    (Published Monday, May 21, 2018)

    Today is about as close to New England perfection as the weather comes — dry air, abundant sunshine, and high temperatures in the 70s.

    With the fantastic weather comes a high UV index (don’t forget the sunscreen) and the air can dry the body out a bit, so hydration is important.

    In the North Country, a busy wind from the west-northwest increases brush fire danger with gusts over 30 mph, while the wind is lighter farther south, where an afternoon sea breeze may kick up right along the coast. As high pressure moves overhead, then east of New England, the door will open to moisture from the west, producing Monday showers in Chicago and set to bring increasing clouds to New England Monday night into Tuesday morning.

    Tuesday afternoon showers will last through Tuesday night, holding temperatures down a bit as a result.

    By Wednesday, sunshine returns and temperatures respond by rising back into the 70s. Although a quick shot of cool air is possible in eastern New England on a northeast wind Thursday, the general trend heading into the Memorial Day holiday weekend will be for warming — highs should reach the 80s Friday and Saturday! The only catch to this summery holiday forecast is the jet stream will be nearby. Keep in mind the jet stream is the fast river of air high in the sky that steers disturbances in the atmosphere — and this means an increased chance of showers and thunder.

    Saturday evening may bring some scattered storms, particularly in northern and western New England. Sunday will likely bring showers and storms with humid air, and Memorial Day has a 45 percent chance of showers lingering, according to our exclusive forecast system, so there’s still a chance the showers ship out in time.
