...WINTER-LIKE STORM SYSTEM TAKING AIM ON NORTHEAST AND NORTH
CENTRAL COLORADO...

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

.DAY ONE...THIS AFTERNOON AND TONIGHT

SNOW SHOWERS WILL STEADILY INCREASE IN COVERAGE...ESPECIALLY IN THE
HIGH COUNTRY THIS AFTERNOON AND THEN OVERNIGHT OVER THE ENTIRE
OUTLOOK AREA IN ADVANCE OF A MOISTURE LADEN STORM SYSTEM MOVING
OVER THE FOUR CORNERS REGION. SNOWFALL ON THE PLAINS MAY BE MIXED
WITH RAIN OR DRIZZLE THROUGH MID-EVENING BEFORE CHANGING OVER TO
ALL SNOW BY MIDNIGHT. THE FRONT RANGE MOUNTAINS AND FOOTHILLS AS
WELL AS THE SOUTH PARK AREA WILL SEE MODERATE TO HEAVY SNOWFALL
DEVELOP THIS EVENING WITH MOIST UPSLOPE FLOW INCREASING AHEAD OF
THIS STORM. THESE AREAS COULD SEE SNOWFALL RATES IN AN EXCESS OF
AN INCH PER HOUR OVERNIGHT. THE PALMER DIVIDE MAY ALSO SEE
PERIODS OF MODERATE SNOWFALL OVERNIGHT GENERALLY FROM MID-EVENING
ONWARD WITH LIGHTER SNOWFALL FROM DENVER NORTHWARD AND A RAIN-
SNOW MIX FARTHER OUT ON THE PLAINS.

SNOW ACCUMULATIONS BY MORNING ARE EXPECTED TO RANGE FROM 1 TO 4
INCHES WITHIN THE I-25 URBAN CORRIDOR FROM DENVER NORTHWARD...AN
INCH OR TWO FARTHER EAST...AND ANYWHERE FROM 3 TO 7 INCHES IN THE
FRONT RANGE MOUNTAINS AND FOOTHILLS...SOUTH PARK AND PALMER
DIVIDE. MUCH OF THE SNOWFALL ON THE PLAINS WILL PROBABLY MELT ON
THE RELATIVELY WARM ROAD SURFACES. THE HEAVIER SNOWFALL IN THE
HIGH COUNTRY COULD REDUCE VISIBILITIES TO LESS THAN A QUARTER
MILE AT TIMES AND CAUSE ROADS TO BECOME SLUSHY AND POSSIBLY SNOW
COVERED.


.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

A PACIFIC STORM SYSTEM OVER THE FOUR CORNERS REGION FRIDAY MORNING
WILL MAKE ITS WAY ACROSS COLORADO THROUGH FRIDAY NIGHT. PRECIPITATION
WILL CONTINUE THROUGH AT LEAST FRIDAY EVENING...WITH SIGNIFICANT

5 INCHES THROUGH FRIDAY NIGHT...WITH ACCUMULATIONS OF 1 TO 3
INCHES ACROSS THE NORTHEAST PLAINS WHERE LIGHT SNOW OR A MIX OF
RAIN AND SNOW EXPECTED.

THE STORM SHOULD EXIT THE STATE SATURDAY...LOWERING THE CHANCES OF
PRECIPITATION AT THAT TIME BUT ANOTHER STORM MAY DEVELOP AND BRING
ANOTHER ROUND OF RAIN AND SNOW TO THE AREA SATURDAY NIGHT AND INTO
EARLY NEXT WEEK. TEMPERATURES WILL BE WELL BELOW NORMAL THROUGHOUT
THE PERIOD.

.SPOTTER INFORMATION STATEMENT...
