A relatively weak system passes just south of New England early Monday morning resulting in a 1-3" snowfall across southern Maine (less to the north). Sunshine follows for a couple days, then all eyes focus on the potential for a big storm on the order of Thursday.
Low pressure will scoot just south of Long Island early Monday morning. An arm of low pressure -- a trough -- will extend from this low over southern Maine, touching off light snow that will linger through most of Monday morning. About an inch or two will be on the ground for the morning commute on Monday, which may slow things down a little on the roads. During the commute, there may be a quick burst (an hour?) of some moderate snow. WHen all is said and done around lunchtime, 2-3" of snow is likely for much of southwestern Maine, up through parts of the Midcoast. Farther up the coast, 1-2" is likely for Downeast. North of I-95, an inch is possible across central Maine. A dusting is possible as far north as the foothills with little or nothing toward the Canada border. After the snow winds down from west to east, a brief bit of sunshine is possible for Monday afternoon as the low departs.
Cold and tranquil weather follow for Tuesday and Wednesday. Meanwhile, here in the STORM CENTER, we'll be watching a couple pieces of "energy" as they travel into the western U.S. from the Pacific. Just how these two bits of energy interact will dictate how the end of the week pans out, weather wise.
At this point, most of the forecast data suggests at least some snow will occur on Thursday. However, there are also several indications that there may be a major coastal storm developing and riding up the Eastern Seaboard, if these pieces come together just right. We just can't be certain right now what will happen. I think the ingredients are certainly there for a big storm, but a lot of things need to come together just right for this to happen.
We, of course, will keep a close eye on things through the next couple days (and beyond).
