As of 6 am, we've had maybe three to four inches of snow, and it's still
coming down, though lightly.

Out on the Bay, today:
NW winds 25 kt with gusts up to 35 kt. Waves 3 to 4 ft. Morning snow. Vsby
1 nm or less...increasing to 1 to 3 nm this afternoon.

At the moment, our forecast states:

Snow this morning...then a chance of snow this afternoon. New snow
accumulation of 1 to 3 inches. Total accumulation 5 to 10 inches...less
along the Chesapeake Bay. Breezy with highs in the mid 30s. Northwest
winds 15 to 25 mph. Gusts up to 40 mph this morning.


I just looked outside. Maybe 3 inches and it's not snowing at all at the
moment. Weather Channel says to expect 15+ inches in this area, but it's
hard to believe that's going to happen.

I noticed on the official NOAH storm forecast that they say "localized
areas may receive more snow due to snowfall enhancement due to thunder".
What does thunder have to do with snowfall amounts? Interesting thing to
research.

I was wrong. It's snowing hard. It is very fine and wind blown, but it's
coming down pretty good.

First, don't be blaming this snowfall on me. ;-) Secondly, thunder
doesn't increase the amount of snow, but is a symptom of "convection
snow." Normal snow clouds are relatively low, but when you have a very
unstable airmass, convection will build clouds to a much higher level,
much like a summer thunderstorm. The added height means added snowfall.
Sometimes reaching several inches per hour. As is a thunderstorm, the
effect is usually local.

The above explanation is well short on the actual science, but is all I
remember after asking a local amateur meteorologist, "What the f... is
convection snow?"
