The first half of the week is looking quite toasty, but the second half looks quite unsettled. There’s also the chance the first tropical depression of the season in the Atlantic could develop.

A ridge of high pressure will remain in place across the Eastern US to start the week, resulting in some very warm to hot and humid conditions. Temperatures will soar well into the 90s in many areas today with sunny skies, but a seabreeze will keep coastal areas a little cooler, mainly in the 80s. When you factor in dewpoints in the upper 60s and 70s, it’s going to feel like it is over 100 degrees outside, away from the coastline. Temperatures only drop into the 70s at night, setting us a brutally hot and humid day on Tuesday. Temperatures should be well into the 90s across much of the region, and it isn’t out of the question that a few places get close to 100 degrees. Again, with the humidity factored in, it will feel likely 100 to 110 once again. Wednesday is the transition day, as a weak backdoor cold front begins to drop down from the north. Inland areas will still be hot, likely topping 90 once again, but coastal areas may stay in the 80s as winds become onshore. A few showers or thunderstorms may accompany the front, bringing some relief from the heat.

That front should settle off to the south later Wednesday before stalling out, bringing an end to the heat and allowing much cooler air to settle into the region. As weak disturbances ride along the front, we’ll have episodes of showers and times between Thursday and Sunday. None of the days should be a washout, but it will definitely be cooler and wetter than the first half of the week, with temperatures likely below normal for the end of June. Sunday may actually turn out to be a decent day, with a lesser chance for showers and the potential for some milder temperatures.

Monday: Sunshine and a few clouds. High 90-97 inland, 82-89 along the coast, a little cooler across the Outer Cape.

Monday night: Mostly clear, a little patchy fog possible near the South Coast and Cape Cod. Low 69-76, a little cooler across Cape Cod.

Tuesday: Sunny, hot, and humid, just a slight chance for a late-day shower or thunderstorm. High 93-100, cooler across Cape Cod and the immediate South Coast.

Tuesday night: Clear skies. Low 71-78, cooler across Cape Cod.

Wednesday: A mix of sun and clouds, slight chance for a shower. High 87-94, cooler along the immediate coast and across Cape Cod.

Wednesday night: Becoming partly to mostly cloudy, chance for a few showers. Low 62-69.

Thursday: More clouds than sunshine with some showers possible. High 71-78.

Thursday night: Partly to mostly cloudy, chance for a shower. Low 57-64.

Friday: Mostly cloudy with some showers likely. High 68-75.

Saturday: Plenty of clouds, chance for more showers. High 71-78.

Sunday: Partly sunny, slight chance for a shower. High 75-82.

Meanwhile, in the tropics, there is the chance that our first tropical depression of the season could be forming. A weak area of low pressure has developed a few hundred miles east of Bermuda. It is generating some thunderstorms, and conditions are marginally favorable for a little development today, then conditions become a little more hostile after that. Given that we are past the average date of the first tropical storm in the Atlantic (June 20), and there hasn’t been anything even resembling an organized system yet, the folks at the National Hurricane Center are probably bouncing off the walls with nothing to do, so they’ll probably end up naming this, even though it’s not purely tropical and won’t be around for more than 12-24 hours.
