It was an active day for Southern New England with a couple of rounds of thunderstorms. The strongest came through this morning with torrential rain and frequent lightning strikes in fact several maintenance workers were struck by lightning in Connecticut and there were a few structure fires in Massachusetts along with several reports of street flooding. Thankfully the second round that developed this afternoon wasn’t as fierce and has fallen apart now that the sun is setting.
The front that triggered the storms is sliding through and a wave of low pressure is developing along it in our coastal waters. That wave will slide east of us then slam into the Maine coast tomorrow. This will provide some steady rain to Maine tomorrow. We will be on the western flank of the storm…in it’s circulation…creating an unstable atmosphere and growing clouds and showers for the second half of the day. Some of the showers that develop may become t-storms and contain small hail.
With downstream blocking strengthening that same low will park itself over New England for several days…this means sunniest part of the day will be in the morning followed by growing clouds and scattered showers and storms each afternoon. By Friday, the trough in the Northeast will break down and this will allow heat to build back in…highs around 90 are likely over the weekend.
