AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
905 PM PDT TUE JUN 2 2009

.SYNOPSIS...A PACIFIC LOW PRESSURE SYSTEM OFF THE CENTRAL CALIFORNIA
COAST WILL CONTINUE TO BRING DRY SOUTHWEST FLOW ACROSS SOUTHERN
CALIFORNIA AND SOUTHERN NEVADA TONIGHT AND INTO WEDNESDAY. AS THE
SYSTEM GRADUALLY MOVES INLAND...INCREASING SOUTHWEST WINDS WILL
DEVELOP ALONG WITH A COOLING TREND WHICH WILL DROP HIGH TEMPERATURES
SEVERAL DEGREES BELOW NORMAL BY THE END OF THE WEEK.
&&

.UPDATE...SATELLITE AND AREA RADARS SHOW THAT PRECIP HAS ENDED FOR
THE TIME BEING. RECENT CLOUD ENHANCEMENTS OVER INYO AND NYE COUNTIES
ARE LIKELY MOUNTAIN ENHANCED CLOUDS ASSOCIATED WITH INCOMING JET
STREAK. GUSTY SOUTH WINDS ARE PERSISTING IN THE OWENS VALLEY AND
OVER THE NEVADA TEST SITE...WHERE MODELS HAVE BEEN UNDERDOING WINDS
FOR A COUPLE OF DAYS. WILL UPDATE TO REMOVE PRECIP CHANCES TONIGHT
AND BUMP UP WINDS IN THE AFOREMENTIONED ZONES.
&&

.PREV DISCUSSION...
330 PM PDT TUE JUN 2 2009

.SHORT TERM...A LOW PRESSURE SYSTEM LOCATED OFF THE COAST OF CENTRAL
CALIFORNIA WILL CONTINUE TREK TOWARDS SHORE OVER THE NEXT FEW DAYS.
THE EFFECTS OF THIS SYSTEM HAVE BEGUN TO REACH OUR CWA AS AN AREA OF
DRY AIR HAS MOVED OVER THE REGION TODAY AND IS EXPECTED TO PERSIST
INTO TOMORROW...REDUCING THE CHANCE FOR DIURNAL AFTERNOON
THUNDERSTORMS TOMORROW. HOWEVER...OROGRAPHIC BASED CONVECTION ALONG
THE SIERRA CREST IS STILL A POSSIBILITY. LI PROGS CONCUR WITH THIS
OVER ALL SYNOPTIC SET UP AS ALL BUT THE THE SIERRA CREST ARE
REPRESENTED IN POSITIVE VALUES. SIMILAR CONDITIONS EXPECTED ON
THURSDAY. SOME MID TO UPPER LEVEL MOISTURE IS EXPECTED TO MOVE
THROUGH DURING THE DAY WEDNESDAY IN THE FORM OF HIGH CLOUDS. IN
ADDITION...GUSTY SOUTH WINDS ARE EXPECTED IN THE AFTERNOON ACROSS
THE NORTHERN ZONES. THE MAIN STORY FOR WINDS WILL BE FRIDAY
AFTERNOON AS THE CENTER OF THE LOW PRESSURE SYSTEM MAKES ITS WAY ON
SHORE OVER CENTRAL CALIFORNIA. BOTH THE ECMWF AND THE NAM12 BRING
100+ KNOT UPPER LEVEL JET LEADING THE LOW OVER SOUTHERN CALIFORNIA
THURSDAY AFTERNOON. THIS WILL RESULT IN GUSTY SOUTHWEST SURFACE
WINDS ACROSS THE FORECAST AREA...WITH THE STRONGEST WINDS ALONG THE
COLORADO RIVER VALLEY...LINCOLN AND MOHAVE COUNTIES. WILL KEEP AN
EYE ON THE NEXT FEW MODEL RUNS TO SEE IF THESE WILL MATERIALIZE INTO
ADVISORY LEVEL CONDITIONS. A DECREASING TEMPERATURE TREND IS
EXPECTED THROUGH THE END OF THE WEEK IN ASSOCIATION WITH THE
APPROACHING LOW.

.LONG TERM...LITTLE CHANGE WAS NEEDED THIS AFTERNOON TO INHERITED
GRIDS AS MODELS SHOW BETTER CONTINUITY WITH THE NEXT LOW PRESSURE
SYSTEM TO IMPACT THE REGION FRIDAY AND THROUGH THE WEEKEND. BREEZY
TO WINDY CONDITIONS ARE EXPECTED AREAWIDE ON FRIDAY AS LOW PRESSURE
APPROACHING FROM THE WEST TIGHTENS SURFACE GRADIENTS AND WINDS ALOFT
INCREASE. BY FRIDAY AFTERNOON DRY AND STABLE AIR WILL PERSIST OVER
THE MOJAVE DESERT...BUT THIS WILL NOT BE THE CASE FURTHER NORTH
WHERE GREATER MID-LEVEL MOISTURE WILL EXIST ACROSS THE NORTHWEST
PART OF THE CWFA AND INSTABILITY WILL BE BETTER DUE TO THE PROXIMITY
TO THE COLD POOL ALOFT ASSOCIATED WITH THE LOW. THE MAIN CONCERN ON
FRIDAY IS THE POTENTIAL FOR ORGANIZED CONVECTION ACROSS THESE
AREA...WITH 0-6KM BULK SHEAR VALUES APPROXIMATELY 50-60KTS FRIDAY
AFTERNOON COMBINED WITH NEGATIVE LIS. AS THE LOW APPROACHES AND
TEMPS ALOFT COOL...SNOW LEVELS WILL DROP TO AROUND 8500 FEET OVER
INYO COUNTY AND THE HIGHEST PEAKS OF THE SIERRA AND WHITE MOUNTAINS
COULD SEE A LITTLE SNOW FRIDAY AFTERNOON AND THROUGH THE NIGHT.
MODELS STILL INDICATE AN INITIAL PIECE OF ENERGY BREAKING OFF THE
PARENT LOW BY SATURDAY MORNING BEFORE THE MAIN AREA OF LOW PRESSURE
CROSSES AND EXITS THE REGION SUNDAY AFTERNOON AND EVENING. THIS WILL
KEEP AT LEAST A CHANCE FOR THUNDERSTORMS ACROSS NORTHERN ZONES
THROUGH THE WEEKEND AND TEMPS AT OR A FEW DEGREES BELOW NORMAL. HAVE
DECREASED TEMPERATURES SLIGHTLY AGAIN...LEANING TOWARDS RAW MODEL
GUIDANCE AS ANY BIAS CORRECTION WOULD LIKELY BE ON THE HIGH SIDE
GIVEN THE PATTERN CHANGE.

.AVIATION...FOR MCCARRAN...THERE WILL BE LITTLE CHANGE OVER THE
NEXT 24 HOURS AS WINDS REMAIN PRIMARILY OUT OF THE SOUTHWEST AND FEW
TO SCATTERED HIGH CLOUDS LINGER OVER THE LAS VEGAS VALLEY. WINDS ARE
EXPECT TO BE GUSTY AGAIN TOMORROW AFTERNOON...UP TO 20 KTS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...THERE WILL BE A SLIGHT CHANCE OF AFTERNOON
THUNDERSTORMS AGAIN OVER THE SOUTHERN SIERRA ON WEDNESDAY...BUT
OTHERWISE...NO SIGNIFICANT WEATHER IS EXPECTED ON WEDNESDAY AS DRY
STABLE AIR CONTINUES TO MOVE OVER THE AREA. BREEZY SOUTHWESTERLY
WINDS CAN BE EXPECTED AGAIN TOMORROW AFTERNOON.
