Colder air headed to the Northern Plains

Refer to the Station Model Plot Tutorial to read the weather station observation plots. Temperatures in the 40s to lower 50s are being reported from a Canadian air mass entering the northern and central plains. The leading edge of the cold air extends across the Dakotas to Wyoming and western Montana. The weather is quiet ahead of this system with temperatures in the 60s and 70s. High pressure covers the eastern United States and much of the western United States. See the the Weather Briefing links on our home page for the latest discussions from the National Weather Service.
