Tuesday Winter Weather Event

A small to moderate snow event will impact New England tomorrow.  The snow begins after the AM commute but will impact the PM drive.  The National Weather Service has issued Winter Weather Advisories for much of the region

NWS Boston Watches/Warnings

Here is my forecast

Here are the temperatures as of 7 PM

Temperatures tonight will drop near 0.  The storm approaches SW CT by 9 AM.  Will  take some time for the air to saturate due low temps/dew points.  Temperatures tomorrow west of 495 and North of the the Prov-Boston line should stay in the low 20's.  SE MA will warm up to near freezing while the Cape will go above freezing and change to rain.

This is not a major event by any means.  The trouble lies in the timing.  During these systems strong bands of snow can develop that drop 1-3 inches an hour.  That is difficult to drive in when caught on the highway.  It may only last a few minutes or it could sit an dump.  Therefore plan on a long commute tomorrow evening.  I'll update in the AM.
