AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
231 PM PDT MON SEP 23 2013

.SYNOPSIS...WEAK RIDGING WILL LEAD TO A WARMING TREND THROUGH
TUESDAY. A STRONG AREA OF LOW PRESSURE SAGGING SOUTH INTO THE AREA
MID-WEEK WILL LEAD TO ANOTHER ROUND OF GUSTY WINDS...COOLER
TEMPERATURES...AS WELL AS A CHANCE OF PRECIPITATION ACROSS CENTRAL
NEVADA AND NORTHERN MOHAVE COUNTY. CONDITIONS WILL IMPROVE OVER THE
WEEKEND AS HIGH PRESSURE BUILDS OVER THE AREA ONCE AGAIN.
&&

.SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT...TRANSITORY RIDGE WILL
SHIFT EAST BY TUESDAY AS LONGWAVE TROUGH OVER THE GULF OF ALASKA
SAGS SOUTH INTO THE PACIFIC NORTHWEST. TEMPERATURES SHOULD JUMP
ANOTHER 5 TO 7 DEGREES WHICH WILL PUT THEM RIGHT AROUND NORMAL

APPROACHING TROUGH WILL ALSO START TO INFLUENCE SURFACE WINDS
TUESDAY AFTERNOON. HOWEVER...STRONGEST WINDS IN THE FORM OF STRONG
RIDGETOP OR DOWNSLOPE WINDS WILL NOT BE FELT UNTIL TUESDAY NIGHT. H5
70KT JET PROGGED TO BE ACROSS THE SRN SIERRA NEVADA BY 12Z WEDNESDAY
WITH THAT BELT OF WINDS SHIFTING SOUTHEAST ACROSS THE SPRING MTNS.
DUE TO THE LIKELIHOOD OF STRONG RIDGETOP WINDS AND THE POTENTIAL OF
DOWNSLOPE WINDS...DECIDED TO ISSUE A HIGH WIND WATCH FOR THE EASTERN
SIERRA SLOPES OF INYO COUNTY AND THE SPRING MOUNTAINS IN CLARK
COUNTY STARTING TUESDAY NIGHT AND CONTINUING INTO WEDNESDAY.

.LONG TERM...WEDNESDAY THROUGH SUNDAY...MAIN CHANGES IN THE PERIOD
ARE IN THE GREATER PROBABILITY OF ENHANCED DOWNSLOPE WINDS IN THE
LEE OF THE SPRING MOUNTAINS ON WEDNESDAY...PARTICULARLY IN THE

NORTHWESTERN PORTIONS OF THE LAS VEGAS VALLEY WITH THE STRONGEST
SIGNATURE...RATHER THAN THE ENTIRE WEST SIDE. WIND GUSTS IN EXCESS

AROUND THE SOUTH SIDE OF THE TROUGH AND ACROSS SAN BERNARDINO...
CLARK AND MOHAVE COUNTIES. MODELS INDICATING 40 TO 50 KTS AT 700 MB
ACROSS THE SOUTHERN HALF OF THE CWFA DURING THE DAY ON WEDNESDAY...
WHICH WILL AID IN PRODUCING WIND GUSTS OF SIMILAR SPEEDS AT THE
SURFACE. WIND ADVISORIES WILL LIKELY BE ISSUED IN THE NEXT 24 HOURS
FOR MUCH OF THE SOUTHERN HALF OF THE AREA INCLUDING THE LAS VEGAS
VALLEY. THE MODELS HAVE TRENDED SLIGHT FURTHER TO THE NORTH WITH THE
POSITIONING OF THE MAIN LOW ON WEDNESDAY...BUT THERE CONTINUES TO BE
A CHANCE OF SHOWERS AHEAD OF THE APPROACHING COLD FRONT ACROSS THE
NORTHERN FRINGES OF THE FORECAST AREA. BY THURSDAY...THE INSTABILITY
INCREASES ACROSS LINCOLN COUNTY AND NORTHERN MOHAVE COUNTY WHICH
WILL PROVIDE A CHANCE OF SHOWERS AND EVEN AN ISOLATED THUNDERSTORM.
THE COLD FRONT IS EXPECTED TO PUSH THROUGH THE LAS VEGAS VALLEY ON
THURSDAY MORNING AND THEN THROUGH THE ENTIRE FORECAST AREA BY
THURSDAY EVENING. GUSTY NORTH WINDS AND HIGH TEMPERATURES 15 TO 20
DEGREES BELOW NORMAL WILL MAKE IT FEEL LIKE FALL. A RIDGE OF HIGH
PRESSURE WILL BEGIN TO NOSE INTO THE SOUTHWEST ON FRIDAY AND WILL BE
IN PLACE OVER THE WEEKEND AND INTO THE START OF NEXT WEEK.
TEMPERATURES WILL BE TRENDING UPWARD BEGINNING FRIDAY AND WILL REACH
WITHIN A FEW DEGREES OF THE SEASONAL NORMS BY SUNDAY AND MONDAY.
&&
