Blizzard Warning!

A Blizzard Warning has been issued for the MA coastline, including Boston. This warning was issued because the strongest winds will be along the coast, creating blizzard conditions. Snow will begin after midnight, and blinding snow will continue thru the morning. Stay off the roads unless you have to go out. Also, I will watch the mix line closely, because it could come close to the city for a brief time- which may cut down amounts slightly.  However, at this time I am still predicting all snow, and a lot of it. I think the mix will be confined to the south shore and Cape.  

Alerts: 

A Blizzard Warning is in effect for the coast of MA, including the city of Boston. The warning expires at 8 PM Wednesday. 

A Winter Storm Warning is in effect elsewhere. 

A High Wind Warning is in effect for Nantucket. Gusts may approach Hurricane Force!

    Nolan, I'm confused. The media refers to this storm as a nor'easter. But I saw storm radar maps on weather.com last night showing a gigantic storm coming in from the west (Michigan, Ohio, Pennsylvania), and now it's showing the storm moving down from Maine. It's not what I think of when I hear the term nor'easter.

    Hey Chris, this was a nor'easter because the storm from the west combined with storm off the east coast and intensified as it passed over the Cape and Islands. Winds were from the NE during the height of the storm, which is why it is called a nor'easter. Now, the storm is in the Gulf of ME and bands are looping all the way around the storm and into Boston.
