A warming trend begins Friday with temperatures in the low 90s through the weekend.

Northern areas of the country will increase in the mid 80s in Vermont and New Hampshire, mid 70s to low 80s in Maine. Humidity levels will be comfortable with dew points in the mid to upper 50s. Mostly sunny skies are expected on Friday, apart from erratic fair weather cumulus clouds.

A high brush fire threat is around Friday given low relative humidity levels and light westerly winds. Given the longevity of this summer’s drought, fine fuels are extremely dry and prone to ignition. Dry conditions continue through the night with high clouds filtering through the area. Lows will fall in the mid 50s to low 60s away from urban centers, where lows will only descend in the 60s above about 70 degrees.

Muggier air pours into New England on Saturday as the wind shifts from the southwest ahead of an approaching warm front. While another warm day in the upper 80s to low 90s is forecast, a developing sea breeze may keep areas along the coast cooler than inland areas.

Exactly where this sea breeze boundary sets in will determine the day’s high temperatures. Expect more cloud than Friday and the threat of an isolated shower or two. Sunday is another hot day with highs reaching the upper 80s to around 90 degrees. A mix of sun and cloud can be expected with cooler temperatures along the coast given an onshore wind component.

Looking ahead to next week, the next weather system will set in on Monday, kicking up a warm front to the north and triggering showers and thunderstorms across New England. Highs will only rise in the upper 70s to about 80 degrees given cloudy skies and shower activity. It will feel humid with dew points in the mid to upper 60s.

Showers and scattered thunderstorms are expected again on Tuesday, with highs reaching the 80s. The Bermuda High moves slightly westward midweek, bringing continued heat and humidity to the region. At this time, mostly dry days are expected, with the possibility of a few afternoon showers on First Alert’s exclusive 10-day weather forecast on NBC10 Boston and NECN.
