Showers & Thunderstorms With Small Hail Expected This Afternoon & This Evening: An upper level low pressure system now located over western Pennsylvania will rotate across the region this afternoon. This weather system will bring with it an abundance of unstable air. Because of this, I expected quite a bit in the way of shower activity along with some isolated thunderstorms. Small hail may occur with the strongest of the shower and thunderstorm activity. Showers are likely to begin developing across the region by about 2 pm this afternoon and become fairly widespread in coverage by about 4 pm with isolated thunderstorms also a possibility. Two things might happen with the most robust shower and thunderstorm activity between 4 pm this afternoon and 11 pm this evening. The first is that the more robust shower activity may produce small hail. The second is that these much more robust showers may take advantage of the very cold air aloft to cause the rain to change to snow as it falls, especially in the Worcester Hills and the Berkshires. All-in-all, it looks like it could be quite a wild late afternoon and evening across the entire area. Needless to say, I’ll be keeping an eye on the activity and will update you as needed. All shower activity will push out of the area by about midnight tonight. Temperatures this afternoon will be around 50 Degrees. Low temperatures tonight will be near 35 Degrees. Winds this afternoon will be southwest at 7 to 15 mph. Winds tonight will be west at 7 to 15 mph.
