Downtown Denver

A blizzard warning is in effect for the entire Denver metro area until 6 a.m. 
Friday morning. That blizzard warning covers the entire eastern half of 
Colorado into Friday.

Light snow began our Thursday but it grew heavy by 9 a.m. across the Front 
Range. By 11:30 a.m. there was officially 11 inches of snow in Boulder.

Most schools across the region that aren't on spring break closed for the day.
 Colleges including the University of Denver, University of Northern Colorado,
 Colorado State University and Regis who were in session called off classes
for  the day.
As far as major road closures:

-- Emergency crews shut down the Boulder Turnpike (Highway 36) before noon.

-- Colorado Department of Transportation crews were blasting for avalanches on
 Vail Pass, leading to an hour-long morning closure.

-- Interstate 70 was closed in several different spots for short bursts 
Thursday. At 12:30 p.m. the westbound lanes were closed at Federal due to a 
multi car pileup at Sheridan.

-- Interstate 25 was shut down from Wellington to the Wyoming border at 10:23 
a.m. due to a crash involving many vehicles. (More)

Two surges of moisture will keep it snowing all day as upslope kicks in for
the  Front Range.

Expect about a foot for Denver all the way up toward Fort Collins.
