Boston has received appreciable rain three days this June - the rainfall total at Boston Logan is 1.22" as of early Tuesday (6/28) morning. Skies have also been sunny - 6 days have been clear, 16 have been partly cloudy and only 4 days were either mostly cloudy or overcast. Our rainfall deficit is 4 inches since January first.
For now, our dry, sunny stretch of weather is over. Showers and thunderstorms are likely through Wednesday. A few storms could be strong, especially in the Green Mountains and Berkshires today - tomorrow that threat will shift to the east.
If the sunshine is able to break through the cloudy skies --- we'll see fuel for these thunderstorms. Heavy rain and gusty winds are possible with the thunderstorms.
High pressure will build in for one day. We will end the month of June with sunshine, but with this progressive weather pattern, an isolated shower or thunderstorm is possible for Friday and Saturday.
A stronger high pressure system will build in for the remainder of the holiday weekend. Temperatures will range from the low to mid 80s for all three days of the weekend. Summertime heat and humidity will return by the middle of next week.
