Good morning everyone

The overall forecast remains on track, but we wanted to just give a brief update based on some of the latest data we are currently reviewing.  The first image we are attaching indicates a snowfall forecast from one of our more reliable computer models.  While it is not meant to  be taken verbatim our thinking is that it has the correct idea. A swath of 3 to 6 inches of snow appears reasonable within 20 miles north or south of the MA turnpike, including the Berkshires as well as the greater Worcester and Boston metro areas.  Areas near the NH border and particularly from near Hartford, CT to the south coast of RI may end up more in the 1 to 4 inch range.  

In addition, we also have attached a loop indicating the approximate arrival and ending times of the snow.  The general theme is that the steady light snow will arrive in most locations between 4 and 8 pm this evening.  While snowfall rates should be light during this time, some roads may become coated with snow for the evening commute with the highest risk in western MA.  The heaviest snow still looks to occur from 10 pm to 4 am, but snowfall rates will generally remain under 1 inch per hour.  The snow wraps up in most areas in time for the Thursday morning rush hour, except along the eastern MA coast where it may linger a few hours longer.  Nonetheless, untreated roads will be snow covered and slippery for the Thursday morning commute. 

We will have a full briefing package out later this afternoon.  Just wanted to share our latest thinking along with a few images.

Thank You
