Ensembles suggest a shift in the overall atmospheric pattern late next week as mature low pressure system south of Alaska amplifies an elongated downstream ridge over the Plains, leading to the intrusion of unseasonably cold air into the Great Lakes region. This air mass may warrant frost or freeze headlines for part of the region next weekend.
