It took awhile, but September has finally delivered a month with above average temperatures. The average temperature this month (considers highs and lows) is running 3.1° above normal. The last time we had an above average monthly temperature was February.

The month isn’t over yet, but the surplus of 3.1°, makes this month the warmest, when compared to average, since October of 2007.

So far in September we have seen 6 days in the 80s and 15 days in the 70s. However, it hasn’t just been warm here in Northeast Wisconsin. The entire state of Wisconsin and Minnesota has been running warmer than normal.

In Rhinelander, temperatures are nearly 5 degrees above normal, and in Duluth temperatures are 8 degrees above normal. Duluth is on its way to one of the warmest September’s on record. There will however, be a shot of cold air standing in its way.

A Canadian low pressure system will pull in the coolest air the Great Lakes region has seen in months for the start of the next work week. Temperatures will fall into the 50s in Duluth, which could be just enough to keep the city from achieving a new record.

Until Next Time,
