Just to add to this, the most dramatic one I remember was late February 2015. We warmed up into the mid or maybe even upper 50s that day with sunshine (needless to say, there was plenty of cliff jumping as we blew through our forecasted high that day), and then by mid-evening it was pouring snow with temperatures in the low 30s (it might've briefly started as rain, but I don't recall). That was a wet snow and the warmer soil temps as a result of the plentiful sunshine and warm temperatures that day definitely made sticking to the road, etc. a bit harder, but it came down with such fury that we ended up with 6.5" by the wee hours of the morning. I don't recall the setup for that one really well, but it was a beautiful snow.51 here, which is right about where we were forecasted for our high. We've had plenty of good storms where we were this warm or warmer the day before, but not cooling off tonight is the bigger concern.
I also remember as a kid it being in the 70s / 80s one day in late March, and the next morning we had a dusting of wet snow. It wasn't much, though.
