MONDAY AND MONDAY NIGHT AS A POTENT PACIFIC STORM SYSTEM PASSES OVER
COLORADO. HEAVIEST SNOWFALL WILL LIKELY OCCUR OVER AND ALONG THE
EAST FACE OF THE FRONT RANGE MOUNTAINS MONDAY AFTERNOON AND
EVENING BECAUSE OF A DEEP AND MOIST UPSLOPE FLOW. SOME AREAS OF
THE FRONT RANGE COULD SEE 1 TO 2 INCH PER HOUR SNOWFALL RATES
DURING THIS TIME PERIOD. SNOWFALL RATES ARE NOT EXPECTED TO BE AS
GREAT AT LOWER ELEVATIONS. HOWEVER BECAUSE OF THE LONG DURATION

ON THE PLAINS WITH HIGHER AMOUNTS POSSIBLE ON THE PALMER
DIVIDE...4 TO 9 INCHES IN THE HIGH MOUNTAIN VALLEYS...AND ANYWHERE

IN ADDITION...STRONG AND GUSTY NORTHEAST WINDS MONDAY NIGHT AND
TUESDAY COULD PRODUCE CONSIDERABLE BLOWING AND DRIFTING SNOW ON

THIS STORM SYSTEM HAS THE POTENTIAL TO SEVERELY DISRUPT AIR AND
GROUND TRAVEL ACROSS COLORADO AND SURROUNDING STATES MONDAY AND
TUESDAY. TRAVELERS SHOULD PREPARE TO MAKE ALTERNATE ARRANGEMENTS
SHOULD ROADS BE CLOSED AND FLIGHTS BE CANCELLED DUE TO INCLEMENT
WINTER WEATHER.

BEGINNING WEDNESDAY...CONDITIONS WILL GRADUALLY WARM AND DRY ON
THE PLAINS. FOR THE HIGH COUNTRY...A MOIST NORTHWEST FLOW AND THE
OCCASIONAL WEATHER DISTURBANCE WILL CONTINUE TO PRODUCE PERIODS
OF LIGHT SNOWFALL THROUGH SATURDAY.

STAY TUNED FOR THE LATEST UPDATES ON WHAT WILL LIKELY BE A MAJOR
SNOW STORM FOR MOST OF COLORADO.
