Warmth and the humidity continue to build this week with highs near 90 the next couple of days and dew points surging toward and above 70.
The storm threat is rather low again Tuesday, but gradually builds this week. A few storms may pop with the daytime heating Wednesday, but the areal coverage is limited, and the highest chance for those storms are outside 495. The higher storm threat for all of us is Thursday afternoon into Thursday night as a cold front approaches. The atmosphere will be loaded with moisture, so any thunderstorm will be capable of producing downpours. Of course, we could use the water as the lawns and gardens dry out fast this time of year, and will be parched by the time these storms make their way in. Also, we’ll watch for the potential of some of these storms to be feisty thanks to the high heat and humidity.
Unfortunately, it appears that the timing this front that’ll bring the storms along it, and the low humidity behind it, will be slow to move east. That means, we’ll have to leave the opportunity for scattered showers and storms in the forecast for the Fourth . There is a chance that we dry out and lower the humidity in the evening and overnight, but that’s still a bit uncertain as we have to see what happens to a tropical system off the Southeast U.S. coastline and how in interacts with our front.
At this point, the spin off the Florida coast likely becomes the first tropical storm, if not hurricane, over the next several days. The Carolina coastline, especially the Outer Banks, look to have the highest impact from this system. For us, the threat of a high impact event is low. The steering winds point from southwest to northeast, likely allowing the core of this system, to stay south and east of us. There is the potential that it’s close enough Friday night to keep showers around over eastern Mass, especially the Cape, but that remains to be seen. Even if Friday night stays wet across the Cape, this system quickly clears early Saturday, allowing for sunshine and lower humidity for the rest of the weekend. Although Saturday may be breezy still. In addition, we’ll watch for higher surf and the risk of rip currents at the shore next weekend. Especially the south and east facing beaches of the Cape and Islands.
We’ll keep you posted through the week. Stay cool!
