To many of you, March Madness started this past weekend, and by now, your bracket is busted. For some of you, March Madness has been going on for a couple of weeks, and you’ve got trees and other things that are busted. Will the Madness continue? It looks like it may, for at least part of the region.

The week starts off with high pressure in control, so we have another dry but chilly day for Monday. Clouds start to stream in on Tuesday as low pressure moves off the Mid-Atlantic coastline. Unlike most of the storms that have impacted us this month, this storm should slide off to our south, with little to no impact on New England this time. However, another storm quickly follows behind that one, and this one should be a bit farther north and west, meaning that at least parts of the region will see some impact. There is still many questions about the exact track this storm will take and how strong it will be, so we’ll likely have a special post later in the week about it, but for now, we have some preliminary ideas.

It looks like a period of light snow is expected from Wednesday morning into Thursday morning across the area. The snow is most likely across southeastern Massachusetts, but could extend as far inland as southern New Hampshire and central Massachusetts. There’s also the chance that some rain could mix in across Cape Cod. These are the type of details we won’t be able to resolve until sometime on Tuesday most likely. One thing we are fairly certain of is that another period of strong winds is likely across eastern Massachusetts, especially along the coast. Tides are astronomically high again this week, so coastal flooding will be a concern at high tide, especially the high tides early Wednesday and Thursday morning, as well as Wednesday afternoon.

The storm starts to pull away Thursday afternoon, but with an upper-level low pressure system moving through, plenty of clouds are likely into Friday, with a few flurries possible. High pressure briefly builds in for Saturday with some sunshine, but clouds quickly return in the afternoon as the next system starts to approach. As for that system on Sunday, the usual caveats apply – it’s seven days away, there’s a ton of uncertainty, things can and will change, yadda, yadda, yadda.

Monday: Sunshine and a few clouds. High 32-39.

Monday night: Clear in the evening, then high clouds start to stream in late at night. Low 14-21.

Tuesday: Thickening clouds. High 33-40.

Tuesday night: Mostly cloudy and becoming breezy. Chance for light snow towards daybreak along the south coast. Low 21-28.

Wednesday: Cloudy and breezy with light snow likely, possibly mixing with rain across Cape Cod. High 30-37.

Thursday: Light snow ending early, a few sunny breaks may develop in the afternoon, still breezy. High 37-44.

Friday: More clouds than sunshine, chance for a flurry. High 38-45.

Saturday: Sunny to start, clouds return in the afternoon. High 37-44.

Sunday: Mostly cloudy and breezy with a chance of snow or rain. High 32-39.
