Winter Storm Warning
URGENT - WINTER WEATHER MESSAGE
National Weather Service Denver CO
140 PM MST Sun Nov 24 2019
...HEAVY SNOW LIKELY MONDAY NIGHT INTO TUESDAY...
.A winter storm will strengthen as it moves over the mountains and across northeastern Colorado and neighboring states Monday night into Tuesday. A large area of heavy snow is likely from the northern Colorado and southern Wyoming mountains eastward into western Nebraska and northwest Kansas. The heaviest snow will begin in the mountains Monday afternoon and spread southeast to the Denver-Fort Collins area during the evening, and across the rest of northeast Colorado by about midnight. The snow will end from west to east during the day Tuesday. The heaviest snow is likely to occur late Monday into the early morning hours Tuesday.
This storm will likely cause significant travel difficulties due to the amount of snowfall. A widespread area with a foot of snow from about Interstate 70 northward is possible. Conditions will deteriorate Monday evening and will be worse on Tuesday morning just after the heaviest snowfall occurs. While blizzard conditions are not expected, north winds at 15 to 30 mph will produce some blowing and drifting snow on the plains during the day Tuesday, which may hamper plowing of roads. Conditions will improve Tuesday afternoon as the snow moves eastward and winds decrease.
People planning travel in northeastern Colorado Monday night or Tuesday should monitor future forecasts and begin to consider alternatives. There is a chance that travel could become nearly impossible across the I-25 urban corridor and across much of the northeast plains including the I-76 corridor by Tuesday morning, so residents should be prepared for that possibility. Closed or impassible roads due to heavy snow are possible in the warned area.
