ROANOKE, Va. – This time last year, we were breaking record high temperatures. Temperatures were in the 90s, and we were still lounging by the pool. Fast forward to 2020, and autumn is actually behaving like autumn.

A front moved through Friday morning. Behind that, it will be about 10° cooler than Thursday afternoon. Highs for many will only reach into the 60s, thanks to a cool breeze out of the northwest.

A clear sky at night and a calming wind will allow the limited warmth to escape, leading to a colder night ahead.

The clear sky will also give us a clear view of the full Harvest Moon with Mars cozying up right next to it in the eastern sky.

If this kind of weather isn’t your cup of tea, you’re in luck. The jet stream begins to lift back to the north next week. By Wednesday, high temperatures will likely be around 75-80°.
