29F in CON in 1966.
With bare ground idk if we do it. We're getting to the point where we have to tack on a couple on the 18z 2m temps wit sun and bare ground. 4/9/97 at CON was 29F but that had -20C 850s getting near the Lakes Region. On the 6z euro it's a good 4C warmer.
I'll say no records, but cold enough to be annoying. Gotta watch for an early, cheap 5z high as well if the CAA doesn't come in fast enough.
