Here is today's forecast video. A rain producing system is heading toward the East Coast, though in parts of central and northern New England it will cause accumulating snow tonight. Once the storm leaves, somewhat milder air will spread into the Middle Atlantic states and hold until a cold front arrives this weekend. It appears that more unseasonably cold air will dominate the Great Lakes and Northeast next week.
Although most of the rain early this morning was associated with a low pressure area and a cold front heading east from the Midwest, spotty precipitation was breaking out all the way to the area between Virginia and Long Island. The precipitation in eastern North Carolina is left over from the storm that affected to East on Monday. This radar composite map is from 8:50 ET. On your mobile device, it is best to use a more localized radar picture so you can more easily see what is near your location.
In yesterday's report I made an analogy about predicting snow amounts using our 16 year old American Eskimo dog Sam as an example. I told Sam about it before taking this picture, but he just looked at me.
This map shows the pressure pattern around the big storm that some people in Boston and Providence are comparing with the Blizzard of '78.
In the worst-hit areas, plan for travel bans (for all non-emergency activities) because of impassable roads and extremely poor visibility. This map shows our projection for snow accumulations by early Wednesday. In many areas the heaviest snow should fall overnight and tomorrow morning.
In the worst-hit areas, plan for travel bans (for all non-emergency activities) because of impassable roads and extremely poor visibility. If you get stranded, rescue crews may not be able to reach you. Storms like this sometimes generate thunderstorms within the heaviest snow bands. The map shows predicted snow accumulations by early Wednesday.
It appears likely that many normal activities can go on through the day Monday, as long as the typical cautions for light to moderate snowfalls are observed. Tuesday will be an <strong>entirely different story</strong>. This map shows the GFS- predicted snowfall through 7 P.M. ET Monday:
The second storm we have been talking about will affect the Middle Atlantic region late Sunday and Sunday night. This GFS forecast map is for 7PM ET Sunday and shows precipitation amounts for the 6 hours up to that time.
