NEW ENGLAND — A significant weather threat is expected on Tuesday evening and overnight across northern New England as strong to severe thunderstorms develop over the region. Boston 25 Meteorologists are warning that storms could produce localized flooding, frequent lightning, damaging wind gusts, large hail, and even an isolated tornado.Storms are expected to develop later Tuesday afternoon across northern Vermont and northern New Hampshire before moving east into western Maine during the evening and overnight hours. While southern New England should remain mostly dry, an isolated shower or thunderstorm cannot be ruled out on Wednesday.The National Weather Service has also issued a Heat Advisory from 11 a.m. Tuesday through 8 p.m. Wednesday for Franklin, Worcester, Middlesex, Essex, Hampshire, Hampden, Norfolk, Suffolk, Bristol, Plymouth, and Providence counties.

Heat index values are expected to climb as high as 103 degrees, increasing the risk of heat-related illnesses for anyone spending extended periods outdoors.Adding to the unsettled weather, hazy skies caused by wildfire smoke will continue across the region Tuesday and are expected to become more noticeable on Wednesday.
