...Life-Threatening Weather Conditions to Develop Tonight in Central Plains...

Blizzard Warnings are in effect for northeast Colorado, northwest Kansas and southwest Nebraska as a winter storm continues to strengthen. Snow will rapidly develop across the Plains later tonight and become widespread on Friday. This storm will be slow moving, so a prolonged period of moderate to heavy snow will persist into early Saturday morning. Snowfall rates of 1 to 2 inches per hour coupled with wind gusts up to 50 mph will create blizzard and life-threatening weather conditions across the region.
