Another round of thunderstorms threatens torrential rain Wednesday – NBC Boston

The same weather front that generated widespread thunderstorm activity, with heavy rain, lightning and wind damage last night, is only slowly moving south and east today.

The areas that suffered the worst weather last night and early this morning, in western and northern New England, are doing a little easier today.

Remnants of last night’s rain are now moving through Maine with welcome rain for the Crown region of Maine, where it has been fairly dry so far this month. But for most of us, we don’t need showers anymore, and yet they are coming back.

The overnight rain has cleared the smoke from the sky somewhat, but we still have a bit of haze with a mix of sun and cloud for a few hours this morning. It is less humid with a high temperature closer to 80 ° this afternoon. The wind is quite light and variable, apart from any thunderstorm.

Spot showers or thunderstorms are possible just about anywhere and anytime today, but it looks like we’ll have a more organized severe weather threat for Massachusetts, Connecticut, and Rhode Island after lunch.

Storms will kick in and then move east with possible wind gusts exceeding 55 miles per hour, torrential downpours and intense lightning. The threat appears greatest between 2 p.m. and 6 p.m. for southern New England.

After that we have high pressure on the Great Lakes which should push cleaner air into New England later tonight and tomorrow. By cleaner we mean less smoke, because the new air comes from eastern Canada instead of western Canada and the western United States.

It is a relatively cool air mass (for the peak summer heat).

The high average temperature in Boston begins to drop for the season tomorrow. Mother nature will comply with temperatures mainly in the 60s to 70s in the north and 70 to 80s in the south with good sunshine to start the day.

But there is a puddle of cool air up above, so we’ll see instability and cumulus clouds build up. There is a slight chance for a few showers and showers in the higher elevations of central and northern and New England. We have a north and northwest breeze at 10 to 20 mph, with lower humidity.


A warm front is approaching on Friday with increasing clouds and the likelihood of a few showers, possibly a thunderstorm, and high temperatures in the 1970s.

Another batch of relatively clean, low humidity air is expected to move on Saturday, with good sunshine and temperatures again in the 70s to nearly 80 degrees.

The clouds intensified on Sunday where we can end up rather gray with showers or thunderstorms possible. The timing is still tough, but it looks like Saturday should be the choice of the weekend.

Next week seems a little quieter than the past two weeks, but we still have a threat of afternoon thunderstorms every day with temperatures tending to be a little chilly for this time of year as we do. sees it in our first alert 10- day forecast.
