AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
644 AM PST SAT FEB 23 2013

.SYNOPSIS...A COLD FRONT WILL PUSH SOUTHEAST ACROSS THE AREA THIS
AFTERNOON AND EVENING...RESULTING IN INCREASED NORTHERLY WINDS AND
COOLER TEMPERATURES TONIGHT AND SUNDAY. ANOTHER WEAK SYSTEM WILL
PUSH ACROSS THE REGION LATE MONDAY INTO TUESDAY BEFORE A RIDGE OF
HIGH PRESSURE ALLOWS TEMPERATURES TO CLIMB ABOVE NORMAL BY LATE NEXT
WEEK.
&&

.UPDATE...QUICK UPDATE TO INCREASE SKY COVERAGE ACROSS THE AREA AS
A BIT MORE HIGH CLOUD COVER HAS DEVELOPED THAN ANTICIPATED
EARLIER. THE COLD FRONT CONTINUE TO PUSH SOUTHEAST ACROSS CENTRAL
NEVADA THIS MORNING AND SHOULD ENTER THE CWA IN ESMERALDA COUNTY
IN THE NEXT HOUR OR SO. WINDS BEHIND THE FRONT HAVE GENERALLY BEEN
IN THE 10-20 KT RANGE WITH GUSTS TO 20-30 KTS. HOWEVER A GUST TO
53 MPH WAS RECORDED AT EUREKA ROUGHLY AN HOUR AGO AS THE FRONT
PASSED. WILL HOLD OFF ON ISSUING ANY WIND PRODUCTS AT THIS
TIME...BUT WILL ISSUE A NOWCAST FOR OUR NORTHERN ZONES AND
CONTINUE TO MONITOR.
&&

.PREV DISCUSSION...
339 AM PST SAT FEB 23 2013

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...LATEST SATELLITE LOOPS
SHOWED AN AREA OF MID AND HIGH LEVEL CLOUDS MOVING SOUTHEAST ACROSS
THE SOUTHERN GREAT BASIN. THESE CLOUDS HAVE FORMED IN ADVANCE OF A
SHORTWAVE DISTURBANCE THAT WILL PUSH A COLD FRONT ACROSS THE
FORECAST AREA THIS AFTERNOON AND EVENING. AS OF 09Z THIS MORNING THE
FRONT WAS JUST ENTERING THE NORTHWEST CORNER OF NEVADA AND IS
EXPECTED TO REACH THE NORTHERN FRINGES OF THE FORECAST AREA AROUND
15Z. THE FRONT WILL CONTINUE TO PUSH SOUTHEAST...REACHING THE LAS
VEGAS VALLEY AROUND 00Z PLUS OR MINUS AN HOUR THIS EVENING...THEN
FINALLY EXITING THE FORECAST AREA TO THE SOUTH BY 08Z SUNDAY.

AHEAD OF THE FRONT GUSTY WEST TO SOUTHWEST WINDS ARE EXPECTED...
ESPECIALLY ACROSS WESTERN SAN BERNARDINO COUNTY...WHERE A BRIEF
PERIOD OF WIND GUSTS TO 35-40 MPH WILL BE POSSIBLE BETWEEN 20Z AND
00Z. CURRENT THINKING IS THAT THE DURATION OF THESE WINDS WILL NOT
BE SUFFICIENT TO WARRANT A WIND ADVISORY. IN ADDITION...GUSTY NORTH
WINDS WILL BE POSSIBLE BEHIND THE FRONT...AGAIN WITH THE POTENTIAL
FOR GUSTS TO 40 MPH. WILL LET THE DAY SHIFT MONITOR TRENDS ACROSS
NORTHERN AND CENTRAL NEVADA BEFORE ISSUING ANY ADVISORIES FOR WINDS
ACROSS ESMERALDA...LINCOLN...CENTRAL NYE...OR NORTHERN CLARK
COUNTIES. AS FOR PRECIPITATION...EXPECTING RAIN AND SNOW TO REMAIN
CONFINED TO THE NORTHERN FRINGES OF THE CWA INCLUDING LINCOLN AND
CENTRAL NYE COUNTIES...POSSIBLY EVEN INTO NORTHERN MOHAVE COUNTY.
ACCUMULATING SNOW WILL LIKELY REMAIN CONFINED TO AREAS ABOVE 4500
FEET...HOWEVER WITH LIMITED MOISTURE AM NOT EXPECTING SIGNIFICANT
ACCUMULATIONS. OTHERWISE JUST EXPECTING SOME SCATTERED/BROKEN MID
AND HIGH LEVEL CLOUDS ACROSS THE AREA TODAY.

THE PRESSURE GRADIENT WILL BE INCREASING AS THIS FRONT PUSHES SOUTH
AND WILL LEAD TO GUSTY NORTHERLY WINDS DOWN THE COLORADO RIVER
VALLEY BY LATE THIS EVENING THROUGH THE OVERNIGHT HOURS. LAKE WIND
ADVISORY OR EVEN A WIND ADVISORY MAY BE NEEDED FOR THIS AREA BUT
WILL LET THE DAY SHIFT HANDLE THIS WITH THE POSSIBILITY OF
ADDITIONAL WIND ADVISORIES TODAY.

TEMPERATURES WILL REMAIN NEAR OR SLIGHTLY ABOVE NORMAL...THEN HIGHS
ARE EXPECTED TO DROP 6-8 DEGREES SUNDAY IN THE WAKE OF THE COLD
FRONT THEN BEGIN A SLOW RECOVERY MONDAY AS A SHORTWAVE RIDGE
PASSES OVER THE AREA. ANOTHER WEAK SHORTWAVE WILL PASS TO THE
NORTHEAST OF THE AREA MONDAY NIGHT. THIS FEATURE APPEARS
DRY...ONLY BRINGING A REINFORCING SHOT OF NORTH WINDS TO THE AREA.

.LONG TERM...TUESDAY THROUGH SATURDAY....A FAST MOVING OPEN THROUGH
WILL MOVE THROUGH THE REGION ON WEDNESDAY AND THURSDAY. AT THIS
TIME THE MODELS SEEM TO AGREE THAT THIS SYSTEM WILL NOT BRING ANY
PRECIPITATION TO THE REGION.  THE MAIN IMPACT OF THE MID-WEEK SYSTEM
WILL BE PERIODS OF GUSTY NORTH WIND...PARTICULARLY IN AREAS
SUSCEPTIBLE TO NORTH WINDS SUCH AS THE COLORADO RIVER VALLEY.  THERE
WILL BE A WARMING TREND AT THE END OF THE LONG TERM AS A RIDGE
BUILDS IN TO THE AREA...ALTHOUGH THE ECMWF IS SLIGHTLY SLOWER AT
BRINGING THE RIDGE IN TO THE AREA.
&&

.AVIATION...FOR MCCARRAN...THE MAIN ISSUE FOR MCCARRAN TODAY WILL
BE THE PASSAGE OF A COLD FRONT. GUSTY SOUTHWEST WINDS OF 10 TO 20
KNOTS WILL DEVELOP AROUND 21Z IN ADVANCE OF THE FRONT. THERE WILL
LIKELY BE A BRIEF LULL IN THE WINDS IMMEDIATELY BEFORE FRONTAL
PASSAGE...THE WINDS WILL THEN SHIFT TO THE NORTH AT AROUND 00Z ON
SUNDAY AS THE FRONT ARRIVES AT MCCARRAN. SCATTERED TO BROKEN
CLOUDS AOA 20K FT. NO PRECIPITATION IS EXPECTED AT KLAS TODAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SOUTHWEST WINDS WILL INCREASE ACROSS THE AREA SATURDAY
MORNING WITH SPEEDS UP TO 25 WITH GUST UP TO 40 KTS IN WESTERN SAN
BERNARDINO COUNTY...INCLUDING KDAG. A COLD FRONT WILL PUSH THROUGH
THE REGION WITH NORTHWEST WINDS WITH GUSTS UP TO 35 KTS BEHIND THE
FRONT. NORTHWEST WINDS WITH GUSTS UP TO 35 KTS WILL CONTINUE DOWN
THE COLORADO RIVER VALLY DURING THE OVERNIGHT HOURS...INCLUDING
KEED. HIGH CLOUDS WILL INCREASE THROUGH SATURDAY.
