Surprise

The weatherman said 1-3 inches of snow overnight Sunday into Monday morning. Additional accumulation Monday of an inch or maybe a smidge more. Tapering off during the mid-afternoon on Monday. Less than 10% chance of snow Monday night/Tuesday morning.
By 4 pm Monday afternoon, we had a total accumulation of nada, ditto zilcho, cookie, zfft. Nothing. We did have periods of sunshine Monday morning.

The map above shows a classic nor'easter (ok, it's a very tiny one, but still...)--meaning the system is rotating counter-clockwise off the ocean. It started snowing up to Portland mid-afternoon. It started here at about 7pm and has been snowing off and on since. We've got the two inches they predicted, just a bit later than they thought
