DAYS 1-5 (MAY 22-26)
Summer preview today. High pressure will have completed its journey from Canada to southeast of New England, and today the winds come around to mainly a land breeze (southwest), except along the South Coast and especially Cape Cod & the Islands where this wind is still off water. While many areas reach or exceed 80, some for the first time this season, those South Coast locations will not. Everybody turns much cooler Saturday as a frontal boundary drops down from the north and a bit of a squeeze play will be on between a new area of high pressure in eastern Canada and an old low pressure system which has been stuck to our west and south finally trying to make a run at southern New England. It will increase the cloud cover for a time tonight into Saturday and push some of its rain to about the South Coast, but it will really get no further than that before being pushed back to the south by the Canadian high, which will re-grain and retain control through the balance of the Memorial Day Weekend. Sunday will be the coolest day with a continued easterly air flow, which will then relax and turn more southerly on Monday as the high center, like its predecessor, slips to the southeast and will be located east of New England. This process will continue further by next Tuesday when it will feel a bit like summer again for a good portion of the region.
