A similar pattern is expected to take shape late this week, through the upcoming weekend, into the first half of next week. A storm system will dislodge polar air into eastern parts of the lower-48. This means temperatures will drop like a rock and be well below average. Some areas will experience temperatures 10-25 degrees below average by this weekend into early next week.

The storm system paired with such a cold air mass will deliver the first snow of the season to many across the Northern Plains, Great Lakes, Ohio Valley, and Northeast late this week and into the weekend. The heaviest snow will fall across the eastern Dakotas and northern and central Minnesota. This is where over 1 foot of snow will fall. Secondary areas of heavier snow will set up on the eastern shores of the Great Lakes and along the higher peaks of the Appalachians. Join the Firsthand Weather Supporter Group today!
