Good afternoon,

Please find attached a one page briefing and supporting graphics regarding
dangerously cold wind chill temperatures expected Friday night into
Saturday and potentially impactful snow on Sunday/Monday. Additionally find
some key points below.

*Dangerous Cold Friday night into Saturday*

   - High confidence that an intrusion of arctic air will result in wind
   chill temperatures between -10 and -20 degrees Fahrenheit Friday night into
   Saturday.

*Increasing potential for moderate impacts from accumulating snow
Sunday-Monday*

   - High confidence that portions of southern New England will experience
   at least moderate impacts from accumulating snow during the Sunday-Monday
   time frame.
   - Confidence in specific snowfall amounts is low at this time.


We will provide an updated briefing no later than 10AM Thursday.

Have a great afternoon,

Meteorologists Rob Megnia, Kevin Cadima, and Candice Hrencecin
