Snow will develop north of Denver and in the northern mountains in the early morning hours, then along Interstate 70 around rush hour, and further south during the morning. 

During most of this event, there will be rain or snow that melts for elevations below 5000 feet. Below 7000 feet, snow is generally expected to melt on the roads. Temperatures at lower elevations will be a little above freezing during the day Tuesday, then in the upper 20s to around 30 Tuesday night.  This may lead to minor snow accumulations on grassy areas on the plains Tuesday night.

In the mountains and higher foothills, there will still be substantial melting during the day Tuesday, but it will be cold Tuesday night so there is a better chance of some slush, snow, or ice on the roads.  The main threat is during periods of heavy snow on the east side of the Front Range Tuesday evening.

Snow will end north of Denver Wednesday morning, and midday/early afternoon in areas along and south of I-70.

While most of the snow is expected to melt on the roads, there may be problems from accumulations on tree branches leading to falling limbs and power outages if the snow accumulations are on the higher end of our expected ranges.

Expected snow totals (on grassy areas):

Front Range mountains and foothills: 8-18", with higher amounts in backcountry areas

Douglas County/Monument Hill and Park County: 6-12"

Front Range cities from Denver to Fort Collins and I-70 east to Limon: 3-7"

Northeast plains: 1-4"
