NWS Grand Junction, CO wrote its last area forecast discussion before the first event at Nov 30, 9:44 PM MST, 2 hours 16 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND JUNCTION CO 944 PM MST SUN NOV 30 2014 .UPDATE... ISSUED AT 938 PM MST SUN NOV 30 2014 THE NAM HAS VERIFIED WELL WITH THE PLACEMENT OF LIGHT FRONTAL SNOW THIS EVENING...STAYING IN EXTREME SOUTHERN WYOMING. BAGGS WY HAS HAD LOW CLOUD CEILINGS THROUGH THE EVENING BUT NO SNOW REPORTED. A DISTURBANCE BEST SEEN IN THE 300MB POT VORT FIELD IS MOVING THROUGH THE CENTRAL CWA THIS EVENING. THE 00Z MODELS ARE FAVORING A FEW INCHES OF SNOW OVER THE CASTLE PEAK RIDGE LINE INCLUDING MCCLURE PASS MARBLE GOTHIC AND ASHCROFT. ASPEN EAGLE AND EVEN GUNNISON COULD SEE LIGHT SNOW BEFORE SUNRISE. WILL ADD POPS THERE BETWEEN 06-12Z. OTHERWISE THE WEDNESDAY STORM IS LOOKING UNSTORM-LIKE. WITH ONLY LITTLE COLD AIR OR DYNAMICS AND ONLY LIGHT MOUNTAIN SNOW. RIGHT NOW HIGHLIGHTS DO NOT LOOK NEEDED BUT THIS IS WITHOUT A DETAILED ANALYSIS. THAT TO BE ACCOMPLISHED OVERNIGHT TONIGHT. && .SHORT TERM...(TONIGHT THROUGH MONDAY NIGHT) ISSUED AT 255 PM MST SUN NOV 30 2014 LOCAL WEBCAMS SHOWING SNOW FALLING ALONG A FRONTAL BAND OVER I-80 IN SRN WY THIS AFTERNOON AS CDOT WEBCAMS SHOW CLOUDS ALONG THE WY/CO BORDER. LATEST GUIDANCE SUGGESTING NOT MUCH MOVEMENT OF THIS FRONTAL BAND THROUGH MIDNIGHT SO LOWERED POPS TO THE SOUTH ACCOUNTING FOR THIS BEHAVIOR THOUGH AN ODD FLURRY FOR HIGHER ELEVATIONS UP NORTH NOT OUT OF THE QUESTION. A WEAK WAVE IS EXPECTED TO MOVE ACROSS THE REGION FROM THE WEST JUST AFTER MIDNIGHT THROUGH DAYBREAK CAUSING AN UPTICK IN PRECIP FOR THE NRN AND CENTRAL MTNS SO A COUPLE OF INCHES POSSIBLE OVERNIGHT BUT NOTHING TOO SIGNIFICANT. TEMPERATURES REMAIN ON THE WARM SIDE. IN FACT...GRAND JUNCTION HAS REACHED 57 DEGREES F THIS AFTERNOON...ONE DEGREE SHY OF THE RECORD SET IN 2012. LITTLE CHANGE IN THE SHORT TERM AS THE JET STREAM MOVES OVERHEAD FROM THE SW ALLOWING HIGH CLOUDS TO CONTINUE OFF AND ON THROUGH TOMORROW NIGHT. H7 WINDS REMAIN OUT OF THE SW ALLOWING WARM TEMPS TO CONTINUE. .LONG TERM...(TUESDAY THROUGH SUNDAY) ISSUED AT 255 PM MST SUN NOV 30 2014 HEIGHTS RISE ON TUE AS A WEAK RIDGE MOVES OVER THE AREA. BY TUE AFTERNOON THE NEXT FEATURE OF INTEREST...IN THE FORM OF A CLOSED LOW TAKES AIM AT THE CENTRAL TO NORTHERN CALIFORNIA COAST. THERE HAS BEEN MUCH ANTICIPATION AS WE HAVE WATCHED THIS SYSTEM FOR THE PAST SEVERAL SEVERAL DAYS. THE MODELS AGREE THAT THIS LOW WILL WEAKEN AND BECOME QUITE DISORGANIZED AS IT MOVES ONSHORE...WITH A SERIES OF WEAK WAVES GETTING CAUGHT UP IN THE WESTERLY FLOW ACROSS THE GREAT BASIN AND EASTWARD. COMPARED TO THE ECMWF...THE GFS HAD INITIALLY SHOWN BETTER RUN-TO-RUN CONSISTENCY WITH A STRONGER/WETTER SOLUTION FOR OUR FORECAST AREA. HOWEVER THE LAST FEW RUNS HAVE REVERSED THIS TREND WITH THE GFS TRENDING WEAKER/DRIER WITH EACH RUN. THE EC NOW LOOKS MORE LIKE THE EARLIER GFS...BUT NOT AS ORGANIZED. THE NAM12 SUPPORTS THE EC...EXCEPT IT SHOWS THE BEST QPF FIELD SHIFTED NORTH AND ACROSS THE CENTRAL PORTION OF THE FORECAST AREA INSTEAD OF OVER THE SAN JUANS. SO UNCERTAINTY PERSISTS IN JUST WHERE AND HOW MUCH PRECIPITATION OUR FORECAST AREA WILL RECEIVE. FOR THIS FORECAST HAVE GENERALLY FOLLOWED THE ECMWF...TAKING INTO ACCOUNT THE QPF SPREAD IN THE NAM12...AND TO A LESSER DEGREE THE BACK-PEDALING OF THE GFS. ALL MODELS AGREE THAT A WARM...MOIST AIR MASS ORIGINATING IN THE SUB-TROPICS WILL STREAM UP FROM THE SOUTHWEST TUE EVENING AHEAD OF THE LOW. THE EC...SUPPORTED BY THE EARLIER TRENDS...SHOW THIS FETCH MOVING OVER THE FOUR CORNERS AREA TUE NIGHT...INTO EARLY WED. GOOD UPGLIDE ON ISENTROPIC SURFACES WILL SPREAD IN DURING THE EVENING AND CONTINUE INTO THE MORNING BEFORE THE FIRST WAVE PASSES OVER THE AREA ON WED. THIS ALONG WITH FAVORABLE BUT MODEST OROGRAPHICS WILL RESULT IN PRECIPITATION DEVELOPING OVER THE SOUTHWEST TO FAR WESTERN EDGE OVERNIGHT...THEN SPREADING ACROSS THE AREA ON WED. THE FLOW WILL REMAIN ENERGETIC AND MOIST ENOUGH FOR CONTINUED SNOW IN THE COLORADO MOUNTAINS WED NIGHT ...DIMINISHING ON THURSDAY. WITH THE TENDENCY FOR THIS SYSTEM TO WEAKEN AND BREAK APART...HAVE GENERALLY KEPT AMOUNTS ON THE LOW SIDE. ALSO OF CONCERN IS ITS WARM NATURE. SNOW LEVELS ARE BOUND TO BE ON THE HIGH SIDE WITH RAIN IN ALL BUT THE HIGHER VALLEYS WHERE A RAIN/SNOW MIX WILL BE POSSIBLE. 700MB TEMPS RANGE FROM +1C SOUTH TO -1C NORTH THROUGH WED...ONLY COOLING A LITTLE OVERNIGHT. BUT I EXPECT DIABATIC COOLING FROM MELTING...AND NOCTURNAL EFFECTS WILL BRING SNOW SOMEWHAT LOWER. THEREFORE A FEW INCHES OF SNOW WILL BE POSSIBLE OVER THE HIGHER MOUNTAINS BY EARLY THU. THIS SNOW WILL GENERALLY BE ON THE WET SIDE WITH THE POTENTIAL OF MOUNTAIN ROADWAYS BECOMING SLOPPY AND SLUSHY AT TIMES. TODAYS 12Z GFS MODEL RUN HAS NOW COME INTO BETTER AGREEMENT WITH THE ECMWF THROUGH THE REMAINDER OF THE LONG TERM PERIOD. MODELS SHOW THE THE NEXT DISTURBANCE WILL IMPACT THE AREA DURING THE WEEKEND AS A SOUTHERN BRANCH WAVE PASSES OVER THE REGION. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY EVENING) ISSUED AT 938 PM MST SUN NOV 30 2014 A PASSING DISTURBANCE TONIGHT WILL PRODUCE -SN MAINLY OVER THE CO NORHTERN-CENTRAL MTNS. MTN TOP OBSCURATIONS EXPECTED FROM 06-15Z FOR THE CO MOUNTAINS FROM THE WYOMING BORDER TO THE HIGHWAY 50 CORRIDOR. KHDN KSBS KEGE KASE COULD ALL SEE SOME LIGHT SNOW 06-12Z TONIGHT BRINGING CIGS BLO 050 AND VSBY BLO 5SM. THEN VFR CONDITIONS WILL DOMINATE ON MONDAY. && .GJT WATCHES/WARNINGS/ADVISORIES... CO...NONE.
