Hello to all…

..Moderate Snowstorm and/or Wintry Mix expected in interior Southern New England Tuesday Afternoon through Wednesday Morning. The evening commute will be significantly impacted by high snowfall rates before a changeover to a wintry mix inland and a wintry mix to rain in coastal areas..
..A Winter Storm Watch remains in effect from Tuesday Afternoon through Wednesday Morning for Franklin, Hampshire, Hampden, Worcester and Northern Middlesex Counties of Massachusetts for 4-7 inches of snow/sleet and one-tenth to two-tenths of an inch from a wintry mix of heavy snow, sleet and freezing rain..
..A Winter Storm Watch remains in effect from Tuesday Afternoon through late Tuesday Night for Essex, Central and Southeast Middlesex, Suffolk and Norfolk Counties of Massachusetts for 4-7 inches of snow/sleet and a light glaze of ice from a wintry mix of heavy snow, sleet and a brief period of freezing rain with wind gusts as high as 35 MPH..
..A Winter Weather Advisory is now in effect from 10 AM Tuesday Morning to 7 AM Wednesday Morning for Northern Connecticut for 2-4″ of snow and up to one-tenth of an inch of icing from a wintry mix of snow, sleet and freezing rain..
..A Winter Weather Advisory is now in effect from 10 AM to 10 PM Tuesday for Rhode Island and Southeast Massachusetts including Cape Cod for 1-4″ of snow and a light glaze of ice. Southeast coastal areas may see wind gusts around 40 MPH as the storm intensifies and tracks over the region..
..SKYWARN Self-Activation will monitor the winter storm Tuesday Afternoon into Wednesday Morning..

A moderate snowstorm and wintry mix is expected across Southern New England Tuesday Afternoon into Wednesday Morning with significant snowfall rates of 1-2″ per hour affecting the region during the late afternoon and evening commute that will bear close watching. The headlines depict the current thinking. Key factors for this storm system is when does the changeover from heavy snow to mixed precipitation occur across the region. Just 1-2 hours difference in the changeover in precipitation type could make the difference between higher snow accumulations versus more sleet and freezing rain. Given this difference, the Winter Storm Watch remains in effect for much of the interior until snow and ice totals are better known in those areas as higher resolution short-term model data comes in to determine more details.

SKYWARN Self-Activation will monitor the winter storm Tuesday Afternoon into Wednesday Morning.  Another update will be posted by 10 AM Tuesday Morning.
