URGENT - WINTER WEATHER MESSAGE
National Weather Service Denver CO
257 AM MST Mon Dec 12 2022

...POTENT WINTER STORM HEADED FOR THE REGION...

.A strong winter storm system will track toward southeast Colorado 
tonight, and then lift northeast into Nebraska by Tuesday. This 
track means that significant winter travel impacts can be expected 
especially over portions of the northeast plains of Colorado into 
the Nebraska Panhandle and parts of eastern Wyoming. Blizzard 
conditions will likely develop over northeastern Colorado as the 
storm intensifies late tonight and Tuesday morning. Strong winds are 
expected to gust to 50-60 mph, creating blizzard conditions.  There 
is still some uncertainty about snow amounts, but the heaviest snow 
should be on the plains east of Greeley and Denver, focusing toward 
the Akron, Sterling, and possibly Fort Morgan areas.

People planning travel north or east of Denver Tuesday, or those 
with outdoor livestock interests should prepare for likely blizzard 
conditions on Tuesday and continued cold and windy weather behind 
the storm Wednesday and Thursday.
