Thunderstorms move west to east across New England – NBC Boston


Our first alarm continues for a slow moving thunderstorm line. The line marches west to east across New England all Friday. The persistent threat of storms also continues.

Harmful wind and heavy rain will be the main threats of any storm. A short spin-up tornado is also possible, but the risk remains low.

The question will be how much sunshine can be seen in central and east New England this afternoon. The more sun, the more instability and that is the fuel for the persistent storms. If we stay cloudy we can suppress all widespread harmful storms.

Our temperatures stay warm with maximum values ​​of almost 80 degrees and high humidity, so that every shower leads to heavy rain; 1-2 inches of rain is possible in the west, with about half an inch in the east.

The storms can fizzle out a bit and the line is heading for Boston in the late afternoon and evening this afternoon. The storms and showers remain in the forecast until sunset. But after the sun goes down, the atmosphere stabilizes more and the severe weather threat is over.

Unfortunately, this system will only leave the Northeast slowly. From Saturday morning to afternoon we keep showers in the forecast, with the individual cells moving from south to north. If the front moves out earlier, the second half of Saturday will dry up and the sun will reappear from west to east. However, with the latest model updates, the front remains near eastern New England, so eastern areas still have a chance of rain.

Highlights Saturday will be in the mid-70s, we stay humid in the east, less humid in the west. On Sunday the upper low is still northwest of us and could turn in a frontal limit. This will bring more showers, especially in the north. Highs will be again in the 1970s.

We are drying for the start of the next week, as high pressure builds up and drier air takes over. During the week there is a chance that the humidity will return for a short time. One system will bring in isolated rain for the end of the week, and then a bigger cool down could be imminent when we see highs in the 1960s.
