The episode as NWS PUB wrote it up.
A slow moving weather system brought a prolonged period of snow to the southern mountains of Colorado. Because of the long duration of the event...no warning was necessary. Over one foot of snow fell on Wolf Creek Pass in Mineral County...and from 6 to 14 inches fell from La Veta to Cuchara in Huerfano County.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pueblo, CO wrote its last area forecast discussion before the first event at Jan 30, 3:05 PM MST, 6 hours 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 305 PM MST TUE JAN 30 2007 .SHORT TERM... (TONIGHT AND WEDNESDAY) SHORT TERM CONCERNS ARE TEMPERATURES ALONG WITH SNOW CHANCES AND AMOUNTS. CURRENT WATER VAPOR IMAGERY AND RUC UPPER AIR ANALYSIS INDICATING WEST TO NORTHWEST FLOW ALOFT ACROSS THE STATE WITH ONE WEAK SHORT WAVE SHEARING APART AS IT DIVES ACROSS THE GREAT BASIN AS ANOTHER STRONGER SYSTEM CONTINUES TO DIVE OUT OF CENTRAL CANADA AND ACROSS THE NORTHERN ROCKIES ATTM. WATER VAPOR ALSO INDICATING SUBTROPICAL MOISTURE STREAMING ACROSS THE DESERT SOUTHWEST AHEAD OF OLD UPPER LOW ACROSS THE NORTHERN BAJA REGION. MODELS IN FAIR AGREEMENT WITH WEATHER DETAILS WITH INCREASING WESTERLY FLOW ALOFT ACROSS THE STATE TONIGHT AS CENTRAL CANADIAN SYSTEM AND ASSOCIATED 100+ KT JET CORE DIVES ACROSS THE NORTHERN GREAT BASIN CARVING OUT A BROAD TROUGH ACROSS THE NORTHERN ROCKIES TONIGHT. THE BROAD TROUGH ALOFT CONTINUES TO SLOWLY MOVE ACROSS THE STATE THROUGH THE DAY ON WEDNESDAY...WITH TROUGH AXIS PROGGED ACROSS CENTRAL COLORADO AT 00Z THU. FOR TONIGHT...INCREASING MOISTURE AND WEST TO SOUTHWEST FLOW PROGGED ACROSS THE CENTRAL AND SOUTHWEST MTS THROUGH THE OVERNIGHT PERIOD WITH BEST MOISTURE ACROSS THE EASTERN SAN JUAN MTS AND SOUTHERN TIER ZONES WITH PROXIMITY TO SUBTROPICAL PLUME. OROGRAPHIC SNOW MODEL YIELDING BETWEEN 2-4 INCHES ACROSS THE EASTERN SAN JUAN MTS OVERNIGHT AND ANOTHER 3-6 INCHES ON WEDNESDAY WITH INCREASING ASCENT AHEAD OF BROAD TROUGH...HAVE ISSUED A SNOW ADVISORY FROM 06Z WED THROUGH 06Z THU FOR ZONES 66 AND 68. LIGHT SNOW EXPECTED TO DEVELOP LATE TONIGHT ACROSS THE CENTRAL MTS AS WELL WITH INCREASING WESTERLY FLOW...THOUGH AMOUNTS TO REMAIN BELOW ADVISORY CRITERIA AT LEAST UNTIL LATER WEDNESDAY. OVERNIGHT LOWS TO REMAIN A CHALLENGE WITH DEVELOPING LEE TROUGHING ACROSS THE PLAINS AND SOME INCREASING HIGH CLOUDS TO HELP KEEP TEMPS UP...HOWEVER DO BELIEVE THERE WILL BE A WINDOW THIS EVENING WHERE COLD AND SNOW COVERED AREAS ACROSS THE LOWER ARKANSAS AND SAN LUIS VALLEY WILL TANK BEFORE STEADYING OUT OR WARMING INTO THE EARLY MORNING. WEDNESDAY...PASSING TROUGH SENDS ANOTHER FRONT AND RE-ENFORCING SURGE OF COLD AIR ACROSS EASTERN COLORADO EARLY WEDNESDAY MORNING...WITH FRONT MOVING ACROSS THE PALMER DVD BETWEEN 15Z AND 17Z AND ACROSS THE REST OF THE PLAINS BY EARLY AFTERNOON. WITH LIFT AND MOISTURE INCREASING ACROSS THE REGION AHEAD OF TROUGH AXIS HAVE GONE WITH LIKELY POPS ACROSS MOST OF THE HIGHER TERRAIN AND IMMEDIATE ADJACENT PLAINS AND MAINLY CHANCE POPS ACROSS THE FAR EASTERN PLAINS. MODEL CROSS SECTIONS INDICATING GOOD DENDRITIC GROWTH POTENTIAL WITH TEMPS BETWEEN -14C AND -20C WITHIN THE MOIST LAYER...WITH LATER SHIFTS POSSIBLY HOISTING HIGHLIGHTS ACROSS THE CENTRAL AND EASTERN MTS WITH SNOW ACCUMS BETWEEN 4-8 INCHES POSSIBLE. WITH THE FRONT MOVING ACROSS THE PLAINS IN THE MORNING WILL LIKELY SEE HIGHS BY THE LATE MORNING WITH DECREASING TEMPERATURES THROUGH THE AFTERNOON. -MW .LONG TERM... (WED NIGHT THROUGH TUE) ...WINTRY WEATHER WILL CONTINUE THROUGH AT LEAST SUN... ...PREPARE NOW FOR EXTREMELY COLD TEMPERATURES FRI-WEEKEND... WED NIGHT AND THU...THE COMBINATION OF A LONGWAVE TROUGH AND YET ANOTHER COLD FRONTAL SURGE SHOULD BRING THE POTENTIAL FOR FLUFFY SNOWFALL AND COLD TEMPERATURES. H7 TEMPERATURES ARE FORECAST TO RANGE FROM -12C TO -15C. SHOULD SEE PLENTY OF SYNOPTIC SCALE ASCENT TO SQUEEZE OUT SNOWFLAKES FROM THE CLOUD COVER. COULD SEE ANOTHER 3-5 INCHES OVER THE MOUNTAINS AND 1-3 INCHES ACROSS THE LOWER ELEVATIONS OF SOUTH CENTRAL AND SOUTHEAST CO. MIGHT NEED AN ADVISORY FOR OUR EASTERN CO MOUNTAINS AND ADJACENT I-25 CORRIDOR THROUGH WED EVENING...IF THE POTENTIAL SNOW EVENT STILL LOOKS GOOD. IT APPEARS THE PRECIPITATION POTENTIAL SHOULD DIMINISH LATE WED NIGHT AND COULD PICKUP AGAIN AROUND THE CONTINENTAL DIVIDE THU AFTERNOON. THERE COULD BE A BRIEF RESPITE OF THE FLUFFY SNOW POTENTIAL ON THU UNTIL THE NEXT WEATHER SYSTEM TAKES AIM FOR THU NIGHT THROUGH FRI NIGHT. I HAVE INCREASE POPS TO CATEGORICAL ACROSS THE SOUTHWEST MOUNTAINS HIGHER TERRAIN WED EVENING GIVEN THE SNOW ADVISORY. ALSO...INCREASED POPS TO HIGH CHANCE AND LIKELY FOR THE REMAINDER OF THE MOUNTAINS AND I-25 CORRIDOR FOR WED EVENING. DECREASED OR REMOVED POPS FOR THU...BUT MAINTAINED SOME LOW POPS AROUND THE CONTINENTAL DIVIDE. FRI THROUGH SUN...DEEP LONGWAVE TROUGH EXTENDS FROM THE POLAR LOW OVER CENTRAL CANADA INTO THE CENTRAL ROCKIES. THERE HAS BEEN RELATIVELY GOOD CONSISTENCY ON THIS PATTERN DEVELOPING FOR LATE THIS WEEK INTO THE WEEKEND. FOLLOWED THE 06Z/30 DGEX GIVEN THE FINER TERRAIN RESOLUTION. H7 TEMPERATURES ARE PROGGED TO RANGE FROM -18C TO -28C FRI AND SLIGHTLY WARMING THROUGH THE WEEKEND. HIGH AND LOW TEMPERATURES WILL LIKELY BE IN THE SUB-ZERO VALUES FOR OUR MOUNTAINS AND HIGH VALLEYS THROUGH THE WEEKEND. ALSO...THE SOUTHEAST CO PLAINS WILL RANGE FROM SUB-ZERO VALUES INTO THE TEENS. FRI COULD BE A BRUTAL DAY. GIVEN THE POTENTIAL SYNOPTIC ASCENT AND THERMAL STRUCTURE PROJECTED FOR FRI-SAT...HIGH SNOW RATIOS WILL BE LIKELY 20-1 TO 40-1...SO JUST A MINUTE AMOUNT OF QPF COULD PRODUCE 1-6 INCHES OF FLUFFY SNOW. INCREASED POPS TO HIGH CHANCE FOR THE MOUNTAINS AND I-25 CORRIDOR ON FRI...AND CONTINUED SLIGHT CHANCE TO NO MENTION OVER THE WEEKEND. WHILE WIND SPEEDS WILL NOT BE ALL THAT STRONG...IT WILL NOT TAKE MUCH WIND SPEED TO DROP THE WIND CHILL VALUES GIVEN THE EXTREMELY COLD TEMPERATURES. WIND CHILL READINGS OF -25F TO -35F IN THE MOUNTAINS AND -20F TO 0F WILL BE COMMON FRI THROUGH THE WEEKEND. MON AND TUE...MEDIUM RANGE MODELS PROJECTING NORTHWEST FLOW TO DEVELOP OVER THE ROCKIES AS THE EXTREMELY COLD LONGWAVE TROUGH MIGRATES EASTWARD. A BIG CHALLENGE IF AND WHEN THE MODIFIED ARCTIC AIR MASS WILL RECEDE ACROSS EASTERN CO. AGAIN...FOLLOWED THE 06Z/30 DGEX FINER TERRAIN RESOLUTION MODULE. WILL PLAY A MODERATING TEMPERATURE TREND...EXCEPT FOR THE LOWER AR RIVER VALLEY IN EXTREME SOUTHEAST CO GIVEN THE 1-2 FEET OF SNOW PACK...AND POSSIBLY MORE...THAT WILL BE OVER THIS AREA. MOS/HPC GUIDANCE HAS BEEN 10-20 DEGREES TOO WARM IN THESE DENSE SNOW PACK AREAS. IT HAS BEEN SEVERAL WEEKS SINCE KLAA WAS 35F OR GREATER...SO WILL KEEP TEMPERATURES ON THE COLD SIDE UNTIL THEY REACH ABOVE 35F. METZE && .PUB WATCHES/WARNINGS/ADVISORIES... SNOW ADVISORY FROM 11 PM THIS EVENING TO 11 PM MST WEDNESDAY FOR COZ066-068. && 23/17
