...WINTER STORM WARNING FOR THE NORTHERN AND CENTRAL MOUNTAINS
LATE THIS AFTERNOON THROUGH MONDAY...

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

.DAY ONE...TODAY AND TONIGHT

SNOW AND BLOWING SNOW WILL DEVELOP IN THE COLORADO HIGH COUNTRY
LATE THIS AFTERNOON. THE SNOW WILL FIRST DEVELOP IN THE MOUNTAINS
AROUND THE RABBIT EARS PASS AREA BY MID TO LATE AFTERNOON...AND
THEN SPREAD TO THE FRONT RANGE MOUNTAINS AND SUMMIT COUNTY THROUGH
EARLY EVENING. THE HEAVIEST SNOWFALL WILL LIKELY REACH THE I-70
CORRIDOR FROM NEAR VAIL PASS THROUGH THE EISENHOWER TUNNEL AREA
DURING THE LATE EVENING AND OVERNIGHT HOURS. SNOW ACCUMULATIONS
BY LATE TONIGHT ARE EXPECTED TO RANGE BETWEEN 3 AND 8 INCHES
ACROSS MOST OF THE MOUNTAINS...WITH AROUND A FOOT IN THE RABBIT
EARS PASS AREA.

ON THE PLAINS...MILD TEMPERATURES TODAY WILL GIVE WAY TO A SLIGHT
CHANCE OF RAIN OR SNOW SHOWERS AND COLDER TEMPERATURES TONIGHT.
GUSTY WINDS TO BETWEEN 35 AND 55 MPH WILL OCCUR IN AND NEAR THE
MOUNTAINS AND FOOTHILLS.

A STRONG AND MOIST PACIFIC JET STREAM WILL BRING THE MOUNTAIN
SNOWFALL AND GUSTY WINDS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

SNOW...HEAVY AT TIMES ALONG WITH BLOWING SNOW WILL CONTINUE IN
THE MOUNTAINS SUNDAY THROUGH MONDAY. VERY POOR VISIBILITIES WILL
OCCUR OVER THE HIGHER MOUNTAIN PASSES WITH HAZARDOUS TRAVEL
CONDITIONS. ADDITIONAL ACCUMULATIONS THROUGH MONDAY AFTERNOON
WILL RANGE FROM 8 TO 14 INCHES WITH LOCALLY HIGHER AMOUNTS
POSSIBLE. AT LOWER ELEVATIONS IT WILL BE WINDY FROM THE FOOTHILLS
ACROSS THE PLAINS BOTH DAYS.

FOR TUESDAY AND WEDNESDAY THERE WILL BE A CHANCE OF LIGHT SNOW IN
THE MOUNTAINS. STRONG DOWNSLOPE WINDS WILL BE POSSIBLE IN AND NEAR
THE FRONT RANGE FOOTHILLS BOTH DAYS ESPECIALLY LATE AT NIGHT INTO
THE MORNING HOURS.

BY THANKSGIVING DAY THE FORECAST IS STILL UNCERTAIN AS TO WHETHER
A SHOT OF COLD AIR WILL AFFECT NORTHEAST COLORADO OR NOT. IF THE
COLD FRONT DOES MOVE INTO NORTHEAST COLORADO THEN THERE WOULD BE A
SLIGHT CHANCE OF SNOW. STRONG WINDS MAY OCCUR IN THE MOUNTAINS AND
FOOTHILLS ON THURSDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
HOWEVER...ANY REPORTS OF MOUNTAIN SNOWFALL OR GUSTY WINDS IN
EXCESS OF 50 MPH WOULD BE APPRECIATED.
