    An area of high pressure will crest over New England Friday, bringing hot and dry conditions across the region.

    High temperatures will reach into the upper 80s to 90 degrees inland and low 80s at the coast and the Cape and Islands, where an afternoon sea breeze is expected to develop.

    Humidity levels remain below uncomfortable levels. Overnight, clouds and humidity increase as a warm front crosses into the region. A quick-moving area of low pressure will bring the threat of showers and thunderstorms, especially along and north of the Massachusetts Turnpike.

    Lows will only drop into the 60s.

    A cold front moving in from the Great Lakes brings scattered showers and thunderstorms on Saturday. Right now, expect any severe weather that develops to be located south of the Massachusetts Turnpike during the afternoon and evening.

    In regards to timing, if the cold front slows down, all of New England is likely under the risk of severe weather. Primary threats will be damaging wind gusts and potentially-large hail with rotating storms. Highs on Saturday will be cooler than Friday, reaching into the low 80s south, mid to upper 70s across the North Country. Locales in the Connecticut River Valley may reach into the mid 80s.

    Leftover showers and moisture exit New England Saturday night behind the cold front. Sunday features renewed shower and thunderstorm threat as another weather system drops down into New England from Quebec.

    Expect the possibility of a few strong thunderstorms given instability and a cold pool of temperatures in the mid-levels of the atmosphere. High temperatures only reach into the mid-to-upper 70s across the south and upper 60s to 70 degrees north.

    Monday will feature sunny skies and a return of summer warmth as high pressure noses into New England. Highs rise into the mid to upper 80s, with sea breezes developing at the coast.

    A low pressure system will usher in scattered afternoon and evening showers and thunderstorms on Tuesday with highs reaching into the low-to-mid 80s. A sub-tropical ridge of high pressure builds into the Ohio River Valley, supporting a warm pattern into the middle of the week and into the Fourth of July.

    We’re keeping an eye on a couple of areas of disturbed weather that may impact holiday plans Wednesday and Thursday on the exclusive First Alert 10-Day Forecast on NBC10 Boston and necn.

    The exact timing remains uncertain but a chance exists for showers and a few thunderstorms late morning into the afternoon on the 4th with high temperatures reaching into the low to mid 80s south, low 80s across the North Country.
