AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1020 AM PDT SAT JUN 11 2005

.SYNOPSIS...A WEAK STORM SYSTEM MOVING ACROSS THE SOUTHERN GREAT
BASIN WILL PRODUCE ISOLATED THUNDERSTORMS OVER SOUTHERN NEVADA AND
NORTHWEST ARIZONA TODAY...BEFORE SHIFTING EAST TONIGHT. A WEAK HIGH
PRESSURE SYSTEM WILL THEN ALLOW FOR DRIER CONDITIONS WITH
TEMPERATURES WARMING TO NEAR NORMAL BY THE MIDDLE OF NEXT WEEK.
&&

.UPDATE...UPDATED MANY LOCATIONS FOR SLIGHTLY HIGHER TEMPS ACROSS
CLARK COUNTY...SAN BERNARDINO AND MOHAVE COUNTY THIS AFTERNOON. ALSO
BUMPED UP POPS FROM NORTHERN CLARK COUNTY INTO LINCOLN COUNTY AND
ALSO NORTHERN MOHAVE COUNTY FOR THE REST OF THE DAY. MAIN SHORTWAVE
EVIDENT ON WATER VAPOR JUST TO THE NORTH OF LINCOLN COUNTY IN
CENTRAL WHITE PINE COUNTY. SHOWERS AND THUNDERSTORMS HAVE PERSISTED
IN LINCOLN COUNTY SINCE EARLY THIS MORNING AND CONTINUE ACROSS THE
EASTERN HALF OF THE COUNTY CURRENTLY. RAINFALL AMOUNTS HAVE RANGED
FROM ONE QUARTER OF AN INCH TO THREE QUARTERS OF AN INCH. A STRONG
JET IS DIGGING INTO THE REGION FROM THE NORTHWEST AND WILL PASS
ACROSS SOUTHERN NEVADA LATE THIS AFTERNOON AND THIS EVENING. THIS
WILL PROVIDE ENHANCED DYNAMICS FOR ANY LINGERING MOISTURE TO PRODUCE
AFTERNOON CONVECTION...MAINLY IN CLARK...LINCOLN AND MOHAVE
COUNTIES. THIS AFTERNOON WILL BE A BIT OF A BATTLE BETWEEN THE
DYNAMICS AND THE INTRUDING DRY AIR THAT WILL ALSO BE TAKING PLACE
FROM WEST TO EAST. EASTERN LINCOLN...NORTHEAST CLARK AND NORTHERN
MOHAVE COUNTIES WILL BE THE FAVORED AREAS FOR AFTERNOON CONVECTION.
ALTHOUGH THE WINDOW FOR STRONG THUNDERSTORMS IS SMALL...20 TO
00Z...ANY THUNDERSTORM THAT DO DEVELOP THIS AFTERNOON WILL HAVE THE
POTENTIAL TO PRODUCE SMALL HAIL AND WIND GUSTS TO 60 MPH. NAM BUFR
CAPE VALUES ARE IN EXCESS OF 500 J PER KG WITH LIFTED INDICES
RANGING FROM MINUS 2 TO MINUS 5 ACROSS THE FAVORED AREAS.

.PREV DISCUSSION...NOCTURNAL CONVECTION CONTINUES OVER CENTRAL
NEVADA AS STRONG SHORTWAVE OVER NORTHERN CALIFORNIA SHIFTS TO THE
EAST. WATER VAPOR ALSO INDICATES STRONG JET STREAK BEGINNING TO COME
ONSHORE AND THIS SHOULD ADD TO DYNAMICS ALREADY IN PLACE OVER
CENTRAL NEVADA THIS MORNING. GFS SEEMS TO BE A LITTLE WEAK ON THE
INSTABILITY BUT NAM SEEMS TO HAVE A GOOD HANDLE ON IT SO TRENDED THE
FORECAST IN THAT DIRECTION FOR TODAY. SHORTWAVE FEATURE EXPECTED TO
CARVE OUT A WEAK TROUGH AS IT SLIDES SOUTHEAST INTO SOUTHERN CA AND
SOUTHERN NV THIS MORNING. GFS/NAM SHOWING ENOUGH AVAILABLE MOISTURE
OVER MOST OF SOUTHERN NEVADA AND NORTHWEST ARIZONA TO MENTION
ISOLATED TO SCATTERED THUNDER AS THIS SYSTEM MOVES THROUGH. ALTHOUGH
SURFACE DEWPOINT DEPRESSIONS ARE STILL PRETTY HIGH...PW SENSOR AT
MCCARRAN ALREADY SHOWING NEAR 0.85 INCHES. CONCERN FOR TODAY WILL BE
FIRE WEATHER AS SOME OF THESE THUNDERSTORMS WILL BE DRY AT LEAST
INITIALLY. NOT TOO WORRIED ABOUT LINCOLN COUNTY SINCE I BELIEVE
THERE IS ENOUGH AVAILABLE MOISTURE FOR THUNDERSTORMS TO BE
ACCOMPANIED BY RAIN...BUT PARTS OF CLARK...CENTRAL NYE...AND MOHAVE
COUNTIES COULD SEE SOME DRY LIGHTNING STRIKES. SHOWERS/THUNDER
SHOULD CONTINUE INTO THE EVENING HOURS BEFORE SHIFTING EAST WITH THE
TROUGH AXIS OVERNIGHT. WILL THEN SEE DRYING OVER THE AREA WITH
WARMER TEMPERATURES AS WEAK RIDGING BUILDS OVER THE AREA ON SUNDAY
AND MONDAY. BY MONDAY TEMPS SHOULD BE BACK UP TO NEAR NORMAL. &&

.LONG TERM...MODELS CONTINUE TO BE IN GOOD AGREEMENT WITH TREATMENT
OF DEVELOPING LOW OFF THE PACNW COAST INTO THE FIRST OF NEXT WEEK.
GFS REMAINS THE STRONG OF THE RUNS...WHILE CANADIAN WEAKER AND LOOKS
TO BE A LITTLE MORE PROGRESSIVE. TRENDING TOWARDS THE GFS...UPPER
LOW TO BE NEAR 48N/135W BY 12Z TUESDAY AND THEN SLOWLY SHIFT
SOUTHEAST BY 12Z FRIDAY WITH LOW OFF THE SOUTHERN OREGON COAST AT
THAT TIME. INCREASED SOUTHWEST FLOW ACROSS THE CWA AS LOW SHIFTS
SOUTHEAST WITH MAIN QUESTION BEING HOW FAR WILL THE SHORT WAVE
RIPPLES BRING THE PRECIPITATION DOWN. AT THIS POINT MODEL INDICATES
THAT MAIN ACTIVITY TO REMAIN OVER THE CENTRAL SIERRA WITH LITTLE
INTRUSION INTO THE SOUTHERN SIERRA AND FOR NOW WILL CONTINUE CURRENT
FORECAST TREND OF KEEPING AREA DRY. WILL NEED TO WATCH NEXT SEVERAL
RUNS HOWEVER AS MAY NEED TO KICK POPS UP LATER. SOUTHWEST FLOW AHEAD
OF THE SYSTEM TO ALLOW TEMPS TO BUMP UPWARDS DURING THE LONG TERM
WITH AFTERNOON READINGS BEING NEAR NORMAL TUESDAY/WEDNESDAY. AS
TROUGH DROPS SOUTH HOWEVER...HEIGHTS/THICKNESS DROPS AND A POSSIBLE
INCREASE IN CLOUD COVER WOULD LIKELY LOWER TEMPS A LITTLE BELOW
NORMAL. WILL ALSO PUSH BREEZY CONDITIONS IN OUR MOST FAVORITE AREAS
TOWARDS THE END OF THE PERIOD.
&&

.AVIATION...ISOLATED THUNDERSTORMS TO CONTINUE ACROSS THE BEATTY
CORRIDOR THROUGH THE EARLY MORNING HOURS THEN SHIFT SOUTH INTO
EXTREME SOUTHERN NEVADA AND NORTHWEST ARIZONA BY LATE
MORNING/AFTERNOON THUS EFFECTING BOTH MORMON MESA/PEACH SPRING
CORRIDORS. ALTHOUGH THUNDERSTORMS NOT EXPECTED AT KLAS TODAY...
POSSIBLE ACTIVITY OVER NEARBY MOUNTAINS AFTER 18Z MAY CAUSE SOME
ERRATIC WINDS AT TIMES DURING THE AFTERNOON AND EARLY EVENING HOURS.
