Tornado Warnings Expire in Maine and NH; Serious Storm Threat Remains Across Region

The NBC10 Boston meteorologist issued a First alert on Monday for thunderstorms that will turn strong tonight.

Two tornado warnings have been issued by the National Weather Service late Monday into Tuesday, inside in Hampshire and southwestern Maine.

The tornado warning issued in Maine was in effect for Oxford, Cumberland, and York counties until 1:15 AM Tuesday. A serious thunderstorm that can assemble a tornado was located over Cornish around 12:38 AM, moving east at 40 mph. The severe storm was anticipated to be near Standish around 1 AM and Raymond around 1:15 AM.

A tornado warning was issued some hours before for Cheshire County in New Hampshire. The warning expired at 10:30 PM. The NWS remarked radar had directed rotation, and a serious thunderstorm that could produce a tornado was located 15 miles west of Kenee just after 10 PM.

Residents in areas were advised to seek shelter immediately while the warnings were active. The NWS reminded people that tornadoes are difficult to locate and confirm at night. There was no confirmation Monday night if a tornado had appeared in either state.

Serious wind and hail are a possibility, along with a brief tornado threat across Southern and western New England. Heavy rain can also accompany these storms, so there is a scope of urban floods, however, brief.

Heat Wave Expected

Tuesday marks the start of a heat wave for various locations. More highs in the 90s are forecast through the week with humid air, especially on Thursday. Heat index values may be in the 100-105 range Thursday so we have another First Alert for all. Temps are likely to stay hot through the weekend and beyond, “cooling” to the 80s for the rest of our 10-day forecast.
