Right now it's 2F, but it went down to -4F overnight. One day last week our high was -8F, before the wind chill. I can't put a date to it but I know one winter the temp was down to -15F, before the wind chill.
Highest temp I think I've experienced was around 102F one August on a Disney World Trip- but it sure felt hotter due to the heat index. Fortunately this was the longest trip we've ever taken so we didn't feel bad if we only spent a few hours each day in the parks. I felt bad for those on the "once in a lifetime" trip going from rope drop til park closing!
ETA- I posted the above a couple of days ago. Right now, it's -12 out, and with the wind chill it's -21F. I'm awake right now because I got cold; it's 55F in my old house, even with the thermostat set to 60. I'm not going outside to see what it feels like.
