It's been another below-average temperature day, with highs staying in the low 60s (average: 74°). The mostly cloudy skies will continue into the overnight. Some areas could see some light showers, especially into the overnight. Lows will fall to the mid 50s.
Tomorrow will be mostly cloudy for the morning, but clouds begin gradually decreasing into the afternoon. The afternoon may actually mild with mostly sunny skies, however, the sunshine will act to destabilize the atmosphere as the cold front approaches. If the storms are able to initialize and fully realize the energy available, western Mass could see a round of strong to potentially severe thunderstorms between 4p-9p.
The main threats for these storms would be gusty, damaging winds and possibly moderate to large size hail. There is a pocket of very cold air above us, and if the thunderstorms grow large enough, the hail growth could be impressive. Rain totals from this system will be approximately .25-.5" in most areas, except where the thunderstorms persist. In those thunderstorms, you could see rain totals over an inch.
Thursday is looking like the pick of the week with lots of sunshine and temperatures in the mid-to-upper 70s. There is the possibility of some pop-up showers midday, but most of Thursday will be dry.
The month of June is rung in with comfortable conditions, but the longer range forecast looks a bit unsettled with at-or-below average temperatures for the first couple weeks of June. Much like the start of May, the same type of upper-level pattern will be around.
