WINDS WILL DIMINISH BY MONDAY AFTERNOON AS AN AREA OF HIGH PRESSURE BUILDS OVER THE REGION AND HOLDS THROUGH THE MIDDLE OF THE WEEK FOR TRANQUIL WEATHER AND NEAR NORMAL TEMPERATURES. && .SHORT TERM...OBSERVATIONAL TOOLS INDICATE THE SYSTEM WAS COMING THROUGH THE AREA ABOUT AS DEPICTED...ESPECIALLY BY THE 12Z/18Z ETA. WATER VAPOR IMAGERY SHOWED THE VORT MAX IN THE BASE OF THE UPPER TROUGH JUST WEST OF LAS VEGAS AT 2230Z AND A SURFACE ANALYSIS SHOWED THE FRONT EXTENDING FROM SOUTHERN NYE UP THROUGH NORTHERN LINCOLN COUNTY. WILL SEE A QUICK SHOT OF SHOWERS THROUGH EARLY EVENING OVER SOUTHERN NEVADA WITH SNOW ALREADY FALLING IN THE MOUNTAINS. MAX SNOW ACCUMULATIONS SHOULD ONLY BE 2-3 INCHES WITH THE FAST MOVING SYSTEM SO NO ADVISORY PLANNED. WINDS PRECEDING THE FRONT SHOULD STILL BE AT ADVISORY LEVELS ACROSS THE SAN BERNARDINO COUNTY DESERTS THROUGH THIS EVENING AND WILL KEEP ADVISORY IN EFFECT. PRECIP OVER NORTHWEST ARIZONA WILL LIKELY END BY MIDNIGHT AND THE MAIN WEATHER FACTOR OVERNIGHT WILL BE NORTH WINDS BEHIND THE FRONT. HIGH PRESSURE BUILDING IN BEHIND THE SYSTEM MONDAY WILL BE THE DOMINANT FEATURE THROUGH WEDNESDAY. COLD AIR IN PLACE WILL AGAIN SET UP VALLEY INVERSIONS AS WINDS DIMINISH. && .LONG TERM...MODELS ARE IN FAIR AGREEMENT THURSDAY WITH SHORTWAVE RIDGING CONTINUING OVER THE CWA...WITH JUST SOME HIGH CLOUDS SPILLING OVER AND ACROSS THE REGION. MODELS BEGIN TO SHOW SIGNIFICANT DIFFERENCES FROM THEN ON AND ALL SEEM TO BE HAVING CONTINUITY PROBLEMS. SOME GFS RUNS AND THE EURO INDICATE A SHORTWAVE WILL MOVE INTO THE PACNW FRI MORNING WITH ASSOCIATED TROUGHING MOVING ONTO THE WEST COAST. 12Z GFS SHOWS MUCH DEEPER...CLOSED... SYSTEM BUT THIS SOLUTION DIFFERS GREATLY FROM THE 00Z AND 06Z RUNS OF THE SAME MODEL AND IS NOT SUPPORTED BY ANY OTHER MODELS AT THIS TIME. WENT WITH THE GFS ENSEMBLE MEAN FOR LACK OF BETTER SOLUTION FOR SAT AND SUN...AND LEANED A LITTLE TOWARDS THE 06Z OPERATIONAL RUN. THIS WOULD SPREAD PRECIPITATION AHEAD OF AN APPROACHING TROUGH ON FRIDAY...SWING THE FAST MOVING SYSTEM THROUGH ON SAT MORNING...AND BUILD A RIDGE OVER THE REGION BY SUNDAY. BUMPED UP TEMPS A LITTLE ABOVE 00Z MEX GUIDANCE SINCE OPERATIONAL GFS WAS THE DEEPEST AND COLDEST SOLUTION OF ALL MEMBERS. ALSO KEPT PRECIP CONFINED TO THE NORTHERN ZONES SINCE ENSEMBLE HINTS AT A WEAKER SYSTEM THAN THE OPERATIONAL MODELS. WILL LIKELY HAVE TO ADJUST FORECAST OVER THE NEXT FEW DAYS AS MODELS COME INTO BETTER AGREEMENT. .AVIATION...GUSTY SOUTHWEST WINDS WILL CONTINUE THROUGH THE AFTERNOON AND EVENING.
