...WINTER STORM WARNING IN EFFECT FOR THE MOUNTAINS THROUGH MONDAY...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

SNOW...HEAVY AT TIMES...AND STRONG WINDS WILL CONTINUE OVER THE
MOUNTAINS THIS AFTERNOON. CONDITIONS WILL DETERIORATE RAPIDLY AS THE
SNOWFALL AND WINDS INCREASE. VISIBILITIES DOWN TO QUARTER MILE OR
LESS WITH OVER A FOOT OF NEW SNOWFALL AND WIND GUSTS IN THE 50 TO 75
MPH RANGE ARE POSSIBLE IN HIGHER AREAS OVERNIGHT. PEOPLE PLANNING
TRAVEL IN THE NORTH CENTRAL COLORADO MOUNTAINS SHOULD CONSIDER
CHANGING THEIR PLANS TO AVOID TRAVEL LATER TODAY OR TONIGHT AS THIS
STORM COULD HAVE SIGNIFICANT IMPACT ON TRAVEL.

IN AREAS EAST OF THE FRONT RANGE...STRONG WINDS WITH GUSTS OF 50 TO
60 MPH IN THE FOOTHILLS AND 30 TO 40 MPH ON THE PLAINS WILL CONTINUE
INTO THIS EVENING. THERE IS A SLIGHT CHANCE OF RAIN AND LIGHT SNOW
SHOWERS ON THE PLAINS OVERNIGHT. MOST AREAS WILL SEE LITTLE OR NO
ACCUMULATION...BUT THERE WILL BE SOME LOCALIZED HEAVIER SHOWERS THAT
COULD PRODUCE AN INCH OR TWO EARLY MONDAY MORNING.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

SNOWFALL WILL CONTINUE IN THE MOUNTAINS AND HIGH VALLEYS OF NORTH
CENTRAL COLORADO THROUGH TUESDAY MORNING. SNOWFALL MAY BE HEAVY
AT TIMES ON MONDAY ABOVE TIMBERLINE AND ON NORTHWEST FACING
MOUNTAIN SLOPES WHERE SEVERAL INCHES OF ADDITIONAL SNOW
ACCUMULATION IS POSSIBLE. NORTHWEST WINDS OF 35 TO 50 MPH WILL
ALSO CONTINUE TO PRODUCE BLOWING AND DRIFTING SNOW ON THE HIGH
MOUNTAIN PASSES AND AT BOTH PORTALS OF THE EISENHOWER TUNNEL
MAKING TRAVEL QUITE DIFFICULT IN THESE AREAS. MEANWHILE ON THE
PLAINS...THERE WILL BE A SLIGHT CHANCE OF SNOW ON MONDAY AND MONDAY
NIGHT WITH ONLY SPOTTY LIGHT ACCUMULATION POSSIBLE. STRONG
NORTHWESET WINDS ARE ALSO EXPECTED TO SPREAD OVER THE NORTHEAST
PLAINS MONDAY AND ESPECIALLY TUESDAY...WITH GUSTS BETWEEN 35 AND 55
MPH WHICH WILL CAUSE POOR VISIBILITIES IN BLOWING SNOW AND DRIFTING
SNOW. TRAVELERS SHOULD USE CAUTION BOTH DAYS AND BE PREPARED FOR
DIFFICULT DRIVING CONDITIONS...ESPECIALLY HIGH PROFILE VEHICLES
TRAVELLING ALONG I-76 OR I-70.

DRIER CONDITIONS SHOULD RETURN TO MOST AREAS BY LATE ON TUESDAY
WITH WARMER TEMPERATURES ON WEDNESDAY BENEATH A RIDGE OF HIGH
PRESSURE. LOOKING AHEAD TO CHRISTMAS DAY...A STORM SYSTEM SWINGING
OUT OF THE PACIFIC NORTHWEST MAY BRING ANOTHER ROUND OF SNOW AND
GUSTY WINDS TO THE HIGH COUNTRY. FOR AREAS EAST OF THE
MOUNTAINS...OTHER THAN A CHANCE OF RAIN AND SNOW THURSDAY NIGHT
WITH THE PASSAGE OF A COLD FRONT...DRY CONDITIONS AND NEAR
SEASONAL TEMPERATURES WILL PREVAIL THROUGH SATURDAY.

.SPOTTER INFORMATION STATEMENT...

REPORTS OF SNOWFALL OR HIGH WINDS WILL BE APPRECIATED.
