AFTERNOON THROUGH MONDAY...

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

.DAY ONE...TODAY AND TONIGHT

SNOW WILL CONTINUE OVER THE MOUNTAINS TURNING HEAVY WITH STRONG
WINDS DEVELOPING 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. CONDITIONS WILL APPROVE GRADUALLY THROUGH THE DAY
MONDAY. 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 ARE EXPECTED TO
DEVELOP WITH GUSTS OF 50 TO 60 MPH IN THE FOOTHILLS AND 30 TO 40
MPH ON THE PLAINS THIS AFTERNOON AND EVENING. THERE IS A SLIGHT CHANCE
OF RAIN AND LIGHT SNOW SHOWERS ON THE PLAINS OVERNIGHT. MOST

LOCALIZED HEAVIER SHOWERS THAT COULD PRODUCE AN INCH OR TWO EARLY
MONDAY MORNING.

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.

DRIER CONDITIONS SHOULD RETURN TO MOST AREAS BY LATE ON TUESDAY
WITH WARMER TEMPERATURES ON WEDNESDAY BENEATH A RIDGE OF HIGH

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
