Transition to Autumn

September 20, 2012; 6:53 AM ET

Thursday 8:05 a.m.

In today's video, we look at the transition between warmth coming to the East Coast tomorrow into Saturday and a cool shot later in the weekend into early next week. By coincidence, the change almost matches the calendar change from summer to fall (at 10:49 a.m. EDT this Saturday). I say coincidence because there are many times when the calendar season changes and there is no immediate or noticeable change. In fact, there will be a warmup in the central and western Great Lakes on Monday, and the warming will spread on into the Northeast after that. So, the autumn chill is not taking over permanently.

There is a time-lapse movie at the end of the video. It was made last month on a day when thunderstorms were forming very close to my location. The sudden appearance of an outflow boundary may be noteworthy.
