More than a dozen Colorado school districts are altering their schedules on Monday as winter weather impacts the state.

Some eastern Colorado school districts will be closed on Monday while others have late starts.

Bennett School Dist. 29-J, Byers School Dist. 32-J, Kiowa C-2, Lewis-Palmer District 38, and Strasburg School District 31-J are among the districts closed on Monday.

The Air Force Academy, Fort Carson, Akron School District R-1, and Gilpin County School District RE-1 have delayed starts on Monday.

Rain began falling Sunday evening in much of the Denver area before changing to snow around sunset. The snow was heavy at times Sunday night and early Monday morning.

The snow and blizzard conditions caused many flights to be delayed or canceled at Denver International Airport on Sunday and Monday.

The snow is forecast to end Monday morning as the storm moves out of the state, but cold and windy conditions will remain. It will also be chilly, with highs stuck in the upper 30s — about 20 degrees below average — in Denver on Monday.
