A frost can form at temperatures above freezing, while a freeze is simply at or below freezing temperatures. I think some sources use 36 F (2.2 C) as the criteria for a frost.
We're overdue for a cool winter, but part of me also feels like the recent warm bull**** is just our new climate regime.

I just don't see any reason why we'd have anything but a warmer than normal winter with La Niña and a strong SE ridge.

Hopefully I'm wrong.
The SE ridge seems to be somewhat squashed right now as there has been below normal temps a lot north of us in GA, SC, NC, TN, etc. Hopefully it doesn't become prominent in October/November. Also, La Nina doesn't necessarily automatically mean above normal here. 08-09 was La Nina and I remember that winter being cool down here. I believe 2010-2011 was La Nina as well.

08-09 was a great winter in the PNW. Not too often that both the NW and the SE have cool/cold winters.

I generally consider a freeze what the NOAA uses for a hard freeze, or temps below -2°C for 5+ hours
And I consider 0°C to -2°C a frost
