AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
305 PM PDT SAT APR 23 2005

.SYNOPSIS...THERE WILL BE RAIN SHOWERS ALONG WITH A FEW
THUNDERSTORMS TONIGHT AS AN AREA OF LOW PRESSURE QUICKLY MOVES
ACROSS SOUTHERN CALIFORNIA TONIGHT AND INTO CENTRAL ARIZONA EARLY
SUNDAY MORNING. MOISTURE WILL LINGER ACROSS THE AREA WITH A CHANCE
OF SHOWERS CONTINUING MAINLY NORTH AND EAST OF LAS VEGAS SUNDAY. A
WEAK AREA OF HIGH PRESSURE WILL BE WARMER TEMPERATURES AND DRIER
WEATHER TO THE SOUTHERN GREAT BASIN AND MOJAVE DESERT MONDAY AND
TUESDAY.
&&

.SHORT TERM...RIGHT ON SCHEDULE...SHOWERS AND A THUNDERSTORMS BEGAN
DEVELOPING SHORTLY AFTER 1 PM. STRONG TIGHTLY WOUND-UP LITTLE
SHORTWAVE...WHICH WAS UNDER INITIALIZED BY ALL MODELS...STILL SOME
300 MILES SOUTHWEST OF SAN DIEGO. MOIST SOUTHERLY FLOW AHEAD OF
SYSTEM HAS INCREASED SURFACE DEWPOINTS SOME 15-25 DEGREES ACROSS
NORTHWEST ARIZONA AND SOUTHERN NEVADA COMPARED TO 24 HOURS AGO.
MOISTURE INCREASE ALSO MONITORED ON GOES PRECIPITABLE WATER IMAGERY
WITH VALUES BETWEEN .50-1.00 INCH AS FAR NORTH AS SOUTHERN NEVADA.
GFS HAS STAYED CONSISTENT AND WAS MODEL OF CHOICE TODAY. SHORTWAVE
WILL BE NEAR YUMA BY 06Z THIS EVENING AND OVER CENTRAL ARIZONA EARLY
SUNDAY MORNING. SHOWERS AND THUNDERSTORMS WILL EXPAND IN COVERAGE
THE REST OF THIS AFTERNOON AND EVENING AS ATMOSPHERE CONTINUES TO
DESTABILIZE AS COLD AIR ALOFT AND UPWARD FORCING SPREADS OVER THE
FORECAST AREA. BEST CHANCES OF RAIN AND THUNDERSTORMS WILL BE ACROSS
EASTERN CALIFORNIA...SOUTHEAST NEVADA UNTIL MIDNIGHT AND ACROSS
NORTHWEST ARIZONA ALL NIGHT. DID NOT MAKE MUCH CHANGE TO POPS FOR
THE SOUTHERN SIERRA OR ESMERALDA COUNTY BUT WITH SOUTHERN TRAJECTORY
OF SYSTEM THEY MAY MISS MOST OF THE ACTION. CELLS ARE MOVING QUICKLY
TO THE NORTH BUT STRONGER CELLS COULD PRODUCE BETWEEN A QUARTER AND
A HALF AN INCH OF RAINFALL. ON SUNDAY AREA STAYS UNDER WEAK...COOL
CYCLONIC FLOW. ENOUGH MOISTURE REMAINS THAT BY AFTERNOON INSTABILITY
SHOWERS WILL ERUPT ESPECIALLY NORTH AND EAST OF LAS VEGAS. WEAK
RIDGE BUILDS ACROSS THE AREA SUNDAY NIGHT THROUGH MONDAY NIGHT.
STILL LEFT A SLIGHT CHANCE OF SHOWERS IN MONDAY AFTERNOON OVER THE
HIGHER TERRAIN OF LINCOLN/NORTHERN MOHAVE COUNTIES DUE TO LINGERING
MOISTURE AND WEAK INSTABILITY.
&&

.LONG TERM...RIDGING OVER THE AREA TUESDAY AND WEDNESDAY WILL GIVE A
SLIGHT WARM UP FOR THE AREA BEFORE THE NEXT STRONG SYSTEM PUSHES
THROUGH ON FRIDAY. MODELS IN FAIR AGREEMENT WITH DIFFERENCES IN
TIMING OF WHEN TROUGH/LOW MOVES THROUGH. WILL NOT SWEAT THE SMALL
DETAILS THIS FAR OUT AND WENT WITH A BROAD BRUSH CONSENSUS FORECAST.
DID UP POPS A BIT TO 40 PERCENT FOR ALL DAY FRIDAY. IF MODELS
CONTINUE ON TRACK TOMORROW FOR FRIDAY WILL RAISE THIS HIGHER.
OTHERWISE DID NOT CHANGE MUCH TO ON GOING FORECAST.
&&

.AVIATION...STRONG LOW OFF THE SOUTHERN CALIFORNIA COAST WILL BRING
WIDE SPREAD PRECIPITATION TO THE AREA THIS AFTERNOON AND TONIGHT.
THERE IS A CHANCE KLAS COULD EXPERIENCE A THUNDERSTORM AS WELL. THE
MOSTLY LIKELY AREAS TO EXPERIENCE THUNDERSTORMS WILL BE OVER THE
MOUNTAIN AREAS OF THE PEACH SPRINGS AND MORMON MESA
APPROACHES...THOUGH THE DAGGETT APPROACH COULD HAVE THEM AS WELL
WITH LESSER COVERAGE THAN THE OTHER TWO CORRIDORS. ASIDE FROM THE
SHEEP RANGE THE BEATTY CORRIDOR WILL NOT LIKELY BE AFFECTED BY
THUNDER.
