Great Box disco 605am:

 

*** very heavy snow with 1 to 3 inch per hour rates will make for a
very difficult and dangerous morning commute ***

 

605 am update...

A classic front end thump of very heavy snow is underway early this
morning across southern New England. Strong warm advection was
resulting in tremendous Omega in the snowgrowth region...with 1 to 3
inch per hour snowfall rates. Roadways are rapidly deteriorating
and visibilities down to one quarter of a mile will make for a very
messy and dangerous morning rush hour. Have even heard of some isolated
reports of thunder.

The main concern continues to be how fast the warm air aloft will
change places over to sleet and freezing rain. Dual pol radar
indicating that transition to sleet/freezing rain was moving rapidly
north across Rhode Island and will be approaching the South Coast
through 7 am. This will then overspread northern CT/Rhode Island
and southeast Massachusetts between 8 and 11 am. Given that its snowing so
hard...a small timing error in thermal profiles will make for a
significant difference in accumulations. We still like our current
snowfall forecast with a general 5 to 9 inches south of the
Pike...except less on cape/islands. Expecting 8 to 12 inches with
perhaps a few higher amounts not out of the question to the north
of the Massachusetts Turnpike. The precipitation should also remain in the
form of snow north of the Pike. To the south of the
Pike...transition to sleet and then freezing rain. A tenth to up to
a quarter inch of ice accretion is possible across northern
CT/western Rhode Island later this morning/afternoon. Boundary layer warms
enough to change far southeast Massachusetts/southern Rhode Island to all rain this
afternoon.

Sleet can be like 2 to 1 or 4 to 1 depending on the exact compositiong and how much pixie dust is mixed in with the sleet. Sometimes you get horribly formed flakes mixed in that look almost like dandruff...esp when the BL is really cold. If the sleet is more "wet" and almost dead straight with no dust mixed in, then its usually closer to 2 to 1.

Jet blue too. People here pacing. Just board the damn plane and let's get out of here. I heard at dunkin donuts only one southwest flight getting out. We're from New England we know how to fly in the snow.
