AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 935 AM PST WED FEB 2 2011 .SYNOPSIS...A LOW PRESSURE SYSTEM OVER EASTERN ARIZONA WILL CONTINUE TO BRING VERY COLD AIR AND GUSTY WINDS TO THE REGION TODAY WITH THE STRONGEST WINDS OVER THE COLORADO RIVER VALLEY. WINDS WILL DECREASE ON THURSDAY...HOWEVER BELOW FREEZING TEMPERATURES ARE STILL EXPECTED THURSDAY MORNING. A WARMING TREND WILL THEN TAKE PLACE INTO THE WEEKEND AS HIGH PRESSURE BUILDS OFF THE WEST COAST. && .UPDATE...BRRRRRRRRR! THIS WAS THE COLDEST MORNING OF THE YEAR IN LAS VEGAS AND OFFICIALLY THE COLDEST MORNING SINCE JANUARY 2007. EVEN NORMALLY WARM MCCARRAN AIRPORT DROPPED TO 26 DEGREES. THE COLDEST LOW IN THE VALLEY WE KNOW OF FROM A RELIABLE SOURCE WAS FROM ONE OF OUR OFF-DUTY EMPLOYEES IN THE MOUNTAIN'S EDGE NEIGHBORHOOD ON THE SOUTHWEST SIDE OF VEGAS WHO REPORTED 18 DEGREES AND THIS WAS AS OF 330 THIS MORNING. GIVEN IT GOT COLDER THAN EXPECTED LAST NIGHT I AM LIKELY GOING TO BE MAKING SOME ADJUSTMENTS TO LOWS FOR TONIGHT WITH THE AFTERNOON PACKAGE. THERE WILL BE LESS WIND AROUND...BUT SPOTS THAT TEND TO RADIATE VERY WELL ESPECIALLY IN LOW SPOTS WILL LIKELY BE EVEN COLDER TONIGHT. THE MAIN IMPACT OF THIS WILL BE A LONG DURATION FREEZE IN THE LOWER DESERT VALLEYS WITH MANY PLACES SEEING 8-12 HOURS OF AT OR BELOW FREEZING TEMPS. AS A SIDE NOTE...WE WILL BE POSTING A GRAPHIC AND MAYBE A STATEMENT RECAPPING THE COLD WX THIS MORNING ON OUR WEBSITE IN THE NEXT HOUR OR SO AS WELL AS POST SOMETHING BY MID-AFTERNOON HIGHLIGHTING THE IMPACTS OF THE COLD WX FOR TONIGHT. && .AVIATION...FOR MCCARRAN...MORNING MODEL DATA FORECASTS STRONGER NORTHEAST WINDS MIXING TO THE SURFACE BETWEEN NOW AND 19Z BECOMING 10-14 KTS WITH GUSTS OF 20-25 KTS AND LASTING THROUGH MUCH OF THE AFTERNOON. WINDS WILL THEN DECREASE BELOW 10 KTS BETWEEN 01Z-02Z AND BECOME VARIABLE UNDER 8 KTS OVERNIGHT. SKIES WILL REMAIN MOSTLY CLEAR. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...NORTHEAST TO EAST WINDS EXPECTED THROUGH THIS AFTERNOON WITH SPEEDS GENERALLY 10-18 KTS. STRONGER NORTH WINDS ARE EXPECTED TO CONTINUE DOWN THE COLORADO RIVER VALLEY THROUGH THE AFTERNOON WITH SPEEDS OF 20-30 KTS AND GUSTS AROUND 35 KTS. WINDS WILL GRADUALLY DIMINISH LATE THIS AFTERNOON AND EVENING. SKIES WILL REMAIN MOSTLY CLEAR. && .PREVIOUS DISCUSSION...ISSUED AT 245 AM PST WED FEB 2 2011 .SHORT TERM...TODAY THROUGH FRIDAY NIGHT...UPPER LOW OVER THE FOUR CORNER STATES WILL CONTINUE TO DROP SOUTH INTO SOUTHEAST ARIZONA DURING THE DAY BEFORE SHIFTING EAST ON THURSDAY. THIS WILL RESULT IN CONTINUED VERY COLD NORTHEAST FLOW ACROSS THE CWA TODAY WITH LITTLE MODIFICATION ON THURSDAY AS THE FLOW ALOFT SLOWLY TURNS MORE NORTHERLY. BY FRIDAY...RIDGING OFF THE WEST COAST WILL CONTINUE TO KEEP NORTHERLY FLOW ACROSS THE CWA...HOWEVER HEIGHTS/THICKNESS RISES WILL BRING WARMER CONDITIONS TO THE REGION WHICH WILL THEN CONTINUE INTO THE LONG TERM. FOR THE SHORT TERM HOWEVER THE MAIN CONCERN WILL CONTINUE TO WINDS AND COLD TEMPERATURES. ALTHOUGH LOCAL GUSTY NORTH WINDS WILL CONTINUE ACROSS MUCH OF THE CWA TODAY...THE MAIN AREA WILL CONTINUE TO BE THE COLORADO RIVER VALLEY AND THE EXTREME EASTERN PORTION OF SAN BERNARDINO COUNTY. WIND GUSTS TO 40 MPH OR GREATER ARE EXPECTED TO CONTINUE BEFORE DECREASING OVERNIGHT AND INTO THURSDAY. NORTH WINDS HOWEVER WILL CONTINUE UNDER THE NORTHERLY FLOW THROUGH THE SHORT TERM. VERY COLD AIR OVER THE AREA WILL ALLOW FOR A 15-20 DEGREE DROP IN TODAYS HIGHS OVER THOSE ON TUESDAY...RESULTING IN MOST DAYTIME TEMPERATURES BEING 15 TO 25 DEGREES BELOW NORMAL FOR THIS AFTERNOON. THIS COLD AFTERNOON COMBINED WITH LESS WINDS TONIGHT WILL ONCE AGAIN ALLOW FOR BELOW FREEZING TEMPERATURES IN THE LOWER DESERT AREA ON THURSDAY MORNING. AS THE MAIN TROUGH SHIFTS OUT OF THE AREA AND THE RIDGE BUILDS OFF THE WEST COAST...DAYTIME TEMPERATURES WILL WARM TO NEAR NORMAL BY FRIDAY AFTERNOON. .LONG TERM....HIGH PRESSURE CENTERED OFF THE NORTHERN CALIFORNIA COAST IS EXPECTED TO REMAIN NEARLY STATIONARY THROUGH THE EXTENDED PERIOD. THIS WILL KEEP A DRY NORTHERLY FLOW OVER MUCH OF THE AREA AND KEEP TEMPERATURES A FEW DEGREES ABOVE NORMAL. A WEAK SHORTWAVE MOVING SOUTHEAST OUT OF THE PACIFIC NORTHWEST MAY BRUSH THE FAR EASTERN AREAS OF THE CWA LATE SATURDAY AND SUNDAY. THE IMPACTS ARE EXPECTED TO BE MINIMAL AND MAY BRING A FEW MORE CLOUDS TO THE EASTERN HALF OF LINCOLN COUNTY. SURFACE WINDS WILL REMAIN OUT OF THE NORTH THROUGH THE PERIOD AND ARE LIKELY TO KEEP GUSTY WINDS DOWN THE COLORADO RIVER VALLEY. && .VEF WATCHES/WARNINGS/ADVISORIES...
