~Isaias made landfall around 11:10pm Tuesday night near Ocean Isle Beach in North Carolina as a Category 1 hurricane with sustained wind of 85mph.
A few showers and a thunderstorm are possible overnight along with increasing clouds and humidity. Overnight lows fall into the upper 60s to near 70 with a light breeze.
Tuesday begins warm and very humid with a chance for showers. Scattered rain is likely on and off throughout the day along with an occasional thunderstorm in the afternoon. A few storms may be severe in the afternoon as well. Temperatures hold in the 70s for most with increasing wind into the evening.
Details: The track of Isaias has trended a bit farther West, meaning our forecast changes a bit. For the Pioneer Valley, wind may be a bit stronger with sustained wind rising to 25-35mph and gusts reaching 50mph by Tuesday evening and night as the storm approaches. Rainfall amounts look a bit lighter with the valley getting a half inch to 2 inches of rain, while Berkshire County may see 2-4 inches with isolated higher amounts. Flash flooding will be possible for everyone, due to the threat of imbedded thunderstorms, which would bring isolated higher amounts of rain.
A tornado threat is also a concern for Tuesday afternoon and evening on the eastern side of the tropical storm, which includes most of southern New England.
Overall, the brunt of the storm will impact western Mass Tuesday evening and early night, with conditions improving overnight. The storm will be well out of our area by sunrise Wednesday!
The remainder of the week looks to be dominated by high pressure, which will give us good sunshine, lower humidity and light breezes. Temperatures in the lower to middle 80s are on tap to end the week, then we turn warmer over the weekend.
