An area of high pressure located over the Canadian Maritimes will bring renewed low clouds and fog across New England Friday.
Stubborn fog and low clouds will eventually give way to fair skies while an area of low pressure that brought rain showers and a few embedded thunderstorms exits through the North Country. Highs will range from the mid-to-upper 70s across the region.
There will be a renewed threat for rain showers and a thunderstorm mid-to-late afternoon in the White and Green Mountains. A building onshore flow allows fog to move back in overnight at the coasts with lows dropping into the low-to-mid 60s south and the upper 50s to 60 degrees across the North Country.
On Saturday, low clouds and fog will burn off, giving way to partial clearing by the middle of the day, with temperatures warming up into the upper 70s to the low 80s. Energy moving into the region from the Great Lakes may trigger a few showers across the Berkshires and higher terrain.
Summer heat returns on Sunday with a chance of showers in the morning as an area of low pressure skirts offshore to our south. We can expect dry conditions to prevail for most of the day.
High temperatures will reach into the mid-to-upper 80s to 90 degrees across New England, with Maine reaching into the mid-to-upper 70s to 80 degrees. Dew point temperatures rise to 65 to 70 degrees, making it feel very humid.
Looking ahead to the start of the work week, a potential heat wave continues to set up across New England. High temperatures will again crest into the upper 80s to low 90s on Monday as a southwest flow builds across the region. Heat indices will rise into the mid-90s.
Tuesday features almost carbon copy weather with hot and humid conditions well in place. An area of low pressure passing overhead will trigger scattered thunderstorms during the day.
By Wednesday, a cold front treks across New England, ushering in cooler and drier air from Canada and breaking the late-summer heat and humidity.
