AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
300 PM PDT FRI MAR 22 2013

.SYNOPSIS...LOCALLY GUSTY NORTHWEST TO NORTH WINDS ARE EXPECTED AT
TIMES ACROSS THE AREA THROUGH THE WEEKEND. ALTHOUGH BELOW NORMAL
TEMPERATURES ARE EXPECTED SATURDAY THROUGH MONDAY...READINGS WILL
REBOUND TO ABOVE NORMAL BY THE MIDDLE OF NEXT WEEK AS AN UPPER LEVEL
RIDGE BUILDS INTO THE SOUTHWEST.
&&

.SHORT TERM...SATELLITE LOOP SHOWED CLEAR SKIES AREAWIDE EARLY THIS
AFTERNOON. SURFACE OBS SHOWED BREEZY NORTH WINDS...EXTREMELY LOW
DEWPOINTS...AND TEMPERATURES GENERALLY CLOSE TO NORMAL. THE MAIN
CONCERN FOR THE SHORT TERM WILL BE WINDS. GUSTY NORTH WINDS WILL BE
FOCUSED DOWN THE COLORADO RIVER VALLEY OVER THE WEEKEND...WITH LAKE
WIND ADVISORY CONDITIONS POSSIBLE MAINLY ON SATURDAY. BREEZY NORTH
WINDS WILL ALSO OCCUR ELSEWHERE...BUT THE STRONGEST WINDS WILL
LIKELY BE DOWN THE RIVER. TEMPERATURES WILL BE UNSEASONABLY CHILLY
ON SATURDAY...WITH SOMEWHAT OF A WARMING TREND SUNDAY AND
MONDAY...BUT NOT ENOUGH TO GET TEMPERATURES BACK TO LATE MARCH
NORMALS. NO PRECIPITATION IS EXPECTED THROUGH MONDAY...AND CLOUD
COVER WILL BE LIMITED TO PERIODS OF HIGH CLOUDS.

.LONG TERM...MONDAY NIGHT THROUGH FRIDAY...THE AXIS OF A RIDGE OF
HIGH PRESSURE WILL BE MOVING EAST ACROSS THE FORECAST AREA AT THE
BEGINNING OF THE LONG TERM. MODELS HAVE BEGUN TO COME INTO BETTER
AGREEMENT ON A POTENTIALLY DEEP LOW PRESSURE SYSTEM THAT MAY IMPACT
THE REGION BY LATE NEXT WEEK. THIS WILL RESULT IN FLOW WILL
GRADUALLY BACKING TO THE SOUTHWEST TUESDAY THROUGH THURSDAY. DURING
THIS PERIOD ABOVE NORMAL TEMPERATURES AND OCCASIONAL HIGH CLOUDS ARE
EXPECTED ACROSS THE AREA. SOUTHWEST SURFACE WINDS WILL LIKELY
INCREASE EACH DAY ACROSS THE DESERT REGIONS SUCH AS WESTERN SAN
BERNARDINO COUNTY. THERE IS A CHANCE OF A COUPLE SHORTWAVES EJECTING
OUT AHEAD OF THIS SYSTEM...BUT AT THIS TIME HAVE KEPT THE FORECAST
DRY THROUGH THURSDAY NIGHT. AS BETTER DYNAMICS APPROACH THE REGION
FRIDAY THE CHANCES OF PRECIPITATION WILL INCREASE. HARD TO SAY AT
THIS POINT WHERE THE BEST PRECIPITATION POTENTIAL WILL BE OUTSIDE OF
THE SOUTHERN SIERRA...BUT HAVE INCREASED POPS AREAWIDE THROUGH THE
END OF THE LONG TERM PERIOD. AS IS USUAL WITH THIS TYPE OF
SYSTEM...SOUTHWEST WINDS ARE LIKELY TO BECOME BREEZY TO WINDY BY
LATE THURSDAY THROUGH FRIDAY. TOOK A BROAD-BRUSHED APPROACH TO THE
FORECAST WITH THIS PACKAGE DUE TO THE LIMITED RUN-TO-RUN MODEL
CONTINUITY.
&&

.AVIATION...FOR MCCARRAN...A WIDE VARIETY OF WINDS HAVE BEEN NOTED
AT KLAS THROUGHOUT THE DAY...AND WILL LIKELY CONTINUE INTO THIS
EVENING. MODELS CONTINUE TO SUGGEST THAT NORTHEAST WINDS WILL
DOMINATE THE VALLEY THROUGH ABOUT MIDNIGHT BEFORE SHIFTING TO THE
NORTHEAST. BASED ON TODAYS OBSERVATIONS...CANNOT RULE OUT THE
POSSIBILITY OF A SWITCH TO SOUTHWESTERLY DRAINAGE WINDS OVERNIGHT IF
THE NORTHERLY WINDS WEAKEN. NORTHEAST WINDS ARE EXPECTED SATURDAY
WITH GUSTY CONDITIONS POSSIBLE SATURDAY MORNING. MAINLY CLEAR SKIES
ARE EXPECTED OVER THE NEXT 24 HRS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...10-20KT WINDS FAVORING A NORTHERLY DIRECTION WILL
CONTINUE OVER MOST AREAS INTO THIS EVENING. WINDS ARE EXPECTED TO
DECREASE OVERNIGHT...EXCEPT DOWN THE COLORADO RIVER VALLEY...WHERE
WINDS ARE EXPECTED TO INCREASE AFTER MIDNIGHT. WINDS OF 20-25 KTS
WITH GUSTS TO 30-35 KTS ARE EXPECTED DOWN THE RIVER VALLEY SATURDAY
MORNING...BEGINNING TO DECREASE DURING THE AFTERNOON. SKIES WILL BE
GENERALLY CLEAR DURING THE PERIOD...WITH SOME HIGH CLOUDS
APPROACHING THE REGION BY SATURDAY AFTERNOON/EVENING.
