AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1005 PM PDT SAT MAR 21 2009
.SYNOPSIS...A STRONG PACIFIC STORM WILL MOVE INTO THE AREA TONIGHT
AND SUNDAY...RESULTING IN LOCAL WINDY CONDITIONS TONIGHT AND THEN
STRONG AND GUSTY WINDS ON SUNDAY. SCATTERED TO NUMEROUS RAIN AND
SNOW SHOWERS AND MUCH COOLER TEMPERATURES WILL ALSO BE SEEN ON
SUNDAY. GUSTY NORTHWEST WINDS AND DRIER WEATHER WILL THEN DEVELOP
SUNDAY NIGHT AND MONDAY AS THE SYSTEM MOVES EAST.
&&
.UPDATE...NAM...MET GUIDANCE...AND OUR LOCAL MESOSCALE MODELS ALL
INDICATE INCREASED SUPPORT FOR HIGH WIND WARNING LEVEL WINDS IN THE
LAS VEGAS VALLEY AS WELL AS MUCH OF SOUTHERN NEVADA AND NORTHWEST
ARIZONA ON SUNDAY...PARTICULARLY DURING THE AFTERNOON HOURS. THE GFS
HAS CONTINUED TO BE WEAKER WITH THE SYSTEM AND SLIGHTLY MORE
PROGRESSIVE. BASED ON WINDS OBSERVED AND CURRENT TRENDS HAVE
WEIGHTED MORE HEAVILY ON THE NAM SOLUTION. BOTH MODELS ARE
INDICATING 40+ KNOTS A FEW THOUSAND FEET ABOVE THE SURFACE...AND
WITHIN A FEW HOURS OF SUNRISE... ANTICIPATE THOSE WINDS BEING ABLE
TO MIX TO THE SURFACE. NOT ALL LOCATIONS WILL LIKELY SEE HIGH WIND
WARNING LEVEL WINDS IN THE LAS VEGAS VALLEY...BUT LOCATIONS IN THE
LEE OF THE SPRING MOUNTAINS WILL SEE ENHANCEMENT AS WELL AS THOSE
ACROSS THE SOUTHERN PORTIONS OF THE VALLY IN HENDERSON AND SEVEN
HILLS. THEREFORE...HAVE GONE AHEAD UPGRADED MUCH OF CLARK COUNTY AND
MOHAVE COUNTY TO A HIGH WIND WARNING FOR SUNDAY. THE COLORADO RIVER
VALLEY ZONES WILL REMAIN IN A WIND ADVISORY.
.PREV UPDATE...DOWNSLOPE WINDS HAVE DEVELOPED IN THE LEE OF THE
SIERRA WITH SEVERAL SENSORS OBSERVING WIND SPEEDS OF 40 TO 55 MPH IN
THE LAST HOUR. HAVE ISSUED A WIND ADVISORY FOR THE EASTERN SIERRA
AND THE OWENS VALLEY. EXPECT WINDS TO PERSIST FOR SEVERAL HOURS THIS
EVENING. WINDS MAY RELAX SOMEWHAT OVERNIGHT...BUT WILL ONCE AGAIN
REACH WIND ADVISORY LEVELS TOMORROW MORNING. WINDS HAVE ALSO BECOME
ENHANCED IN THE LEE OF THE SPRING MOUNTAINS IN THE LAS VEGAS
VALLEY...WITH THE RED ROCK CANYON RAWS SENSOR OBSERVING A WIND GUST
TO 43 MPH. EXPECT THIS INCREASING TREND TO CONTINUE THIS EVENING.
.PREV DISCUSSION...UPPER TROUGH OFF THE WEST COAST WILL CONTINUE
TO DIG SOUTH TONIGHT WITH TROUGH AXIS ALONG THE CALIFORNIA COAST
AROUND 12Z SUNDAY...AND THEN ROUGHLY OVER EASTERN NEVADA BY 00Z
MONDAY. PRECIPITATION TO SPREAD ACROSS MAINLY THE NORTHERN TWO
THIRDS OF THE CWA TONIGHT/SUNDAY AS THE TROUGH SHIFTS EAST AND
ALTHOUGH LOCALLY HEAVY SNOWFALL POSSIBLE IN THE SOUTHERN SIERRA AND
LINCOLN COUNTY MOUNTAINS...OVERALL AMOUNTS SHOULD REMAIN BELOW
ADVISORY LEVELS. DECREASE STABILITY WILL ALSO BRING A CHANCE FOR
ISOLATED THUNDERSTORMS TO THE NORTH OVERNIGHT AND SUNDAY. HOWEVER
THE MAIN CONCERN WITH THIS SYSTEM WILL BE WINDS. STRONG FLOW ALOFT
AS THE SYSTEM SHIFTS ACROSS THE AREA...ALONG WITH INCREASED SURFACE
PRESSURE GRADIENTS AND THERMAL GRADIENTS TO MAKE FOR A WINDY PERIOD
THROUGH SUNDAY. THE STRONGEST WINDS TO BE ACROSS THE SAN BERNARDINO
COUNTY DESERT ON SUNDAY...HOWEVER LOCAL DOWNSLOPE WINDS ARE LIKELY
TO FORM ON THE LEE SIDE OF THE SPRING MOUNTAINS AND THE SHEEP RANGE
TONIGHT AND EARLY SUNDAY. WILL UPGRADE HIGH WIND WATCHES FOR THESE
AREAS TO HIGH WIND WARNINGS. MEANWHILE CURRENT WIND ADVISORIES STILL
LOOK GOOD ELSEWHERE. WITH THE TROUGH AXIS SHIFTING EAST SUNDAY
NIGHT/COLD FRONT MOVING ACROSS SOUTHERN NEVADA...WINDS TO SWITCH TO
THE NORTH. GUSTY WINDS POSSIBLE WITH THE PASSAGE OF THE COLD
FRONT...BUT MAIN CONCERN WILL BE NORTH WIND PRONE AREAS MONDAY
AFTERNOON. FOR NOW WILL HOLD OFF ON ANY POSSIBLE ADVISORIES UNTIL
CURRENT ONES AREA OVER. INCREASED CLOUDS ON SUNDAY AND THEN COLD AIR
ADVECTION BEHIND THE FRONT WILL BE DROPPING THE WELL ABOVE NORMAL
TEMPERATURES OF THE PAST SEVERAL DAYS TO NEAR OR SLIGHTLY BELOW
NORMAL WITH MOST READINGS LOWERING 10 TO 15 DEGREES ON SUNDAY AND
CONTINUING INTO THE FIRST OF THE WEEK.
&&
.LONG TERM...THE AREA WILL REMAIN UNDER A DRY NORTHWEST FLOW ON
TUESDAY WHICH WILL HELP KEEP TEMPERATURE A DEGREE OR TWO BELOW
NORMAL. MODELS ARE SHOWING A SYSTEM DROPPING SOUTH OUT OF WESTERN
CANADA AND INTO THE GREAT BASIN WEDNESDAY. THE MODELS HAVE BEEN
FLIPPING OVER THE PAST 24 HOURS AND HAVE NOW BROUGHT THE SYSTEM
FURTHER WEST. THE 12Z GFS ENSEMBLE RUN SHOW MOST MEMBERS IN LINE
WITH THE OPERATIONAL GFS. EVEN THE GEM AND ECMWF HAVE BROUGHT THIS
SYSTEM FURTHER WEST. UNTIL A BETTER RUN TO RUN CONSISTENCY COMES
INTO PLAY...WILL NOT MAKE MANY CHANGES TO THE GRIDS. THIS SYSTEM IS
NOT EXPECTED TO BRING A LOT OF MOISTURE...BUT THE BEST CHANCES WOULD
REMAIN OVER THE EASTERN HALF OF THE CWA. THIS SYSTEM HAS THE
POTENTIAL OF BRINGING STRONG NORTH WINDS TO THE CWA THURSDAY AS A
STRONG COLD FRONT MOVES THROUGH THE REGION. IMPRESSIVE THERMAL
GRADIENTS THURSDAY MORNING WITH 0 DEG C OVER THE SOUTHERN CWA AND
-13 DEG C OVER THE NORTHERN CWA. TEMPERATURES WOULD ALSO COOL TO
SEVERAL DEGREES BELOW NORMAL BEHIND THE FRONT. THE AREA WILL REMAIN
UNDER A NORTHWEST FLOW FRIDAY AND SATURDAY RESULTING IN DRY
CONDITIONS AND COOL TEMPERATURES.
&&
.FIRE WEATHER...STRONG AND GUSTY WINDS WILL FORM ACROSS THE SAN
BERNARDINO COUNTY DESERTS ON SUNDAY WITH WINDY CONDITIONS ELSEWHERE
AS A STRONG PACIFIC STORM MOVES ACROSS THE DISTRICT. WIND GUSTS IN
EXCESS OF 50 MPH ARE EXPECTED ACROSS THE DESERT REGION OF SOUTHEAST
CALIFORNIA WITH POSSIBLE GUSTS REACHING 70 MPH. HOWEVER...COOLER
TEMPERATURES AND A SLIGHT INCREASE IN MOISTURE WILL ALLOW MINIMUM
RELATIVE HUMIDITY VALUES TO STAY ABOVE THE CRITICAL 15 PERCENT MARK
WHILE FUEL MOISTURE APPEARS NOT TO MEET THE VERY DRY CRITERIA AS OF
YET. THUS WILL MONITOR FOR NOW AND NOT ISSUE ANY FIRE WEATHER
PRODUCTS.
&&
.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS WILL CONTINUE INTO THE
EVENING AROUND 12-16KTS WITH GUSTS AROUND 24KTS. THESE WINDS WILL
DECREASE SLIGHTLY OVERNIGHT BEFORE INCREASING AGAIN ON SUNDAY.
STRONGEST WINDS ARE EXPECTED AFTER 15Z SUNDAY WITH SUSTAINED WINDS
OF 25-35KTS WITH OCCASIONAL GUSTS OVER 45KTS. A COLD FRONT WILL PASS
THROUGH SOUTHERN NEVADA SUNDAY NIGHT WITH WINDS BECOMING NORTHWEST
LATE. IN THE LAS VEGAS VALLEY IT LOOKS LIKE THE FRONT WILL PASS
THROUGH DRY...HOWEVER A FEW SHOWERS MAY BE AROUND THE NEARBY
MOUNTAINS AS WELL AS IN THE MORMON MESA AND BEATTY APPROACH
CORRIDORS. STRONG MID AND UPPER LEVEL WINDS ESPECIALLY ON SUNDAY
AFTERNOON AND EVENING WILL CREATE THE POTENTIAL FOR MECHANICAL
TURBULENCE ALOFT. THERE IS ALSO THE POTENTIAL OF A STRONG DOWNSLOPE
WIND EVENT ON THE EASTERN SLOPES OF THE SPRING MOUNTAINS BETWEEN
04Z-08Z TONIGHT. WINDS EXCEEDING 50KTS WILL BE POSSIBLE.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...GUSTY SOUTHWEST WINDS OF 15-25KTS WITH GUSTS NEAR 35
KTS WILL CONTINUE THROUGH TONIGHT BEFORE STRONGER WINDS ARRIVE
ON SUNDAY. THERE MAY BE A BRIEF LULL IN THE WINDS OVERNIGHT
TONIGHT...BUT STILL REMAIN AROUND 10-20KTS. GUSTY SOUTHWEST WINDS ON
SUNDAY COULD EXCEED 60 KTS ESPECIALLY IN SAN BERNARDINO COUNTY. THUS
BLOWING DUST IS POSSIBLE REDUCING VSBY. THIS FRONT WILL ALSO BRING
THE POTENTIAL FOR SHOWERS TO MAINLY NORTHERN PARTS OF THE AREA AND
AN ISOLATED TSTM THERE...IS NOT OUT OF THE QUESTION. THE FRONT WILL
PASS THROUGH SUNDAY NIGHT WITH GUSTY NORTH WINDS BEHIND IT.
