As of 12Z this morning there was a low pressure center over northern Vermont with a really long cold front trailing southwest from it, draping across Pennsylvania and down into the south central states. The big picture looked like this:
Ahead of the front, a strong flow from the southwest gave me hefty tailwinds for the flight from KVKX back up to Connecticut. For most of the way I was seeing ground speeds on the Garmin 530W from 165 to 170 knots. The tailwind component was between 35 and 40 knots.
At one point N631S's ground speed reached 174 knots, or just over 200 statute mph. It's not often that you get that from a Cessna 182. Wheeee! Time en route from runway to runway was 1 hour 37 minutes - I believe that's a new record.
