Another weekend is approaching and it appears another snowstorm may be in the works for part of weather-weary New England with a close call for part of the mid-Atlantic.
On Tuesday, AccuWeather.com informed its followers that a developing weather pattern over the United States could lead to big East Coast snow events during the next week or more. See the Omega Block story for more information.
A significant storm will impact New England Saturday into Sunday. The question is how will marginal temperatures affect the extent and duration of rain and snow.
If the storm develops to its full potential, portions of central New England could be on the receiving end of a foot or more of wet snow with strong wind and colder air being drawn into the storm.
If the storm ends up being on the weak end of the spectrum, more rain would be involved with much lower snowfall totals.
There is also the possibility that the storm may develop fast enough to throw significant rain, snow or both over portions of the mid-Atlantic.
The overall weather pattern suggests that storms will tend to strengthen quickly and overachieve not only in the East, but also over the Central states.
The problem is this for the storm in the East this weekend, we do yet not know exactly where the cutoff will be for accumulating snow versus a wintry mix versus all rain.
At this early stage, the most likely swath for heavy snow all, or in part, would be from Connecticut to central Massachusetts to southern New Hampshire. Finding a place to put the snow may be a problem. Where deep snow remains on roofs, the added weight of the new snow could lead to roof failures.
The New York City metro area appears to be near the southwestern edge of the snowstorm with all or mostly rain for Philadelphia to Washington, D.C.
However, where the storm develops and slows its forward speed could push the heavy snow area either farther west toward New Jersey and southeastern New York state, farther south and east over Long Island and Cape Cod or possibly even farther north and west over northern New England and eastern upstate New York.
This could be the type of storm where some locations are hit with a foot of heavy, wet snow and areas just 20 miles away have non-accumulating snow and rain or plain rain.
Additional big storms are in the making through next week, not only for the East, but also for central, southern and western parts of the nation.
