Looking ahead to next week, there could be a potentially large trough or a slow-moving upper-level system developing somewhere from the upper Midwest and Great Lakes region, extending southward to the Ohio Valley.
Computer models continue to analyze the potential setup of this trough, indicating that changes to the forecast may occur in the coming days.
If this trough develops, we might experience several days of relatively cool temperatures in the Northland area late next week or next weekend. Meanwhile, much of the western US is anticipated to have very warm, if not hot, temperatures next week.
