We are finishing up our tenth day in a row with no measurable rain to say it’s dry out there is an understatement. While our weather continues to impress we are now only two days away from getting some much-needed rain.
High pressure is still in charge of our region as it sits just offshore. We’ve seen light onshore flow through the day and that has increased the low-level moisture. This has led to low clouds and fog near parts of the coastline. We saw the clouds this morning and it took a few hours to burn off…I expect the same tomorrow morning…in fact, there’s a Dense Fog Advisory in place for SE MA through early tomorrow morning. After the fog burns off, it will be all sunshine and very warm temps too…we will range from 75-80 inland to 65-70 at the coast.
Wednesday will start dry but raindrops will spread in from the south by the end of the day as a warmfront, extending out from an area of low pressure, swings into the Northeast. There will be a pretty good fetch of moist air flowing into Southern New England and within the line of showers there will be some downpours…a solid soaking is in the cards right now. The line of showers and downpours will lift north of us Wednesday night but unsettled weather will stick around on Thursday too. The mid-level low will pass overhead during the day…this is a cool pool of air and will instability…scattered showers and potential pop-up thunderstorms during the day especially in the afternoon.
The trough will lift out offering up a dry Friday but another trough will dig in over the weekend. While Saturday will start dry, it doesn’t look like it end dry…showers will once again return during the afternoon and some steadier rain will be possible Saturday night. Mother’s Day won’t be perfect but it should be better than Saturday afternoon. A coldfront will slowly work through so scattered showers will once again be possible.
