AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
253 PM PDT WED JUN 3 2009

.SYNOPSIS...A DISTURBANCE AHEAD OF A PACIFIC LOW PRESSURE SYSTEM OFF
THE CENTRAL CALIFORNIA COAST WILL MOVE ACROSS THE AREA TONIGHT. THIS
WILL BRING ISOLATED TO SCATTERED THUNDERSTORMS TO THE REGION
FOLLOWED BY DRIER AND LOCALLY BREEZY CONDITIONS THURSDAY. THE
PACIFIC LOW PRESSURE SYSTEM WILL MOVE INLAND FRIDAY AND SATURDAY
BRINGING GUSTY WINDS AND A COOLING TREND ALONG WITH A CHANCE OF
THUNDERSTORMS ACROSS THE SOUTHERN GREAT BASIN. TEMPERATURES ARE
EXPECTED TO BE SEVERAL DEGREES BELOW NORMAL FRIDAY THROUGH SUNDAY.
&&

.SHORT TERM...BAND OF SHOWERS ACROSS SAN BERNARDINO AND INYO COUNTY
OUT AHEAD OF THE CLOSED LOW OFF THE COAST WILL PROGRESS SLOWLY
EASTWARD TONIGHT ACROSS SOUTHEAST CALIFORNIA AND INTO SOUTHERN
NEVADA. RAINFALL HAS BEEN LIGHT WITH THIS BAND AND MAINLY TRACE
AMOUNTS HAVE BEEN FALLING...AT LEAST WHERE RAIN GAUGES ARE LOCATED.
HAVE NOT SEEN ANY LIGHTNING IN OUR CWA LATELY BUT POTENTIAL STILL
EXISTS. THERE HAS BEEN PLENTY OF LIGHTNING JUST SOUTH AND JUST WEST
OF OUR CWA. THIS MOISTURE BAND WILL ROTATE INTO THE FAR EASTERN
PORTION OF THE FORECAST AREA EARLY THURSDAY WITH A DRY SLOT PUSHING
INTO MOST OF THE FORECAST AREA. LEFT A SLIGHT CHANCE OF
THUNDERSTORMS OVER NORTHERN MOHAVE COUNTY FOR THURSDAY WITH A CHANCE
OF THUNDERSTORMS STILL OVER THE SIERRA...CLOSER TO THE APPROACHING
CLOSED LOW. A STRONG SHORTWAVE WILL ROTATE AROUND THE BASE OF THE
LOW AND INTO THE FORECAST AREA THURSDAY NIGHT. HOWEVER...DRY AIR IS
STILL INDICATED BY THE MODELS OVER MOST OF THE FORECAST AREA. THERE
SHOULD BE ENOUGH FORCING SOMEWHERE FROM THIS FEATURE TO OVERCOME A
LACK OF MOISTURE. RIGHT NOW IT LOOKS LIKE THAT SOMEWHERE WILL BE
ACROSS MAINLY LINCOLN COUNTY AND INTO CENTRAL NYE COUNTY WHERE I
WENT WITH JUST A SLIGHT CHANCE OF THUNDERSTORMS. ALSO KEPT A SLIGHT
CHANCE OF THUNDERSTORMS IN THE SIERRA DUE TO PROXIMITY TO THE LOW.
THE LOW WILL MOVE INLAND ON FRIDAY BRINGING INCREASED INSTABILITY TO
THE NORTHWEST THIRD OF THE FORECAST AREA. LOOKS LIKE THE REMAINDER
OF THE FORECAST AREA WILL REMAIN DRY AND STABLE BUT BREEZY.
THUNDERSTORM CHANCES WILL SPREAD SOUTHEAST ACROSS ROUGHLY THE
NORTHERN HALF OF THE FORECAST AREA FOR SATURDAY AS THE LOW WEAKENS
AND MOVES OVER NEVADA. A COOLING TREND IS EXPECTED THROUGH THE SHORT
TERM AS THE LOW GRADUALLY MOVES IN WITH HIGH TEMPERATURES NEARLY 10
DEGREES BELOW NORMAL BY SATURDAY.

.LONG TERM...FOR THE PERIOD BEGINNING SUNDAY MORNING...VERY LITTLE
CHANGE WAS MADE TODAY AS MODELS CONTINUE TO SHOW THE AREA UNDER AN
UNSETTLED PATTERN THROUGH MOST OF THE EXTENDED. AS LOW PRESSURE
EXITS TO THE EAST SUNDAY MORNING...THERE IS INDICATION OF YET
ANOTHER LOW GETTING CUTTING OFF OFF THE CALIFORNIA COAST...WHICH
PASSES OVER TUESDAY AFTERNOON...FOLLOWED BY ANOTHER CUT OFF LOW
FORMING TOWARDS THE END OF NEXT WEEK. REGARDING TIMING AND
TRAJECTORY...THERE IS VERY LITTLE AGREEMENT AMONG GUIDANCE...AND
HAVE LEFT THE CURRENT FORECAST FOR NEAR NORMAL TEMPS AND SLIGHTLY
ABOVE AVERAGE PRECIP UNCHANGED...WITH LOWER THAN AVERAGE CONFIDENCE
IN THE EXTENDED.
&&

.AVIATION...FOR MCCARRAN...SOUTHWEST FLOW AHEAD OF A LOW PRESSURE
SYSTEM SPINNING OFF OF THE CALIFORNIA COAST WILL CONTINUE TO PULL
MID LEVEL MOISTURE OVER THE AREA THROUGH THE EVENING AND INTO THE
NIGHT. THE MAIN RESULT WILL BE INCREASED CLOUDS...WITH CIGS AROUND
10KFT. AS THIS AREA OF LOW PRESSURE DRIFTS SLIGHTLY EASTWARD BY
THIS EVENING...THERE WILL BE A CHANCE FOR SHOWERS AND CIGS AROUND
8KFT AS MAIN BAND OF PRECIP SHIFTS EAST. WESTERLY WINDS MAY ALSO BE
ENHANCED AT TIME THROUGH THE EVENING THANKS TO THE EXPECTED PRECIP
WEST OF THE AREA.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SHOWERS WITH ISOLATED EMBEDDED THUNDERSTORMS WILL
PERSIST THROUGH THE MAJORITY OF THE NIGHT AS LOW PRESSURE OFF THE
CALIFORNIA COAST CONTINUES TO FEED MOISTURE ACROSS THE AREA. THE
BEST CHANCE FOR SHOWERS/ISOLATED EMBEDDED THUNDERSTORMS THE REST OF
THE AFTERNOON WILL BE ACROSS SOUTHERN CALIFORNIA AND WEST OF CLARK
COUNTY IN NEVADA....BUT THIS LINE WILL SLOWLY SLIDE FARTHER EAT
THROUGH THE NIGHT.
&&

.FIRE WEATHER...INCREASING SOUTHWEST FLOW IS EXPECTED ACROSS
NORTHWEST ARIZONA THURSDAY THROUGH FRIDAY. WIND GUSTS OVER 35 MPH
ARE EXPECTED THURSDAY AFTERNOON AND AGAIN FOR MUCH OF THE DAY FRIDAY
OVER THE HIGHER TERRAIN OF MOHAVE COUNTY. RELATIVE HUMIDITY VALUES
DURING THE DAY WILL LIKELY FALL BELOW 15 PERCENT OVER MUCH OF THE
AREA SO A RED FLAG WARNING HAS BEEN ISSUED FOR THURSDAY AFTERNOON
THROUGH FRIDAY AFTERNOON.
&&
