT ARE GENERALLY
IN GOOD AGREEMENT WITH BRINGING OCCASIONALLY WET/WINDY WEATHER TO
THE AREA. HOWEVER...SATURDAY INTO EARLY SUNDAY SHOULD BE A
RELATIVELY QUIET/NICE PERIOD AS TEMPS WARM TO ABOVE NORMAL BOTH
DAYS. THE NEXT STORM SYSTEM IS SLATED TO REACH THE AREA LATE SUNDAY
AND CONTINUE INTO MONDAY FOLLOWED BY A BRIEF BREAK TUESDAY AND THEN
ANOTHER SYSTEM MID WEEK. TOO EARLY TO FOCUS ON PRECIP AMOUNTS JUST
YET BUT EACH SYSTEM COULD POTENTIALLY BRING SHOWER ACTIVITY TO THE
ENTIRE CWA. TEMPERATURES SLIDE BACK BELOW NORMAL MONDAY AND STAY
THERE AT LEAST THROUGH THE MIDDLE OF THE WEEK.

.AVIATION...MESSY CONDITIONS TODAY. COLD UPPER LOW MOVING OVERHEAD
WILL BRING UNSTABLE AIR AND SCATTERED THUNDERSTORMS. STRONG WINDS
THIS MORNING WILL SUBSIDE SOME DURING THE DAY BUT GUSTS WILL
CONTINUE ALL DAY IN MOST AREAS. CONDITIONS WILL IMPROVE OVERNIGHT
TONIGHT...AND THURSDAY WILL BE TRANQUIL. SEE TAFS FOR KLAS...
KVGT... KDRA... KBIH... KDAG...KEED.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

...SHOWERS AND THUNDERSTORMS EXPECTED TO REDEVELOP LATE THIS
MORNING AND AFTERNOON...

A COLD LOW PRESSURE SYSTEM CURRENTLY MOVING INTO SOUTHERN NEVADA
IS EXPECTED TO GENERATE ADDITIONAL SHOWERS AND THUNDERSTORMS
TODAY.

COLD TEMPERATURES ALOFT COMBINED WITH SOME MORNING SUNSHINE WILL
DESTABILIZE THE ATMOSPHERE ENOUGH TO BRING SCATTERED SHOWERS AND
THUNDERSTORMS TO MUCH OF THE SOUTHERN GREAT BASIN. THESE STORMS
WILL HAVE THE POTENTIAL TO PRODUCE SMALL HAIL AND SNOW LEVELS DOWN
TO 5000 FEET.
