The episode as NWS PUB wrote it up.
The combination of arctic air and a strong Pacific disturbance caused snow...heavy at times...to impact portions of the I-25 corridor and Arkansas Valley. Some of the higher snow totals include 6 to 8 inches near Pueblo West (Pueblo County) and around Penrose...Florence...and Canon City (Fremont County)...9 inches in the vicinity of Beulah and 12 inches near Rye (Pueblo 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 9, 6:11 AM MST, 8 hours 49 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PUEBLO CO 611 AM MST SUN JAN 9 2011 .SHORT TERM... (TODAY AND TONIGHT) ...ARCTIC FRONT MOVES THROUGH THE SOUTHEAST PLAINS TODAY WITH SNOW DEVELOPING AND BECOMING WIDESPREAD... THE FOCUS CONTINUES TO BE ON THE DEVELOPING WINTER WEATHER SITUATION. CURRENT SATELLITE IMAGERY AND SURFACE OBSERVATIONS SHOW MID AND HIGH CLOUDS ACROSS MUCH OF EASTERN COLORADO WHILE SNOW IS SPREADING OVER THE WESTERN SLOPE AND CONTINENTAL DIVIDE. SOME LOW CLOUDS AND LIGHT FREEZING PRECIPITATION HAS BEEN REPORTED EARLY THIS MORNING IN KDEN AND KLIC. FARTHER SOUTH IN OUR CWA...CIGS HAVE CONTINUED TO BE MID AND HIGH LEVEL CLOUDS PRIMARILY. 06Z RUNS OF THE GFS AND NAM IN FAIRLY GOOD AGREEMENT WITH TIMING OF FRONTAL PASSAGE...SNOW DEVELOPMENT AND NOW SNOW AMOUNTS. FRONT ARRIVES IN THE NORTHERN PORTION OF THE CWA AROUND 12Z AND THEN MOVES THROUGH THE REMAINDER OF THE PLAINS THROUGH 21Z BEFORE BECOMING BANKED UP AGAINST THE SOUTHEAST CO MOUNTAINS. LATEST MODEL TRENDS ARE PLACING THE HEAVIEST SNOW AMOUNTS IN WESTERN PUEBLO... HUERFANO...CUSTER AND FREMONT COUNTIES. MODELS SHOW UP TO 10 INCHES IN PORTIONS OF THIS AREA. THE LATEST MODEL RUN SNOW AMOUNTS ARE NOT AS BULLISH FOR TELLER AND NORTHERN EL PASO COUNTIES. SNOW TO LIQUID RATIOS WILL BE ON THE HIGH SIDE WITH 30 TO 1 RATIOS POSSIBLE. DESPITE THE MODEL FOCUSING HEAVIES SNOW FARTHER SOUTH...STILL BELIEVE THAT SNOWFALL AMOUNTS IN TELLER AND NORTHERN EL PASO COUNTIES WILL BE SIGNIFICANT AND HAVE NOT CHANGED ANY OF THE CURRENT WINTER STORM HIGHLIGHTS PRIOR TO THE ONSET OF THE PRECIPITATION. LATER SHIFTS WILL HAVE TO MONITOR THE DEVELOPMENTS AS THE PRECIPITATION BEGINS. NOT AS CONFIDENT IN THE DEVELOPMENT OF WIDESPREAD FREEZING DRIZZLE ON THE EASTERN PLAINS. LATEST NAM FORECAST SOUNDINGS ARE LESS FAVORABLE FOR FREEZING DRIZZLE. CURRENT THINKING IS THAT ANY FREEZING DRIZZLE THAT DEVELOPS WILL BE PATCHY AND NOT LAST LONG BEFORE THE FRONT MOVES IN AND THE COLUMN SATURATES AND SNOW DEVELOPS. SNOW WILL CONTINUE THIS EVENING AND HEAVIEST PRECIPITATION WILL BE FOCUSED IN AND NEAR THE WET MOUNTAINS DURING THE EVENING HOURS. SHOULD SEE SNOW BEGIN TO TAPER OFF OVER PARTS OF THE PLAINS DURING THE EARLY MORNING MONDAY. IN ANY CASE...THIS LOOKS LIKE THE BIGGEST SNOWFALL EVENT OF THE SEASON FOR THE SOUTHEAST CO MOUNTAINS AS MOST OF THE SNOW HAS FALLEN IN THE CONT DIVIDE AND CENTRAL CO MOUNTAINS IN PREVIOUS EVENTS. TEMPERATURES WILL BE RATHER DIFFICULT THROUGH THE PERIOD. EARLY MORNING TEMPERATURES REMAINED FAIRLY MILD IN THE 20S AND LOWER 30S AT THE LOWER ELEVATIONS. DEWPOINTS WERE IN THE TEENS AND 20S ACROSS THE CWA. HAVE FORECAST HIGHS IN THE LOWER 40S FOR AREAS IN AND NEAR THE SOUTHEAST COLORADO MOUNTAINS THIS AFTERNOON WITH STEADY OR FALLING TEMPERATURES ON THE PLAINS. OVERNIGHT LOWS WILL BE IN THE SINGLE DIGITS AND LOWER TEENS. STARK .LONG TERM... (MONDAY THROUGH SATURDAY) PRIMARY LONGER TERM METEOROLOGICAL ISSUES INCLUDE AMOUNT OF ADDITIONAL SNOW MONDAY AS WELL AS UNSEASONABLY COLD TEMPERATURES FROM MONDAY INTO WEDNESDAY WITH WIND CHILLS POTENTIALLY BECOMING AN ISSUE BOTH MONDAY NIGHT AND TUESDAY NIGHT. HEAVIEST SNOW EVENT SO FAR THIS COOL SEASON OF 2010/2011 OVER THE EASTERN SLOPES OF THE EASTERN MOUNTAINS(ESPECIALLY THE WET MOUNTAINS) WILL BE ONGOING MONDAY(ESPECIALLY MONDAY MORNING) WITH AT LEAST A FEW ADDITIONAL INCHES OF SNOW ANTICIPATED OVER THE EASTERN SLOPES...PRIMARILY DURING THE MORNING HOURS. HAVE ALSO CONTINUED TO DEPICT ADDITIONAL ACCUMULATING SNOW OVER LARGE SECTIONS OF THE CWFA MONDAY(ESPECIALLY EASTERN SECTIONS)...ONCE AGAIN WITH THE HIGHEST POTENTIAL FOR ACCUMULATING SNOW ANTICIPATED DURING MONDAY MORNING. IT APPEARS THAT SNOW RATIOS WILL HIT OR EXCEED 20 TO 1 VALUES WITH THIS EVENT AND THE POTENTIAL STILL EXISTS THAT SOME OF THE WINTER WEATHER ADVISORIES MAY NEED TO BE UPGRADED AND POSSIBLY EXTENDED(ESPECIALLY OVER PORTIONS OF ZONES 87/88/95/96/97 AND 98 AND POSSIBLY EVEN PORTIONS OF ZONES 85 AND 86) DUE TO THE PROJECTED HIGH SNOW RATIOS AND FAVORABLE UPPER SUPPORT AS DEPICTED BY LATEST PV TRENDS. WFO PUEBLO WILL CONTINUE TO MONITOR CLOSELY. HAVE ALSO PAINTED LATEST GRIDS/ZONES(ESPECIALLY EASTERN SECTIONS) WITH BLOWING SNOW AT TIMES FROM MONDAY INTO MONDAY NIGHT. AS SNOW ENDS OVER CWFA LATER MONDAY/MONDAY NIGHT...FOCUS SHIFTS TO UNSEASONABLY COLD EARLY TO MID JANUARY TEMPERATURES...ESPECIALLY FROM MONDAY INTO WEDNESDAY MORNING WITH PROJECTED MAXIMUM TEMPERATURES ON MONDAY AND TUESDAY STRUGGLING TO REACH THE UPPER SINGLE DIGITS AND TEENS OVER THE I-25 CORRIDOR AND SOUTHEASTERN COLORADO PLAINS SECTOR. PROJECTED MINIMUM TEMPERATURES FOR BOTH MONDAY NIGHT AND TUESDAY NIGHT SHOULD RUN IN THE 0 TO -20F RANGE CWFA-WIDE AND ALTHOUGH SURFACE WINDS ARE EXPECTED TO BE ON THE LIGHTER SIDE...WIND CHILLS MAY BECOME AN ISSUE BOTH MONDAY NIGHT AND TUESDAY NIGHT IF THESE COLD SURFACE TEMPERATURES ARE REALIZED. WFO PUEBLO WILL CONTINUE TO MONITOR CLOSELY. FOR THE REMAINDER OF THE LONGER TERM(WEDNESDAY INTO NEXT SUNDAY) HAVE PAINTED ISOLATED TO SCATTERED POPS AT TIMES OVER THE CENTRAL AND WESTERN MOUNTAINS WITH NIL TO LOW-GRADE POPS ELSEWHERE. IN ADDITION...MODERATING TEMPERATURES ARE ANTICIPATED FROM LATER WEDNESDAY INTO NEXT SATURDAY. && .AVIATION... AN ARCTIC FRONT WILL MOVE SOUTH THROUGH THE SOUTHEAST COLORADO PLAINS TODAY. THE FRONT IS EXPECTED TO MOVE THROUGH EL PASO COUNTY BETWEEN 12Z AND 15Z AND CONTINUE SOUTHWARD TO THE SOUTHERN BORDER OF CO BY 21Z. SNOW WILL DEVELOP ACROSS THE PLAINS IN THE NORTHEAST TO EASTERLY UPSLOPE SURFACE WINDS. IN THE MOUNTAINS...SNOW WILL CONTINUE ACROSS THE CONTINENTAL DIVIDE WITH CONTINUING WIDESPREAD MVFR AND LIFR CONDITIONS. EXPECT CONDITIONS TO DETERIORATE TO WIDESPREAD MVFR TO LIFR BEHIND THE FRONT ON THE PLAINS. STARK && .PUB WATCHES/WARNINGS/ADVISORIES...
