AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
247 PM PDT SUN OCT 17 2010

.SYNOPSIS...SKIES WILL BE PARTLY TO MOSTLY CLOUDY THROUGH THE MIDDLE
OF THE WEEK WITH A POSSIBILITY OF RAIN SHOWERS AND THUNDERSTORMS
OVER MUCH OF THE AREA. SNOW SHOWERS WILL BE CONFINED TO THE HIGHEST
ELEVATIONS OF THE SIERRA AND SPRING MOUNTAINS WHERE ONLY A FEW
INCHES OF ACCUMULATION ARE EXPECTED. TEMPERATURES WILL BE NEAR
NORMAL THROUGH TUESDAY BEFORE COOLING TO BELOW NORMAL WEDNESDAY.
LOOKING AHEAD...ANOTHER STORM SYSTEM IS POSSIBLE FOR NEXT WEEKEND.
&&

.SHORT TERM...THE LOW PRESSURE SYSTEM THAT HAS BEEN ANTICIPATED FOR
SEVERAL DAYS IS COMING TOGETHER NICELY AND IS LOOKING RATHER
IMPRESSIVE ON SATELLITE. RADAR AND LIGHTNING DETECTION INDICATES
THAT SCATTERED SHOWERS AND THUNDERSTORMS HAVE ALREADY FORMED OVER
PORTIONS OF MOHAVE...CLARK...LINCOLN AND CENTRAL NYE COUNTIES THIS
AFTERNOON...IN AN AREA THAT LIES IN THE DIFFLUENT REGION OF AN 85 KT
JET THAT IS ASSOCIATED WITH THE LOW. BASED ON WATER VAPOR IMAGERY...
THE CENTER OF THE LOW APPEARED TO BE LOCATED ABOUT 125 MILES WEST OF
SAN FRANCISCO AND IS PROGGED TO SLIDE SOUTH TO NEAR POINT CONCEPTION
AROUND MID DAY MONDAY. IT CONTINUES TO DIG SOUTHWARD MONDAY NIGHT
AND FINALLY BOTTOMING OUT AROUND MID DAY TUESDAY NEAR THE WEST COAST
OF NORTHERN BAJA. FROM THERE...IT MOVES ACROSS NORTHERN BAJA AND
BEGINS TO LIFT TO THE NORTHEAST LATE TUESDAY INTO EARLY WEDNESDAY
BRINGING IT CLOSER TO THE FORECAST AREA ONCE AGAIN. TIMING AND
ACTUAL TRACK ARE SUBJECT TO CHANGE.

SINCE THE LOW STAYS WEST AND SOUTH OF THE AREA...SOUTHERLY FLOW
SHOULD KEEP SNOW LEVELS NEAR THE HIGHEST ELEVATIONS ABOVE 9 OR 10000
FEET THROUGH AT LEAST THE SHORT TERM. THEREFORE...NO WINTER WEATHER
PRODUCTS ARE ANTICIPATED AS THIS STORM IS EXPECTED TO BE MAINLY A
RAIN MAKER. RAIN AMOUNTS IN GENERAL COULD REACH .50 INCHES TO AN
INCH THROUGH WEDNESDAY MORNING WITH LOCALIZED HIGHER AMOUNTS.
HOWEVER...MODEL FORECASTS OF THE LOCATIONS FOR THE HEAVIEST RAIN
AMOUNTS HAS VARIED FROM RUN TO RUN AND WILL BE HARD TO PIN DOWN. NO
SIGNIFICANT WIND IS EXPECTED THROUGH THE SHORT TERM BUT ANYTIME
THUNDERSTORMS FORM THERE IS A POTENTIAL FOR BRIEF...STRONG WIND
GUSTS. ABUNDANT MID AND HIGH LEVEL MOISTURE WILL KEEP SKIES MOSTLY
CLOUDY OVER THE NEXT COUPLE OF DAYS ALTHOUGH THERE COULD BE BREAKS
IN THE SKY COVER AT TIMES. THE SOUTHERLY FLOW...AMOUNT OF CLOUD
COVER AND SHOWER ACTIVITY WILL ALL HAVE AN IMPACT ON THE TEMPERATURE
FORECAST. OFFICIALLY...DAYTIME HIGHS SHOULD BE RIGHT AROUND NORMAL
THROUGH TUESDAY.
&&

.LONG TERM...MODEL SOLUTIONS BEGIN TO DEVIATE WEDNESDAY AND BEYOND.
THE ECMWF AND GEM BRING ANOTHER STRONG LOW TO THE WEST COAST NEARLY
ON THE TAIL END OF THE CURRENT ONE LATE IN THE WEEK WITH LITTLE TO
NO BREAK IN SHOWER ACTIVITY BETWEEN SYSTEMS. THEIR RESPECTIVE
SOLUTIONS DEVIATE SIGNIFICANTLY AS THE LOW REACHES THE COAST
HOWEVER. THE GFS BRINGS A WEAKER NEGATIVELY TILTED OPEN WAVE ACROSS
THE AREA LATE FRIDAY AND THIS SOLUTION MERGES WITH THE EC SOLUTION
NEXT WEEKEND. TEMPERATURES LOOK LIKE THEY WILL BE BELOW NORMAL FROM
WEDNESDAY ON. MORE DETAILS TO COME.
&&

.AVIATION...FOR MCCARRAN...IN THE SHORT TERM...WINDS WILL BE
INFLUENCED BY LOCAL THUNDERSTORM ACTIVITY AND ASSOCIATED OUTFLOW.
THUNDERSTORMS WILL IMPACT ALL APPROACHES INTO MCCARRAN THROUGH EARLY
EVENING WITH SHOWERS AND THUNDERSTORMS POSSIBLE OVERNIGHT AND INTO
MONDAY. CIGS FROM 10-12K FT INITIALLY LOWERING THROUGH THE NIGHT TO
AROUND 8K FT. ALSO...LOWER CIGS IN RAIN AREAS. THIS SYSTEM WILL STAY
CLOSE ENOUGH TO SOUTHERN NEVADA TO CONTINUE THE POSSIBILITY OF SHRA
OR TSRA AT OR NEAR THE AIRPORT AND IN THE APPROACH CORRIDORS THROUGH
THURSDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS WILL GENERALLY BE UNDER 10 KTS AND FROM THE SOUTH
BUT ERRATIC AND GUSTY IN AND NEAR SHOWERS AND THUNDERSTORMS. BKN-OVC
CIGS AOA 10K FEET BUT LOWER IN SHRA OR TSRA AREAS. MOUNTAIN
OBSCURATIONS ARE EXPECTED AT TIMES ESPECIALLY IN THE EASTERN SIERRA
WHERE CIGS AROUND 5K FT ARE POSSIBLE THIS EVENING AND MONDAY. SHRA
AND TSRA WILL BE POSSIBLE ACROSS THE AREA THROUGH THURSDAY.

.DAY ONE...TODAY AND TONIGHT

A STRENGTHENING LOW PRESSURE SYSTEM WILL MOVE TO THE CENTRAL
CALIFORNIA COAST TODAY BRINGING A CHANCE OF SHOWERS AND

IS POSSIBLE AT THE HIGHEST ELEVATIONS. SOME STORMS COULD PRODUCE
BRIEF HEAVY RAIN AND GUSTY WINDS.

THE LOW PRESSURE SYSTEM WILL LINGER JUST TO OUR SOUTH KEEPING A

FOR LOCALLY MODERATE TO HEAVY RAIN MONDAY THROUGH WEDNESDAY BUT
IT IS DIFFICULT AT THIS TIME TO PREDICT EXACTLY WHERE THAT MAY
OCCUR. THE LOW WILL FINALLY MOVE EAST OF THE AREA BY THE END OF
THE WEEK WITH DRIER CONDITIONS DEVELOPING.
