The change in our weather from August to September has been abrupt.

6 of the first 9 days this month have had temperatures only in the 60s.

So far, the monthly average is 2 degrees below normal in Portland; closer to 3 degrees below normal in Augusta, Bangor and Caribou.

The jet stream has been near or over us, putting northern New England in a cooler northwest flow for most of the time this month.

Looking way ahead though, there are signs the jet stream may relax a bit, sending the above-average temperatures our way.

There's actually plenty of heat out there. Most of the country is baking, with high temperatures today in the 90s as far north as Ohio. 

The Nashville area could approach 100 degrees!

We'll get a piece of this heat tomorrow (Wednesday). 80s are likely, especially in southern Maine, with high humidity

But the cooler air returns Thursday through the weekend.

Odds seem good the middle or end of next week will be warm. Granted, our average high temperatures are on the decline -- by next week they'll be closer to 70 degrees.

Some of the early computer model guidance suggests we could be way warmer than that at some point between next Tuesday and next Friday, so don't put away the summer clothes just yet.
