DAYS 1-5 (SEPTEMBER 9-13)<\/p>\n\n\n\n
A slow-moving cold front moving west to east across the region will be the focus for showers and a few thunderstorms today into tonight, enhanced this afternoon and early evening by a wave of low pressure moving along it. Shower activity will be widespread, and while not every location will see the heaviest downpours, many will see some heavy rainfall for a time, and localized flooding may result – but not to the degree of recent events. Additionally, we have rough surf and large ocean swells (and resultant high rip current risk) from offshore Hurricane Larry ongoing today, which will also linger into the start of the weekend as the storm races by southeastern Canada on its way into the northern Atlantic. Meanwhile, we dry out overnight \/ early Friday as our low pressure wave and front pull offshore. Drier air moves in Friday as high pressure moves across the Great Lakes and Ohio Valley, but a weak trough moving through at upper levels supplies a pool of chilly air above us, and that results in some atmospheric instability, so when the sun heats the ground on Friday and works on the lingering moisture from today’s rainfall, we’ll see diurnal cloud development to prevent a totally sunny day, and some of those clouds may grow enough to produce a few isolated showers mainly in the afternoon. But with high pressure sliding to the south of the region and the upper levels warming, we have excellent timing for great late summer weather this upcoming weekend, both Saturday and Sunday, with the coolest part of the weekend being Saturday morning and Sunday the warmer of the 2 days. Another bubble of high pressure in eastern Canada will send a frontal boundary through the region early Monday with some clouds accompanying it, but right now it looks like we will miss any shower chance.<\/p>\n\n\n\n
TODAY: Mostly cloudy morning with showers\/thunderstorms moving out of eastern coastal MA and across Cape Cod through 8AM then numerous to widespread showers returning from southwest to northeast all areas mid morning through afternoon with embedded downpours and possible thunder.

DAYS 6-10 (SEPTEMBER 14-18)<\/p>\n\n\n\n
High pressure brings fair weather to the region September 14 into September 15 with a cooler start then warming up. Next frontal system brings shower chances late September 15 to early September 16 followed by fair, drier and slightly cooler weather into September 17 before it warms up again at the end of the period.<\/p>\n\n\n\n
DAYS 11-15 (SEPTEMBER 19-23)<\/p>\n\n\n\n
A weaker west to east flow pattern is expected but this may allow low pressure to the south of the region to get a little closer with some cloudiness and possible shower chances early in the period. Another disturbance from the west may bring showers followed by a late period cool-down, but this is lower confidence at this time.<\/p>\n","protected":false},"excerpt":{"rendered":"
