Colorado is set to experience a dramatic shift in weather conditions as an Arctic blast is expected to sweep through the state following a period of mild temperatures. Residents have been enjoying relatively warm and easygoing weather through the middle of the week, but forecasters are warning of a significant change as a cold front approaches. By Friday, temperatures are predicted to plummet as an Arctic air mass settles over the region, bringing with it much colder conditions. This abrupt transition will mark a stark contrast to the recent mild weather, with temperatures expected to drop substantially below average for this time of year.
