Another round of thunderstorms threatens torrential rains on Wednesday – NBC Boston

The same weather front that caused widespread thunderstorm activity last night with heavy rains, lightning strikes and wind damage is only slowly pushing south and east today.

Areas that had the worst weather last night and this morning, in west and north New England, are a little easier today.

The remnants of last night’s rain are now pushing through Maine with welcome rain for the Crown of Maine area, which has been fairly dry this month so far. But for most of us we don’t need any more downpours, but here they come again.

The overnight rain cleared the smoke from the sky, but we still have a few hours of haze this morning with a mixture of sun and clouds. It is less humid with a high temperature close to 80 ° this afternoon. The wind is quite weak and variable, outside of thunderstorms.

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

Storms will flare up and then head east, with possible gusts of wind in excess of 55 miles per hour, torrential rain, and intense lightning. The threat looks greatest to southern New England between 2 p.m. and 6 p.m.

After that we have high pressure over the Great Lakes, which should bring cleaner air to New England tonight and tomorrow. By cleaner, we mean less smoky, as the new air is coming from eastern Canada rather than western Canada and the western United States.

It’s a relatively cool mass of air (for the height of the summer heat).

The average high temperature in Boston is starting to drop for the season tomorrow. Mother Nature will mostly hold the temperatures in the 60s to low 70s in the north and 70s to low 80s in the south with a good amount of sunshine to start the day.

But there is a cool pool of air in the air so we’ll see instability and cumulus develop. In the higher elevations of Central, Northern and New England, there is little chance of some showers and splashes. We have a north-northwest breeze at 10 to 20 miles per hour, with less humidity.

A warm front is approaching on Friday with increasing clouds and the possibility of some showers, possibly a thunderstorm and high temperatures in the 70s.

Another batch of relatively clean, low-humidity air should be hovering close to 80 ° on Saturday with a good amount of sunshine and 70s temperatures.

The clouds increase on Sunday when we end up gray with possible showers or thunderstorms. The timing is still tough, but it looks like Saturday should be the weekend’s pick.

The next week looks a little quieter than the past few weeks, but we still face the risk of some afternoon thunderstorms each day with temperatures that tend to be a bit chilly for this time of year, as seen in our first Alarm 10. Daily forecast.
