Friday will be mainly dry through the afternoon before a line of thunderstorms approaches in the evening. Some strong to severe storms are likely in interior New England, but the odds of severe storms reaching the coast of CT, most of RI and all of SE MA are lower. The air will be more stable near the coast overnight.
The weekend looks decent, with a warm Saturday and a cooler Sunday. Look for highs in the 70s on Saturday, but closer to 65 on Sunday.
A disturbance moving through the Northeast late in the weekend into Monday will bring rain back to Southern New England. Monday could be a washout with about an inch of rain possible between Sunday night and Monday night.
The system that will likely become TS Arthur will stay off the East Coast next week. The tropical or subtropical system will move into the open Atlanta Ocean by midweek.
A slow-moving area of low pressure that nudges Arthur out to sea will get stuck near the Eastern Seaboard next week. It’s exact position is uncertain, and the latest indications are that it will stay far enough south that the weather is dry in New England in the midweek.
The slow-moving storm system could bring rain back to New England by Wednesday night into Thursday, and showers are possible heading into next weekend as the disturbance very slowly drifts north.
It looks very cool in the early to middle part of next week with the rain on Monday and an onshore breeze Tuesday and Wednesday. When the stubborn weather system finally moves away late in the week, the temperature should jump into the 70s for at least part of the Memorial Day weekend.
