CFS/7 Day Temperature Departure
September 27, 2021
Warm, summer-like temperatures will continue to dominate the northern half of the United States as we head into October....
A rather benign upper level wave pattern has resulted in a large area of above normal temperatures across a large part of the United States, and will continue as such over the next 7 to 10 days. Tropical weather activity will become influential in bringing a pattern change by the middle of October. Stay tuned as we track these changes over the next 2 weeks.
