Today was my first frost, and where a pea leaf was holding a little water, it froze solid. Local weather stations report things like 28 - 30 F. Except for one night a week or two ago (35), my lows have all been in the 40s.
That agrees with tables I've found for "average first 28 F freeze", but it's 6 days AFTER the 90% date for first 32 F frost.
