If we had written this forecast a few days ago, it would have looked rather cool and damp for a large chunk of the week. Instead, it’s now looking a lot drier, and likely a bit milder, especially late in the week.
We start the week off with a warm front trying to move into the region, producing a few light showers this morning , mainly north of the Mass Pike. The front won’t quite make it, so we’ll remain on the cool side, with plenty of clouds. The reason the front won’t make it is a large area of high pressure over eastern Quebec is going to slowly build in and drop southward. As the high builds in, we’ll start to clear out for Tuesday, with another cool day expected, especially along the coast.
As we had into the middle to latter portions of the week, that high pressure area will continue to slide southward and offshore, with winds shifting into the west and southwest. This will bring milder air back in, especially by Friday, when temperatures could top 80 degrees in spots.
By Friday night, a weak area of low pressure over the Mid-Atlantic states will start to push offshore south of New England. This will bring clouds back in along with a few showers. The more noticeable effect will be on temperatures, as winds will shift back into the east, bringing much cooler air back in off the chilly Atlantic. We’ll dry out Saturday night and Sunday as the low pulls away. High pressure should build back in for Memorial Day, with warmer weather returning.
Monday: Plenty of clouds, chance for a few showers in the morning, mainly north of the Mass Pike. High 60-67, cooler along the coast.
Monday night: Partly to mostly cloudy. Low 41-48.
Tuesday: A mix of sun and clouds, breezy. High 55-62, coolest along the coast.

Thursday: Sunshine and a few afternoon clouds. High 67-74, cooler along the South Coast.
Friday: Partly to mostly sunny. High 73-80, cooler along the South Coast.
Saturday: Intervals of clouds and sunshine, breezy, chance for a few showers. High 68-75, but temperatures may turn cooler in the afternoon, especially along the coast.
Sunday: Partly sunny. High 63-70, cooler along the coast.
Memorial Day: A mix of sun and clouds. High 70-77, cooler along the coast.
Tropical Storm Arthur remains fairly weak off the Southeast coast early this morning. It will brush the Outer Banks of North Carolina later today with some gusty winds and heavy rainfall, but is expected to turn more toward the northeast and east and head out to sea while becoming extratropical on Tuesday. It may bring some gusty winds and rainfall to Bermuda later this week as an extra tropical system. After that, it may actually meander around in the central Atlantic for several days as an extratropical system, but won’t impact any land areas.
