This snowfall event generally began on the 27th under a moist southwest flow which followed on the heels of a storm which vacated the area earlier on the same day. However, snowfall actually began for some lower elevations of northwest Colorado late on the 26th.

The episode as NWS GJT wrote it up.
This snowfall event generally began on the 27th under a moist southwest flow which followed on the heels of a storm which vacated the area earlier on the same day. However, snowfall actually began for some lower elevations of northwest Colorado late on the 26th. The potent Pacific trough which moved over the region on January 28th and 29th generally produced the greatest amount of snowfall for most areas during the five-day period which included a moist northwest flow on January 30th and 31st.
During this five day event, January 27th through January 31st, there were two significant events; one event was with the moist southwest flow and upper trough passage and the second event was the moist northwest flow. For some zones the snowfall persisted unabated through both events (COZ004-013). However, in some other zones snowfall occured during both events, though the snowfall was separated by an interlude of little or no snowfall which required two separate highlights for those zones.

ISSUED AT 452 AM MST SAT JAN 26 2013
STRONG SUBTROPICAL TAP OF MOISTURE CONTINUES TO BE TRANSPORTED INTO
THE GREAT BASIN AND ROCKIES AHEAD OF THE MAIN STORM SYSTEM MOVING
INTO THE NORTHERN BAJA REGION EARLY THIS MORNING. PWAT AT 00Z WERE
RUNNING FROM AT 200+ PERCENT OF NORMAL FROM WESTERN COLORADO DOWN TO
THE BAJA REGION AND IS AN INDICATION OF THE POTENTIAL FOR SOME
DECENT QPF OUT OF THIS FAST MOVING WAVE. MOISTURE TRANSPORT VECTORS
NEAR 300K STILL SHOWING MIXING RATIOS IN THE 5-6 G/KG RANGE MOVING
INTO OUR SOUTHERN CWA THROUGH THE AFTERNOON. THE WARM MOIST AIR
MOVING OVER THE COLDER VALLEYS IS HELPING TO PRODUCE SOME AREAS OF
LOCALLY DENSE FOG...WITH FREEZING DRIZZLE ALSO REPORTED THROUGH THE
GRAND VALLEY. THE ADVISORY WILL BE ALLOWED TO CONTINUE THROUGH
SUNRISE ATTM WITH TEMPERATURES STILL HOVERING NEAR FREEZING. RADAR
MOSAIC AND SATELLITE IMAGERY IS SHOWING THE PRECIPITATION SHIELD
APPROACHING OUR SOUTHWEST CWA EARLY THIS MORNING IN AN AREA OF
INCREASING ASCENT AHEAD OF THE APPROACHING WAVE. THIS AREA IS
EXPECTED TO REACH UP TO THE I-70 CORRIDOR THROUGH THE LATE MORNING
HOURS...SPREADING TO THE NORTHERN BORDER IN THE AFTERNOON AS THE
WEAKENING UPPER WAVE MOVES INTO CENTRAL UTAH. H7 TEMPERATURES WILL
BE APPROACHING ZERO THROUGH THE DAY IN THE WARM MOIST ADVECTION AND
SNOW LEVELS CONTINUE SOMEWHAT OF A CONCERN AND LOOK TO LIFT TO
AROUND THE 8500 FOOT LEVEL. THIS WILL LEAVE RAINFALL AGAIN TODAY FOR
MANY OF THE LOWER ELEVATIONS AND A MIX OF RAIN AND SNOW INTO THE
HIGHER VALLEYS AND MOUNTAIN BASES. NEEDLESS TO SAY THIS IS A VERY
DIFFICULT FORECAST FOR MANY REASON INCLUDED SNOW LEVELS AND
PRECIPITATION TYPE IN MANY OF THE VALLEYS. RELIED HEAVILY ON
BUFKIT SOUNDINGS FROM NAM/SREF WITH GFS KEEPING THE PBL ON THE WARM
SIDE.
OVERALL FORECAST SEEMED TO BE ON TRACK FOR HEAVY SNOW IN THE SAN
JUANS IN THE PERSISTENT MOIST SOUTHERLY FLOW IN PLACE THROUGH
SUNDAY EVENING. SNOW TOTALS HERE LOOK TO BE AROUND A FOOT IN MANY
PLACES AND MAY REACH UP TO 2 FEET. MODELS ARE IN GOOD AGREEMENT
PLACING THE MAIN AREA OF ASCENT OVER OUR SOUTHWEST CWA EARLY THIS
EVENING THEN LIFTING IT NORTHEAST INTO THE HIGH PLAINS THROUGH
SUNRISE AS THE MID LEVEL WAVE PASSES OVERHEAD. WITH THIS AREA OF
LIFT MOVING OVER THE CENTRAL MOUNTAINS IN THE SOUTHWESTERLY FLOW
THE CENTRAL MOUNTAINS WILL GET AND ADDED BOOST TO THE SNOWFALL
RATES AND DECIDED OT ADD THE FLAT TOPS RANGE TO THE ADVISORIES.
CONFIDENT FOR THE ENTIRE ZONE 10 INCLUDING ASPEN AND VAIL REMAINS
QUITE LOW AS FLOW NEVER REALLY TURNS WESTERLY. THE ELK MOUNTAINS
IN THE SOUTHERN PORTION OF THIS ZONE LOOK TO TO WELL IN THIS FLOW
BUT ON THE WHOLE IT APPEARS WIDE SPREAD ADVISORY CRITERIA SNOW IS
QUESTIONABLE SO HELD OFF. THE BIG QUESTION IN THE VALLEYS IS IF
AND WHEN THE PRECIPITATION WILL MIX WITH OR CHANGE TO SNOW...AND
WILL FREEZING PCPN BE POSSIBLE. FOR NOW IT LOOKS AS THOUGH THE
VALLEY LOCATIONS WILL REMAIN BELOW SNOW CRITERIA THOUGH PORTIONS
OF THE SOUTHERN SAN JUAN FOOTHILLS MAY RECEIVE UP AROUND 4 INCHES
BY MORNING. SOUNDINGS ALONG THE I-70 CORRIDOR SEEM TO SUPPORT RAIN
HOLDING ON FOR A WHILE THEN SWITCHING TO SNOW WITH ENOUGH COOLING
BEHIND THE WAVE TO PUSH THE WHOLE SOUNDING BELOW FREEZING.
ACCUMULATIONS IN THE VALLEYS LOOK TO REMAIN IN THE 1 TO 3 INCH
RANGE FOR NOW. SUBSIDENCE SPREADS ACROSS THE CWA IN THE WAKE OF
THE PASSING WAVE AND COOLER TEMPERATURES MOVE IN ALOFT. THIS LOOKS
TO BRING A MORE CONVECTIVE NATURE TO THE PRECIPITATION ON SUNDAY.
MUCH OF THE SHOWERS WILL BE CONFINED TO THE TERRAIN EARLY IN THE
DAY. HOWEVER MID LEVEL WINDS WILL BE BACKING TO SOUTHWEST AND
INCREASING AHEAD OF THE STRONGER TROF APPROACHING FROM THE WEST
AND THIS MAY PUSH A FEW SHOWERS IN TO THE VALLEYS. FOR NOW IT
LOOKS AS THOUGH MANY OF THE VALLEY LOCATIONS WILL WARM ENOUGH TO A
MIX TO CHANGE BACK OVER TO RAIN AS THESE SHOWERS MOVE THROUGH.
.LONG TERM...(SUNDAY NIGHT THROUGH FRIDAY)
ISSUED AT 452 AM MST SAT JAN 26 2013
BETTER CONSENSUS BETWEEN THE MEDIUM RANGE MODELS THAT BOOST
CONFIDENCE ON THE EVOLVING COLD TROUGH AND ITS PASSAGE EARLY NEXT
WEEK. THE NAM12 INSISTS THAT A CLOSED LOW CIRCULATION WOULD FORM
OVER SRN CALIFORNIA BY MONDAY AFTERNOON...THIS APPEARS TO BE THE
OUTLIER BUT CANNOT BE COMPLETELY DISCOUNTED. ALL MODEL SOLUTIONS
SUGGEST THAT ENERGY SPLITS TO SOME EXTENT AS THE UPSTREAM COLD
TROUGH DIGS TOWARD THE DESERT SOUTHWEST. THE GFS MAINTAINS ITS
IDEA OF A CONSOLIDATED TROUGH AS IT MOVES ACROSS THE CENTRAL
ROCKIES...AND THE ECMWF MODEL HAS BEEN TRENDING TOWARD THIS
SOLUTION. GIVEN THE MODEL SPREAD AND THAT EACH SOLUTION IS
PLAUSIBLE...STILL A BIT CAUTIOUS ON HOW THIS WINTER STORM WILL
IMPACT THE FORECAST AREA SUNDAY NIGHT INTO TUESDAY.
CLOSE EXAMINATION OF QG FORCING SUGGEST THAT THE STRONGEST DYNAMICAL
LIFT MOVES AROUND OUR FORECAST AREA BUT NEVER DIRECTLY OVERHEAD.
SURFACE CYCLOGENESIS OCCURS OVER THE ERN COLORADO PLAINS AND NOT
SO MUCH ACROSS OUR AREA. NEVERTHELESS A FAIRLY STRONG COLD SWEEPS
NORTHWEST TO SOUTHEAST ACROSS THE FORECAST AREA MONDAY AFTERNOON
AND NIGHT THAT WILL LOWER SNOW LEVELS TO THE VALLEY FLOORS. HOW
MUCH SNOW REMAINS THE QUESTION FOR SUNDAY NIGHT AND MONDAY...BUT
APPEARS THAT THE SAN JUAN MOUNTAINS WILL BE THE PRIME BENEFICIARY
GIVEN MOIST SOUTHWEST FLOW AHEAD OF THE COLD TROUGH.
THE COLD TEMPERATURES RETURN ON TUESDAY WITH THE COLD TROUGH
DIRECTLY OVERHEAD. ALTHOUGH THE TROUGH AXIS MOVES DOWNSTREAM BY MIDWEEK...
STRONG NWLY GRADIENT FLOW PERSISTS THROUGH THE LONG TERM PERIOD.
EMBEDDED SHORT WAVES WILL BRING SNOW THAT FAVOR THE NORTHERN AND
CENTRAL PORTIONS OF THE FORECAST AREA. SURFACE INVERSIONS WILL
KEEP VALLEY TEMPS ON THE COLD SIDE...BUT NOT AS COLD AS IT WAS
EARLIER THIS MONTH.

SOME UNCERTAINTY REMAINS ABOUT THE TIMING OF THIS STORM...BUT IT APPEARS THE MAIN COLD FRONT AND BEST PRECIPITATION SHOULD MOVE THROUGH THE AREA LATE MONDAY AFTERNOON AND EVENING. THERE IS A CHANCE FOR SNOWFALL TO CONTINUE THROUGH TUESDAY AND WEDNESDAY.
