Snow in May is rare, not to mention downright cruel. Getting snow to accumulate in May is almost unheard of. Well, guess what, there's a chance we see both late tonight and tomorrow morning.
A mini Nor'easter will travel up the East Coast and plague us for a couple of days. Rain will overspread the area tonight.
Aside from the mountains, it will be mild enough for rain at the start. Overnight, however, the rain will become steadier and more intense. A combination of evaporational cooling and cold air drawn down from aloft in heavier bursts will allow for cold rain to mix or even flip for a time to wet snow, especially over the hilltops tomorrow morning. It's even possible for flakes to mix in down to the coast.
During the day, even though we won't see sun, UV rays will warm us a few degrees, eliminating snow from the equation except for the highest elevations. But it will remain wet, cold and raw all day long.
The mountains will pick up a few inches of heavy snow. While unlikely, it's possible that thin, slushy coatings show up on the grass, decks or cartops elsewhere. If we do happen to get any snow accumulation, it will be the latest ever recorded.
