DENVER -- Highs will be between 55 and 60 degrees in Denver, Boulder and Fort Collins on Tuesday with partly to mostly cloudy skies. Enjoy it because the changes start on Wednesday.
Most of the precipitation starts as rain on Wednesday morning across the Front Range and gradually changes to snow.
Wind increases substantially with sustained wind by late morning of 30-65 mph.
On Tuesday morning, the National Weather Service issued a blizzard warning from 10 a.m. Wednesday to midnight Thursday for the Denver metro area, Aurora
A blizzard warning was issued Tuesday from 10 a.m. Wednesday to midnight Thursday for areas including Denver, Aurora, and the northern and southern metro areas.
A blizzard warning previously was issued for the eastern Plains for Wednesday and Thursday morning.
Snow continues across the Front Range through the evening rush hour Wednesday, then begins to taper off by midnight. Most the accumulation might occur as the sun sets. Temperatures will turn colder.
There is also a wind problem. As a result, there will be less snow accumulation west of Interstate 25 and much more east of I-25. So I-25 becomes a critical weather divider.
There will be 6-12 inches grand totals east of I-25 with 4-8 inches west of I-25.
The highest impact of wind and snow occurs over the eastern Plains. Plan on I-70 and I-76 potentially being closed.
The storm winds down quickly Thursday morning.
It will be a dry weekend with temperatures in the 30s and 40s.
