I always get chills watching the snow balls flying.I'm a weenie for cold so I think my fave may be the Ten playoff game. That was old school, ice bowl worthy cold.
Quite possible...it's tough to measure out there with wind too. There was only a couple handful of reports in the PNS and the final obs were up to 24hrs apart.
There are a few here in parking lots shaded on the north side that never fully melted from October. I still have 1" OTG from the series of January crap that has slowly been melting/sublimating away.
