NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Nov 7, 10:00 AM PST, 3 hours 30 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE LAS VEGAS NV 1000 AM PST SUN NOV 7 2004 .SYNOPSIS...AN AREA OF LOW PRESSURE WILL MOVE THROUGH THE SOUTHERN GREAT BASIN AND MOJAVE DESERT THIS AFTERNOON AND TONIGHT. THIS SYSTEM IS EXPECTED TO BRING SIGNIFICANT AMOUNTS OF VALLEY RAIN AND MOUNTAIN SNOW TO MUCH OF THE AREA TONIGHT AND EARLY MONDAY. DRIER CONDITIONS ARE EXPECTED TUESDAY AS THE LOW SHIFTS EAST INTO UTAH AND COLORADO. && .UPDATE...FAIRLY WIDESPREAD RAIN WAS ALREADY INDICATED BY RADAR OVER MOHAVE COUNTY THIS MORNING AND MANY AUTOMATED SITES HAD REPORTED MEASURABLE RAINFALL...A FEW MORE THAN 0.25 INCHES. ALSO RECEIVED A REPORT OF LESS THAN AN INCH OF SNOW ON THE GROUND AT ASPENDELL IN THE EAST SLOPES OF THE SIERRA. UPSLOPE MOIST FLOW WILL ONLY INCREASE THERE TODAY AND ISSUED A SNOW ADVISORY. UPDATED GRIDS TO INCREASE POPS TO LIKELY OR CATEGORICAL FROM MOHAVE COUNTY UP THROUGH NORTHEAST CLARK AND LINCOLN TODAY. THE 12Z MODELS STILL INDICATE A BULLSEYE OF PRECIP FROM SOUTHERN MOHAVE COUNTY UP THROUGH SOUTHERN NEVADA TONIGHT. THIS COULD PROVE TO THE BEST PRECIP PRODUCER SO FAR FOR OUR AREA. && .AVIATION...A STRONG UPPER LOW OFF THE SOUTHERN CALIFORNIA COAST IS ALREADY BRINGING CLOUD COVER AND SPOTTY RAINFALL TO SOUTHERN NEVADA THIS MORNING. THE LOW WILL TRACK EAST TO NORTHEAST TODAY AND TONIGHT BRINGING WIDESPREAD PRECIPITATION TO THE AREA AS IT DOES. PRECIPITATION WILL BE NEAR KLAS AND THE LAS VEGAS VALLEY BY MID AFTERNOON WITH IT BEING A HIT OR MISS PROPOSITION FOR KLAS. RAIN WILL DEFINITELY BE OVER KLAS BY EARLY EVENING AND FOR THE REST OF THE NIGHT AND INTO MONDAY MORNING. DURING THE NIGHT HOURS CEILINGS WILL DROP BELOW THE 5000 FOOT LEVEL. DURING PERIODS OF MODERATE RAINFALL TONIGHT CEILINGS COULD EVEN DROP TO THE 2000 TO 3000 FOOT RANGE. CONDITIONS ARE EXPECTED TO IMPROVE MONDAY AFTERNOON. && .PREV DISCUSSION...300 AM PST...BIG CHANGES FROM THE PREVIOUS FORECAST WITH THE MODELS NOW SHOWING A SIGNIFICANT BAND OF QPF STRETCHING FROM SOUTHERN MOHAVE COUNTY THROUGH SOUTHERN NEVADA AND INTO ESMERALDA COUNTY. THE LOW CURRENTLY NEAR 31N/122W AND STARTING TO SHOW SIGNS OF TURNING MORE EAST...WHICH THE MODELS SHOW BETWEEN 12/18Z THIS MORNING. THIS SYSTEM HAS TAPPED INTO A SIGNIFICANT BAND OF SUBTROPICAL MOISTURE AND SHOWERS ARE ALREADY STARTING TO SHOW UP OVER EXTREME SOUTHERN MOHAVE COUNTY. AS THIS LOW MOVES INTO SOUTHERN CALIFORNIA IT SETS UP A LARGE AREA OF UPPER DIFFLUENCE OVER SOUTHERN PORTIONS OF THE CWA. MOISTURE WILL BEGIN TO WRAP AROUND THE LOW THIS AFTERNOON AND REALLY ENHANCE TONIGHT WITH THE BEST FORCING EXPECTED BETWEEN 03Z AND 12Z. LOOK LIKE THE BEST CHANCE OF PRECIPITATION WILL BE ALONG THE NV/CA BORDER EAST. SAN BERNARDINO AND THE VALLEYS OF INYO COUNTY WILL LIKELY MISS THE BEST PRECIP CHANCES AS A DRY SLOT WILL WORK INTO THOSE AREAS. HOWEVER THE MOUNTAINS OF INYO COUNTY (ESPECIALLY THE SIERRA) COULD SEE A GOOD UPSLOPE EVENT AND COULD SEE DECENT PRECIP AMOUNTS. SNOW LEVELS ARE EXPECTED TO REMAIN HIGH FOR THOSE AREAS AND ANY STATEMENT WILL NOT BE NEEDED AT THIS TIME. THUNDERSTORM HAVE ALREADY DEVELOPED THIS MORNING JUST OFF THE SO CA COAST AND WILL TRACK THOSE EAST WITH THE LOW TODAY AND MENTION A SLIGHT CHANCE OF THUNDERSTORMS FOR THE REGION TODAY AND TONIGHT. THERE IS NOT A LOT OF COLD AIR AWAY FROM THE LOW AND ONLY AREA DIRECTLY UNDER THE LOW CENTER SHOULD SEE FAIRLY LOW SNOW LEVELS. THIS WILL LEAVE THE MOUNTAINS OF SOUTHERN NEVADA WITH THE BEST CHANCE OF SEEING SIGNIFICANT SNOW AMOUNTS TONIGHT AND MONDAY. HAVE GONE AHEAD AND UPGRADED THE WATCH TO A WARNING WITH 12 TO 16 INCHES OF SNOW EXPECTED BY MONDAY AFTERNOON. HAVE ELECTED TO LEAVE LINCOLN AND MOHAVE COUNTIES OUT OF ANY WEATHER ADVISORIES DUE TO THE HIGH SNOW LEVELS WHICH SHOULD REMAIN OVER 8000 FEET DURING THE GREATEST PRECIPITATION THREAT. THE LOW IS EXPECTED TO MOVE OVER THE AREA MONDAY AND MOST PLACES OVER THE SOUTHERN CWA WILL SEE ISOLATED THUNDERSTORMS. THE LOW IS FORECAST TO MOVE EAST TUESDAY WITH ONLY THE FAR EASTERN SECTIONS OF THE CWA SEEING ANY PRECIP CHANCES. THIS ONLY LEADS INTO THE NEXT IN A SERIES OF LOWS THAT DROP DOWN THE WEST COAST. && .LONG TERM...MODELS CONTINUE TO AGREE ON THE SECOND STRONG SHORTWAVE /THE KICKER FOR OUR CURRENT STORM/ DIGGING DOWN THE COAST MIDWEEK. THERE ARE SOME INTERESTING RUN TO RUN MODEL TRENDS WITH THIS SYSTEM...THE NEWER RUNS ARE SLOWER AND FARTHER EAST. THE 00Z GFS AND ECMWF AND THE 06Z DGEX ARE TIGHTLY CLUSTERED WITH THE LOW CENTER...SHOWING IT NEAR BAKERSFIELD THURSDAY AFTERNOON AND OVER THE LOWER COLORADO RIVER VALLEY FRIDAY AFTERNOON. THIS WOULD SUGGEST SOME CHANCE OF PRECIP STARTING OVER OUR CWFA AS EARLY AS THURSDAY...BUT WILL BEGIN PRECIP CHANCES ON FRIDAY FOR NOW IN ANTICIPATION OF FURTHER SLOWING IN FUTURE MODEL RUNS. SINCE CONFIDENCE IS NOT VERY GOOD IN THE EXACT LOCATION OR TIMING...KEPT THINGS DOWN AT SLIGHT CHANCE FOR NOW. TEMPS WILL BE BELOW SEASONAL AVERAGES AGAIN AS THIS LOW APPROACHES AND CROSSES THE CWFA. && .AVIATION...TAF ADEQUATELY COVERS CONDITIONS EXPECTED AT KLAS. && .VEF WATCHES/WARNINGS/ADVISORIES... .NV...WINTER STORM WARNING TONIGHT AND MONDAY NVZ018 AND NVZ019. .AZ...NONE. .CA...NONE. && ADAIR/JACQUES/GORELOW/MORGAN
