   expected too with the high astronomical tide.


   - Freezing rain mixed with sleet at times will be the main concern this
   morning through the afternoon northwest of the Boston to Providence
   corridor.


   - Growing concern for 0.25" to 0.50" of ice accretion across portions of

   interior northeast MA. Scattered power outages and downed trees a concern.


   - Flash Freeze occurs along and southeast of the Boston to Providence
   corridor between noon and 5 pm. Exact timing uncertain, but a rapid drop of
   temperatures into the 20s will occur resulting in hazardous travel.

   across much of interior southern New England. Precipitation ends between 4
   and 8 pm this evening.
