Here's what I expect in terms of snowfall, mostly on grassy surfaces, by 2 AM Wednesday. See map below. Take the higher number of my snowfall "range," if you live on a hill or on a higher elevation.
Wet snow showers, 80% chance, trace to as much as 2" on hilltops in the Valley, turning colder, lows in mid to upper 20s.
Normal low for this time of year: 32°
Grab the sunglasses. Sunshiny, bright & chilly, highs in the mid 40s.
Normal high for this time of year: 51°
Mostly clear, lows in the upper-20s.
Mostly sunny, high in the lower 50s.
So weather does not surprise you
