Stormy Skies in Northern New England

New Englanders started Monday off with some fog along the coast, especially dense for the Cape and the Islands. However, the big story today is the severe weather for northern New England.

A severe thunderstorm watch was issued for 10 counties in central Vermont and for parts of New Hampshire until 8 p.m. this evening.

A severe thunderstorm watch means storms are possible in that area, and if a severe thunderstorm warning is issued, that means you need to take action to get to a safer location. A line of strong to severe thunderstorms are expected to sweep across in a line from northwest Maine, to northern New Hampshire, to central Vermont through 5:30 p.m., and continue to slide eastward through 9 p.m. The main threats with these thunderstorms are torrential rainfall impacting visibility, damaging winds, large hail, frequent lightning and flash flooding.

After 9 p.m., these storms are expected to weaken as they do not have the daytime heating that fuels them. For southern New England, these showers/thunderstorms are expected to reach as far south as Laconia, New Hampshire, so it looks like the Fenway forecast for this evening’s Red Sox game against the Blue Jays will be dry and pleasant with temperatures into the upper 70s by first pitch.

Areas of patchy dense fog are possible overnight, with lows into the 60s, 70s in Connecticut. Tuesday, the humidity continues to crank, with the potential for more thunderstorms tomorrow afternoon for a wider swath of the area, including Maine, New Hampshire, most of Massachusetts, and Connecticut. These will continue into the evening commute, before they too, fizzle around sunset. Highs Tuesday are expected into the mid 80s.

Wednesday and Thursday are the days that bring on the heat and humidity from the southwest, with some locations expected to reach into the 90s both days. A cold front slides in late Thursday into early Friday, ushering in a slight cool down Friday, and closer to seasonal normal by the weekend. Saturday and Sunday are expected to be gorgeous with highs into the lower 80s and mostly dry with a chance for storms late Sunday into next Monday.
