NWS Pueblo, CO wrote its last area forecast discussion before the first event at Dec 29, 5:27 AM MST, 2 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 527 AM MST WED DEC 29 2010 .SHORT TERM... (TODAY AND TONIGHT) ...MAIN SHORT TERM CONCERNS INCLUDE DAMAGING WIND POTENTIAL ACROSS THE SOUTHERN MTS AND ADJACENT PLAINS...ALONG WITH DEVELOPING SNOWFALL AND AMOUNTS ALONG THE CONTDVD... CURRENT WATER VAPOR IMAGERY AND RUC UPPER AIR ANALYSIS INDICATING INCREASING WEST TO SOUTHWEST FLOW ALOFT ACROSS THE REGION AS A STRONG 120 KT JET CORE DIVING SOUTH ACROSS THE PAC NW COAST CONTINUES TO CARVE OUT A BROAD UPPER TROUGH ACROSS THE WEST COAST ATTM. WATER VAPOR IMAGERY ALSO INDICATING AMPLE MID AND UPPER LEVEL MOISTURE STREAMING AHEAD OF DEVELOPING SYSTEM ACROSS THE GREAT BASIN AND INTO WESTERN COLORADO ATTM. MODELS IN DECENT AGREEMENT THROUGH THIS PERIOD WITH BROAD UPPER TROUGH CONTINUE TO DIG ACROSS THE WEST COAST INTO THE AFTERNOON WITH A BROAD TROUGH AXIS ACROSS THE EASTERN GREAT BASIN REGION AS STRONG JET CORE ROUNDS BASE OF TROUGH AND TRANSLATES ACROSS SOUTHERN COLORADO BY 12Z THU. INCREASING SW FLOW ALOFT STRENGTHENS LEE TROUGHING ACROSS THE I-25 CORRIDOR THROUGH THE AFTERNOON. LATEST HIGH RESOLUTION NAM AND LOCAL WRF MODELS CONTINUING TO INDICATE STRONG DOWNSLOPE WIND POTENTIAL ACROSS THE SOUTHERN MTS AND IMMEDIATE ADJACENT PLAINS LATE THIS MORNING THROUGH THE EARLY EVENING WITH WSW 50-60KT H7 WINDS...ALONG WITH A STRONG MT TOP STABLE LAYER AND GOOD REVERSE SHEAR PROFILE TO AROUND H5 ALL SUPPORTING DAMAGING WIND GUSTS OF 60 TO 80 MPH. WITH THAT SAID...HAVE UPGRADED HIGH WIND WATCH ACROSS THE SANGRE DE CRISTO MTS AND HIGHER TERRAIN ALONG AND WEST OF THE SOUTHERN I-25 CORRIDOR...THOUGH HAVE DELAYED START AND END TIME TO 18Z THROUGH 03Z WHEN INCREASING SHEAR ALOFT LOOKS TO BREAK MT WAVE. MODELS CONTINUE TO INDICATE GOOD MOISTURE EMBEDDED WITHIN THE INCREASING WSW OROGRAPHIC FLOW FOR GENERALLY LIGHT SNOW TO DEVELOP ACROSS THE HIGHER TERRAIN ALONG AND WEST OF THE CONTDVD THIS MORNING...WITH SNOWFALL INCREASING IN COVERAGE AND INTENSITY LATE THIS AFTERNOON AND TONIGHT WITH INCREASING LAPSE RATES AND UVV AHEAD BROAD UPPER TROUGH. PREVIOUS SHIFT ISSUED WINTER STORM WARNINGS AND ADVISORIES BEGINNING AT 18Z WHICH STILL LOOKS ON TRACK WITH UP TO A FOOT OF SNOW POSSIBLE ACROSS THE EASTERN SAN JUAN MTS AND LESS AMOUNTS FURTHER NORTH ACROSS THE LA GARITAS AND SAWATCH MTS THROUGH TONIGHT. FURTHER EAST...LEE TROUGHING...INCREASING LAPSE RATES SUPPORTING GOOD MIXING...AND WARMING ALOFT THROUGH MORNING WILL HELP BOOST TEMPS HIGHS INTO THE UPPER 40S TO UPPER 50S ACROSS THE EASTERN PLAINS THIS AFTERNOON...THOUGH WILL LIKELY NOT FEEL AS WARM WITH INCREASING MID AND HIGH LEVEL CLOUDS. GUSTY WSW WINDS OF 15 TO 30 MPH CAN BE EXPECTED THROUGH INTO THE AFTERNOON...WITH THE STRONGEST WINDS ALONG AND WEST OF THE I-25 CORRIDOR. THE GUSTY WINDS WILL INCREASE FIRE DANGER ACROSS THE PLAINS...HOWEVER...RHS LOOK TO REMAIN IN THE UPPER TEENS AND 20S AND WILL NOT ISSUE ANY FIRE WEATHER HIGHLIGHTS ATTM. CLOUDS AND BREEZY WINDS TO CONTINUE ACROSS THE EASTERN PLAINS INTO THE EVENING AS LEE TROUGH KICKS OUT ACROSS THE FAR SE PLAINS KEEPING OVERNIGHT LOWS UP ACROSS THE PLAINS DESPITE COOLING ALOFT WITH APPROACHING TROUGH. -MW .LONG TERM... (THURSDAY THROUGH TUESDAY) STILL SOME SIGNIFICANT DIFFERENCES WITH TRACK AND STRENGTH OF THE UPPER LOW LEADING TO HIGH FORECAST UNCERTAINTIES FOR SNOWFALL TOTALS...ESPECIALLY ACROSS THE SOUTHEAST MOUNTAINS AND PLAINS FOR THURSDAY THROUGH FRIDAY MORNING. 00Z GFS RUN HAS TRENDED FARTHER SOUTH...AND WAS THE FARTHEST SOUTH OF ALL THE 00Z MODELS IN TRACKING THE UPPER LOW INTO FAR SE CO BY 12Z FRI...BEFORE LIFTING IT TO THE NORTHEAST FRI AFTN. THIS TRACK IS STILL ON THE FASTER AND MORE SOUTHERN SIDE OF THE GFS ENSEMBLE MEAN. ECMWF AGREES WELL WITH THE GFS ENSEMBLE MEAN. AND NAM IS FARTHER NORTH AND SLOWER IN BRINGING THE TROF ACROSS TUES NIGHT. THUS...THE GFS (ESPECIALLY THE 06Z RUN) PORTRAYS THE WETTEST SOLUTION FOR THE SOUTHEAST MTS AND PLAINS...WITH ANYWHERE FROM 2-10 INCHES OF SNOW...WITH THE HEAVIEST ACROSS TELLER AND EL PASO COUNTIES...AND POINTS NORTHEASTWARD. THE NAM AND HAS ON THE ORDER OF A TRACE TO 4 INCHES...AND THE ECMWF QPF SUGGESTS SNOW AMOUNTS MORE IN THE 2-5 INCH RANGE. HAVE GENERALLY DISCOUNTED THE FARTHER SOUTH GFS RUN...AS THIS IS A DEPARTURE FROM THE PREVIOUS RUNS AND THE OUTLIER. THE NAM12 IS ON THE SLOWEST AND DRIEST SIDE OF THE SPECTRUM...SO AS MUCH AS POSSIBLE HAVE LEANED THE FORECAST HEAVILY ON THE GFS ENSEMBLE MEAN AND THE ECMWF RUN. FOR SENSIBLE WEATHER...THIS WILL MEAN HEAVY SNOW CONTINUING ALONG THE CONTINENTAL DIVIDE ON THURS...WITH THE HEAVIEST FALLING ACROSS THE EASTERN SAN JUAN MOUNTAINS WHERE SW FLOW PROVIDES THE BEST OROGRAPHIC COMPONENT. STILL LOOKING AT TOTAL SNOWFALL AMOUNTS IN THE 1-2 F00T RANGE...WITH LOCALLY HIGHER AMOUNTS ALONG THE SOUTHWEST FACING SLOPES. ALTHOUGH SOUTHWEST FLOW IS NOT ALL THAT FAVORABLE...UPPER FORCING ASSOC WITH UPPER LOW...STEEPENING LAPSE RATES AND CAA SHOULD RESULT IN SOME MODERATE TO HEAVY SNOWFALL AT TIMES ACROSS THE REMAINDER OF THE CENTRAL AND SOUTHWEST MOUNTAINS. SATURATION IN THE -12 TO -18C DENDRITIC GROWTH ZONE SHOULD ALLOW FOR AROUND 10-16 INCHES OF FLUFFY SNOW ACROSS THE HIGHER SAWATCH RANGE...AND GENERALLY 6-12 INCHES FOR THE LA GARITAS...THE UPPER RIO GRANDE...AND THE CENTRAL AND EASTERN PORTIONS OF LAKE COUNTY. GOING HIGHLIGHTS STILL LOOK GOOD...AND HAVE SPREAD THEN ACROSS LAKE COUNTY AND THE LOWER ELEVATIONS OF THE SAWATCH RANGE WHERE GRIDS ARE YIELDING 6 TO 12 INCHES OF SNOW BY EARLY FRIDAY MORNING. FOR THE SOUTHEAST PLAINS...ONE MORE WARM DAY EXPECTED ON THURS...THOUGH THERE ARE MODEL DIFFERENCES WITH THE TIMING OF THE COLD FRONT. GFS WOULD SUGGEST A FASTER FROPA FOR COLORADO SPRINGS...WITH TEMPS TOPPING OUT AROUND NOON BEFORE FALLING AS THE FRONT PASSES AND SNOW SPREADS IN. NAM KEEPS THE FRONT ALONG THE PALMER DIVIDE BEFORE DROPPING IT SOUTH INTO KCOS BY 00Z. HAVE KEPT FORECAST ON THE WARMER SIDE OF GUIDANCE FOR THE SE PLAINS FOR NOW. BY THURS NIGHT...FRONT DROPS THROUGH THE PLAINS AND SHOULD SEE SNOW SPREAD SOUTHWARD DURING THE LATE AFTERNOON THROUGH THE OVERNIGHT HOURS. GFS...WITH ITS STRONGER AND FARTHER SOUTH POSITION OF THE UPPER LOW...HAS A PERIOD OF STRONGER ISENTROPIC UPGLIDE AND NE UPSLOPE FLOW...AND HENCE HEAVIER SNOWFALL AMOUNTS. THE NAM...WITH ITS LESS CONSOLIDATED UPPER LOW...IS WEAKER...BUT DOES SUGGEST A PERIOD OF LIGHT SNOW THURS NIGHT/EARLY FRI BEHIND THE FRONT. WITH STEEP LAPSE RATES...AND SATURATION THROUGH THE FAVORABLE DENDRITIC GROWTH ZONE...COULD MORE EASILY GET A FEW INCHES OF FLUFF ACROSS THE SOUTHEAST MTS AND PLAINS. FOR NOW...FAVORED MODEL CONSENSUS (ECMWF...UKMET...NAM...GFS ENSEMBLE MEAN) SEEM TO POINT TO THE HEAVIER AMOUNTS ACROSS NORTHEAST CO...WITH SE CO REMAINING ON THE SRN FRINGES OF THE STORM TRACK. THUS...WILL NOT ISSUE ANY WATCHES AT THIS POINT...BUT HAVE BUMPED UP POPS INTO THE LIKELY CATEGORY FOR THE SE MTS/ADJACENT PLAINS. WOULD NOT BE SURPRISED TO SEE ADVISORIES NEEDED AT SOME POINT FOR TELLER AND NORTHERN EL PASO COUNTIES...WHERE WE COULD SEE AROUND 3-7 INCHES OF SNOWFALL. OF COURSE...IF MODELS CONVERGE ON A MORE SOUTHERN TRACK...THEN WARNING CRITERIA SNOW AMOUNTS WILL BE POSSIBLE ACROSS THIS REGION...WITH THE POTENTIAL FOR ADVISORY SNOWFALL AMOUNTS EXTENDING FARTHER SOUTH INTO THE WET MOUNTAINS. OTHER NOTABLE SENSIBLE WEATHER WITH THIS SYSTEM WILL BE THE MUCH COLDER TEMPERATURES FOR FRIDAY AND FRIDAY NIGHT. WITH H7 TEMPS DROPPING INTO THE -15 TO -20C RANGE...SHOULD SEE HIGHS FRIDAY IN THE SINGLE DIGITS ACROSS THE MOUNTAINS...TO NEGATIVE SINGLE DIGITS ABOVE TIMBERLINE...TO TEENS ACROSS THE LOWER ELEVATIONS. AND LOW TEMPERATURES FRIDAY NIGHT/SATURDAY MORNING WILL RANGE FROM 5 BELOW TO 20 BELOW ZERO...WITH COLDEST READINGS ACROSS THE MOUNTAINS. COMBINED WITH A LIGHT NORTH WIND...WIND CHILLS COULD DIP TO AROUND 10 BELOW ZERO ACROSS PORTIONS OF THE SE PLAINS...AND TO 15 TO 25 BELOW ZERO ACROSS THE MOUNTAIN REGIONS. THIS WILL BE DRAMATIC CHANGE FROM THE ABOVE NORMAL TEMPERATURES EXPERIENCED MOST OF THIS WINTER. OTHERWISE...SNOW SHOWERS SHOULD WANE QUICKLY THROUGH THE DAY AS THE SYSTEM LIFTS OFF TO THE NORTHEAST. FOR SUNDAY AND BEYOND...DRIER NORTHWEST FLOW WILL SET IN...WITH LATEST MODEL RUNS SLOWER TO BRING NEXT ROUND OF PACIFIC ENERGY IN FROM THE WEST. BY EARLY NEXT WEEK...SHOULD SEE POTENTIAL FOR SNOW INCREASE ACROSS THE CENTRAL MTS AS SHORTWAVE TROF EVENTUALLY MOVES IN...THOUGH THERE IS QUITE A BIT OF DISCREPANCIES IN TIMING IN THE LONG RANGE MODELS. OVERALL...WILL MAINTAIN LOW ISOLATED POPS FOR THE SOUTHWEST AND CENTRAL MTS...WITH GRADUALLY MODERATING TEMPERATURES THROUGH EARLY NEXT WEEK. -KT && .AVIATION...VFR CONDITIONS EXPECTED AT TAF SITES TODAY AND TONIGHT. BREEZY TO WINDY WESTERLY WINDS STILL EXPECTED ACROSS THE MUCH OF THE AREA...WITH WSW WINDS OF 15-30 KTS AT TAF SITES THIS AFTERNOON AND EVENING. GUSTS IN EXCESS OF 60 KTS WILL BE POSSIBLE ACROSS THE SANGRE DE CRISTO MTS AND SOUTHERN I-25 CORRIDOR. SNOW WILL DEVELOP ACROSS THE CONTDVD THIS MORNING WITH CLOUDS AND SNOW OBSCURING THE MTS THIS AFTERNOON AND TONIGHT. -MW && .PUB WATCHES/WARNINGS/ADVISORIES...

THE DAMAGING WINDS WILL CONTINUE THROUGH THE EARLY EVENING BEFORE DIMINISHING INTO TONIGHT. HAZARDOUS TRAVEL CONDITIONS CAN BE EXPECTED TO DEVELOP LATER THIS MORNING...ESPECIALLY ON INTERSTATE 25 AND OTHER NORTH TO SOUTH ORIENTED ROADWAYS OF HUERFANO AND WESTERN LAS ANIMAS COUNTIES...DUE TO THE STRONG CROSSWINDS. SNOW IS EXPECTED TO DEVELOP ACROSS THE HIGHER TERRAIN ALONG AND WEST OF THE CONTINENTAL DIVIDE THIS MORNING...WITH SNOWFALL INCREASING IN COVERAGE AND INTENSITY LATE THIS AFTERNOON AND EVENING...AS A STRONG STORM SYSTEM BEGINS TO MOVE INTO THE ROCKIES. SNOW ACCUMULATIONS OF UP TO A FOOT WILL BE POSSIBLE ACROSS THE EASTERN SAN JUAN MOUNTAINS THROUGH TONIGHT...WITH 2 TO 6 INCHES OF SNOW POSSIBLE FURTHER NORTH ACROSS THE UPPER RIO GRANDE VALLEY...THE LA GARITA MOUNTAINS AS WELL AS THE HIGHER ELEVATIONS OF LAKE AND WESTERN CHAFFEE COUNTIES. HAZARDOUS TRAVEL CONDITIONS CAN ALSO BE EXPECTED TO DEVELOP LATER TODAY ACROSS HIGHER MOUNTAIN PASSES OF THE CONTINENTAL DIVIDE...ESPECIALLY WOLF CREEK PASS...DUE TO SNOW AND BLOWING SNOW. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY A STRENGTHENING LOW PRESSURE SYSTEM WILL MOVE ACROSS COLORADO THURSDAY AND THURSDAY NIGHT...WITH HEAVY SNOWFALL CONTINUING ACROSS THE SOUTHWEST AND CENTRAL MOUNTAINS. THE HEAVIEST SNOWFALL WILL OCCUR ACROSS THE EASTERN SAN JUAN MOUNTAINS...WHERE TOTAL SNOWFALL AMOUNTS WILL RANGE FROM 1 TO 2 FEET...WITH LOCAL ACCUMULATIONS OF UP TO 3 FEET ACROSS THE SOUTHWEST FACING SLOPES BY EARLY FRIDAY MORNING. SNOWFALL AMOUNTS OF 10 TO 16 INCHES WILL BE POSSIBLE ACROSS THE SAWATCH RANGE ABOVE 11000 FEET...WITH 6 TO 12 INCHES ACROSS THE LA GARITA MOUNTAINS...THE RIO GRANDE VALLEY...THE LOWER EASTERN SLOPES OF THE SAWATCH RANGE AS WELL AS CENTRAL AND EASTERN LAKE COUNTY. GUSTY SOUTHWEST TO WEST WINDS OF 15 TO 30 MPH...WITH GUSTS UP TO 40 TO 50 MPH AT TIMES WILL CAUSE AREAS OF BLOWING AND DRIFTING SNOW ACROSS THE HIGHER PEAKS AND MOUNTAIN PASSES...RESULTING IN HAZARDOUS DRIVING CONDITIONS. AS THE SYSTEM MOVES ACROSS THE COLORADO ROCKIES THURSDAY NIGHT...AN ARCTIC COLD FRONT WILL MOVE THROUGH THE REGION...SPREADING SNOW AND MUCH COLDER TEMPERATURES ACROSS THE SOUTHEAST MOUNTAINS AND PLAINS THURSDAY NIGHT THROUGH FRIDAY. THERE IS STILL QUITE A BIT OF UNCERTAINTY REGARDING THE EXACT TRACK OF THIS STORM SYSTEM AS IT MOVES THROUGH SOUTHERN COLORADO...MAKING SNOWFALL AMOUNTS ACROSS THE EASTERN MOUNTAINS AND PLAINS STILL HIGHLY UNCERTAIN AT THIS TIME. HOWEVER...IT APPEARS THE SOUTHEAST MOUNTAINS COULD SEE SOME LIGHT TO MODERATE SNOWFALL ACCUMULATIONS THURSDAY NIGHT THROUGH EARLY FRIDAY...WITH THE HEAVIEST ACCUMULATIONS POTENTIALLY FOCUSED ACROSS TELLER AND NORTHERN EL PASO COUNTIES...WHERE SNOWFALL AMOUNTS IN THE 3 TO 7 INCH RANGE WILL BE POSSIBLE. THE REMAINDER OF THE SOUTHEAST MOUNTAINS COULD SEE 2 TO 6 INCHES WITH ANYWHERE FROM A TRACE TO 2 INCHES ACROSS THE REMAINDER OF THE SOUTHEAST PLAINS. ANY SHIFT IN THE STORM TRACK TO THE NORTH OR SOUTH COULD DRAMATICALLY AFFECT THESE ANTICIPATED SNOWFALL TOTALS AND RESIDENTS OF SOUTHEAST COLORADO ARE URGED TO KEEP INFORMED OF THE LATEST FORECASTS CONCERNING THIS DEVELOPING STORM SYSTEM. SOME OF THE COLDEST TEMPERATURES EXPERIENCED YET THIS SEASON WILL IMPACT SOUTH CENTRAL AND SOUTHEAST COLORADO FRIDAY AND FRIDAY NIGHT. HIGH TEMPERATURES ON FRIDAY WILL TOP OUT IN THE TEENS ACROSS THE LOWER ELEVATIONS...WITH SINGLE DIGITS ABOVE AND BELOW ZERO ACROSS THE MOUNTAINS. BY FRIDAY NIGHT...TEMPERATURES ARE EXPECTED TO DROP BETWEEN 0 AND 20 BELOW ZERO...WITH THE COLDEST READINGS ACROSS THE MOUNTAINS AND MOUNTAIN VALLEYS. COMBINED WITH LIGHT NORTHERLY WINDS...WIND CHILLS COULD DROP TO AROUND 10 TO 15 BELOW ZERO ACROSS PORTIONS OF THE PLAINS...AND TO AROUND 25 TO 30 BELOW ACROSS THE MOUNTAINS THROUGH SATURDAY MORNING. PRECAUTIONS SHOULD BE TAKEN NOW IN PREPARATION FOR THE BITTER COLD TEMPERATURES EXPECTED TO IMPACT ALL OF THE REGION FRIDAY AND FRIDAY NIGHT. TAKE ACTION NOW TO PREVENT PIPES FROM FREEZING WHEN THE COLD AIR ARRIVES...AND IF YOU HAVE TRAVEL PLANS ACROSS SOUTH CENTRAL OR SOUTHEAST COLORADO THURSDAY THROUGH FRIDAY...KEEP INFORMED OF THE LATEST FORECASTS AND BE PREPARED FOR THE POTENTIAL FOR WINTER DRIVING CONDITIONS...PARTICULARLY IN AND NEAR THE MOUNTAINS. .SPOTTER INFORMATION STATEMENT... WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE LIKELY ACROSS THE CENTRAL AND SOUTHWEST MOUNTAINS TODAY AND TONIGHT...AND WILL BE POSSIBLE ACROSS THE SANGRE DE CRISTO MOUNTAINS AND SOUTHERN I-25 CORRIDOR THIS AFTERNOON AND EVENING. 23/31
