MOJAVE DESERT/SOUTHERN GREAT BASIN AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 303 AM PST SUN DEC 23 2001 SYNOPSIS...AN UPPER LOW OVER NORTHERN NEVADA WILL SLIDE THROUGH CENTRAL NEVADA AND INTO NORTHWEST ARIZONA DURING THE DAY. THIS WILL BRING SNOW TO SOUTH CENTRAL NEVADA WITH SCATTERED SHOWERS TO NORTHERN CLARK COUNTY. NORTHERLY WINDS WILL INCREASE BEHIND THIS SYSTEM LATER THIS AFTERNOON INTO TONIGHT. TEMPERATURES WILL BE SLIGHTLY BELOW NORMAL THROUGH MONDAY. DISCUSSION...LAST NIGHT EVERYBODY WAS SURE THE ETA WAS THE BETTER MODEL TO FOLLOW...INCLUDING MYSELF. MY ONLY CONCERN WAS THE STRENGTH OF THE JET ON THE BACK SIDE FORECAST BY ALL MODELS. WELL...THE AVN ENDED UP BEING A MUCH BETTER MODEL TO FOLLOW AND I HAVE CONVERTED TO IT THIS MORNING. HOWEVER...NEITHER MODEL INITIALIZED THE UPPER SYSTEM VERY WELL. THE ETA WAS BY FAR THE WORST WITH THE TEMPERATURE AND HEIGHT FIELDS (TEMPS TOO WARM...HEIGHTS NOT LOW ENOUGH) AROUND THE LOW. WITH THAT SAID...IM USING THE AVN WITH SOME MODIFICATIONS BASED ON CURRENT TRENDS AND INITIALIZATION PROBLEMS. UPPER AIR CHARTS STILL SHOWING 120 KNOT JET ON BACK SIDE OF SYSTEM LAST NIGHT. AVN SHOWS STRONG UPPER DIVERGENCE AND EVEN AN H7/H3 CONVERGENT/DIVERGENT COUPLET OVER NORTHERN MOHAVE COUNTY TODAY. DYNAMICS AROUND UPPER LOW ARE CREATING WIDESPREAD SNOW (MOSTLY LIGHT) OVER NORTHERN NYE AND POSSIBLY NORTHERN LINCOLN COUNTY. WILL BEEF UP POPS TO COVER THIS AND INDICATE ACCUMULATIONS OF AN INCH OR TWO FROM NORTHERN NYE THROUGH LINCOLN AND OVER INTO NORTHERN MOHAVE COUNTY. WINDS SHOULD DEVELOP QUICKLY BEHIND THIS SYSTEM UP NORTH THIS AFTERNOON AND SPREAD INTO SOUTHERN NEVADA AND NORTHWEST ARIZONA OVERNIGHT. WILL BEEF UP WORDING TO INDICATE SUCH. WINDS SHOULD CONTINUE TOMORROW DOWN THE COLORADO RIVER VALLEY WITH LESS WIND ELSEWHERE. DAY SHIFT WILL HAVE TO KEEP AN EYE ON THE WIND SITUATION FOR THE LAKES TONIGHT AND ALSO THE SOUTHERN OWENS VALLEY. RIGHT NOW IVE KEPT WINDS JUST BELOW ADVISORY CRITERIA ALONG THE LAKES TONIGHT INTO MONDAY BUT IT NEEDS TO BE CLOSELY MONITORED. ALSO...IM CONCERNED AGAIN WITH SOUTHERN INYO COUNTY LATE THIS AFTERNOON THROUGH TONIGHT. THE WIND CORRIDOR SOUTH OF OLANCHA WILL MOST LIKELY REACH WIND ADVISORY CRITERIA AND POSSIBLY APPROACH HIGH WIND IN A SMALL SECTION. THE CURRENT FORECAST INDICATES GUSTS TO 45 MPH THERE TONIGHT. AFTER THIS SYSTEM EXITS THE REGION TONIGHT...AN OMEGA BLOCK WILL CONTROL THE WEATHER THROUGH THE PERIOD. A WEAK LOW TRIES TO BREAK THROUGH UNDER THE RIDGE ON CHRISTMAS DAY IN CALIFORNIA BUT AS OF NOW EVERYBODY WANTS TO KEEP IT DRY. THE MODEL SOLUTIONS ARE SHOWING A LITTLE MORE ENERGY WITH THIS SYSTEM THAN LAST NIGHT BUT DRY IS STILL OK WITH ME. NO CHANGES TO EXTENDED NEEDED TONIGHT. SKRBAC .LAS...NONE.
