A powerful low pressure system is forecast to track across northeastern Colorado into central Nebraska through Wednesday, bringing strong winds and heavy snow to many areas.
Snow amounts could change depending on the exact track of this low pressure system. Travel will be difficult beginning Monday night and especially Tuesday into Tuesday night due to strong winds, heavy snow and low visibility.
