It's been a slow six weeks around here, with sparse delivery of State of the Atmospheres recently as the state has been rather predictable: clear, warm, and calm.

The start to September for the eastern two thirds of United States has been a hot one, and not surprisingly, Denver is currently running several degrees above normal for the month. Officially, the temperature is running 4.2° F above average through the first 13 days of the month.

Many of the analogs Brian Bledsoe discussed recently in his article on the CPC constructed analogs also featured very warm Septembers, especially for the eastern two thirds of the United States. Let's consider three of these analogs: 2002, 1997, and 1941 which combined produced a composite standardized temperature anomaly map which looks a lot like this month
