We are on a streak of beautiful Monday and Tuesdays and it’s going to continue this week with another beauty on Tuesday.
With high pressure from Canada dominating, we have plenty of sunshine in the morning. Temperatures will rise quickly into the 80s to nearly 90 degrees in the afternoon when a layer of mostly thin clouds will dim the sun.
The clouds on Tuesday are associated with a warm front which will pass during the evening and Wednesday. That means that we get on the more humid side of the front, with temperatures approaching 90 to 95 degrees Wednesday. Humidity will climb to a very uncomfortable level with dew points in the 70s in parts of southern and western New England.
A trailing cold front in the Midwest will gradually merge with the remnants of Tropical Storm Barry to produce showers and thunderstorms Wednesday afternoon.
Heavy showers and thunderstorms Wednesday night may cause spotty flash flooding overnight and into the start of Thursday, similar to what happened last Thursday and Friday. The wind is going to shift and come in from the north in much of New England Thursday, with cooler temperatures, but continued high humidity.
With the clouds and showers Thursday, we may not make 90 degrees but a lot of us should be in the 80s, though 70s are possible where it stays cloudy in parts of central and northern New England. Also, low clouds and fog may move in off the ocean and not break during the day.
High pressure moving across southeastern Canada will push east, allowing a return of a warm front on Friday. That means a return to partly sunny skies with a chance of a thunderstorm, back close to 90 degrees by afternoon. Midsummer high pressure builds to the south of New England this weekend, meaning the wind from the west with some of the hottest weather so far this year.

Temperatures will likely be in the 90s Saturday and Sunday. There is a front close enough to cause some scattered showers or a thunderstorm, but most of the weekend should be rain free, but very hot and humid.
