...BLIZZARD WARNING FOR THE PLAINS OF NORTHEAST COLORADO LATE
TONIGHT THROUGH MIDDAY WEDNESDAY...
...WINTER STORM WARNING FOR THE NORTHERN AND CENTRAL MOUNTAINS...
NORTHERN FOOTHILLS AND NORTHERN PORTIONS OF THE FRONT RANGE URBAN
CORRIDOR TONIGHT THROUGH LATE WEDNESDAY MORNING...
...WINTER WEATHER ADVISORIES FOR THE HIGH VALLEYS...AND FRONT
RANGE URBAN CORRIDOR TONIGHT THROUGH LATE WEDNESDAY MORNING...

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

.DAY ONE...TODAY AND TONIGHT

MILD TEMPERATURES ARE EXPECTED AGAIN TODAY ACROSS THE
PLAINS. MOUNTAIN AREAS WILL ALSO BEGIN THE DAY UNDER MOSTLY CLEAR
SKIES. HOWEVER...CLOUDS WILL BE INCREASING OVER THE MOUNTAINS BY
THIS AFTERNOON WITH SNOW DEVELOPING BY EVENING. SNOWFALL OVER THE
MOUNTAINS MAY BECOME HEAVY AT TIMES TONIGHT AS A STRONG WINTER
STORM MOVES INTO THE STATE FROM THE WEST. SNOW ACCUMULATIONS IN
THE MOUNTAINS TONIGHT COULD BE UP TO A FOOT. WEATHER ON THE PLAINS
WILL ALSO UNDERGO A DRASTIC CHANGE TONIGHT AS A COLD FRONT MOVES
ACROSS NORTHEAST COLORADO WITH GUSTY NORTH WINDS BEHIND IT.
TEMPERATURES WILL TURN MUCH COLDER TONIGHT WITH SNOW DEVELOPING.

OVERNIGHT...DANGEROUS WINTER WEATHER CONDITIONS ARE EXPECTED TO
SPREAD ACROSS NORTH CENTRAL AND NORTHEAST COLORADO. SNOWFALL
ACCUMULATIONS IN THE MOUNTAINS WILL MAKE TRAVEL DIFFICULT. ON THE
PLAINS...WIDESPREAD SNOW WILL COMBINE WITH INCREASING NORTH WINDS
OF 30 TO 40 MPH TO PRODUCE POOR VISIBILITIES IN BLOWING SNOW.
WINTER STORM WARNINGS WILL BE IN EFFECT FOR THE MOUNTAINS AND FOR
THE NORTHERN I-25 CORRIDOR WHILE A BLIZZARD WARNING WILL GO INTO
EFFECT FOR MUCH OF NORTHEAST COLORADO LATER TONIGHT. RESIDENTS
IN THE MOUNTAINS AND ACROSS THE NORTHEAST PLAINS SHOULD PLAN ON
COMPLETING ANY TRAVEL PLANS BY EARLY EVENING SINCE DANGEROUS
DRIVING CONDITIONS ARE EXPECTED OVERNIGHT.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

BLIZZARD CONDITIONS WILL CONTINUE OVER THE PLAINS THROUGH MIDDAY
AS NORTHWEST WINDS OF 25 TO 40 MPH WITH GUSTS TO 55 MPH CREATE
VERY HAZARD TRAVEL CONDITIONS DUE TO ZERO VISIBILITIES AT TIMES.
ELSEWHERE SNOW WILL CONTINUE OVER THE AREA IN THE MORNING BUT
SHOULD BEGIN TO END FROM WEST TO EAST BY LATE MORNING AS A STORM
SYSTEM MOVES RAPIDLY INTO THE CENTRAL PLAINS BY AFTERNOON.
TOTAL SNOWFALL ACCUMULATIONS WILL RANGE FROM 10 TO 18 INCHES IN
THE MOUNTAINS WITH 4 TO 10 INCHES IN THE FOOTHILLS. ACROSS
NORTHEAST COLORADO AMOUNTS WILL BE IN THE 2 TO 6 INCH RANGE.

FOR THURSDAY THROUGH THE WEEKEND IT WILL BE DRY WITH TEMPERATURES
RISING BACK TO SEASONAL LEVELS FOR SATURDAY AND SUNDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
HOWEVER...REPORTS OF HEAVY SNOWFALL AND HIGH WINDS WILL BE
APPRECIATED TONIGHT.

Only three inches in Fairplay? Mild disappointment.

Per CDOT: Winter weather expected starting at midnight; 4"-8" in the NE, 2"-6" front range, and 10"-18" in the mountains. Wind speeds up to 50 mph, particularly east of I-25. Chain laws likely in the mountains, traction laws requiring adequate snow tires, chains, or 4WD for all vehicles possible anywhere in the state.

From Meteorologist Steve Hamilton: Here's the latest watch/warning map from NWS. I'm forecasting snow to begin by mid-evening, lasting into mid-day tomorrow. This storm is a fast-mover, so snow totals will be less than 8" for most of the foothill locations. Expect winter driving conditions. Up to 16" for the higher mountain passes, and blizzard conditions for the eastern plains.


Here is the latest expected snow-total map from NWS. Winter Weather Advisory goes into effect at 10 p.m. for our Mountain Town locations (except Fairplay which will escape with under 3 inches of snow). Bailey will also escape with a lighter amount of snow. I'm going to play it safe and call for 2 - 4 inches. Probably no more than 3", but just to be on the side of caution. The highest accumulations will occur in the Morrison, Conifer and Evergreen areas, with up to 7" possible by midday Wednesday. This storm is a fast-mover, and will be out of our area by Wednesday afternoon. You might need the snow blower for this one, unless you enjoy shoveling. Note: The higher mountains are under a Winter Storm Warning: More snow and wind expected there. -Meteorologist Steve Hamilton.
