Ended up with 1.33" rain for the 2-day 10/16 - 10/17 event and only made it up to 58 yesterday after a low of 41. This morning I bottomed out at 37 with a dp of 36, so the potential was there for frost, although I mainly saw condensation and not actual frost crystals (ground may still be too warm for it). Currently 42 and partly cloudy with dp 41, which means still some low-lying condensation around.
