Colorado is getting hit by another wave of snow, this time with bitterly cold weather in store.

The snow began falling along the Front Range during the morning rush hour Monday, leading to accidents on roads already icy from last week's snow. A state trooper and Douglas County sheriff's deputy were taken to the hospital to be checked out after a crash on Interstate 25 near Castle Rock.

A winter weather advisory from the National Weather Service in Boulder says the heaviest amounts of snow are expected to fall in the late morning and afternoon. 

Between 5 and 9 inches is expected in the Denver area by Tuesday afternoon. Parts of the northern mountains are expected to get up to 16 inches of new snow.

Denver reached a high of 21 degrees just after midnight and the wind chill could reach negative 14 because of an arctic system that has pushed into the West.
