NE Washington state. This is not unheard of to have a freeze this early for us.

Wow, we are way up in Maine and still have 3-4 weeks before I'm expecting a hard freeze. Perhaps some light frost between now and then, but tomatoes and peppers under cover we typically pull 2nd week of Oct and still harvest cold-tolerant produce out of the field until end of Nov.
My greenhouse is still doing fine and normally we get until early October but this year we got a surprise.
