BOSTON (CBS) – The last day of June is the last day of the heat wave. Wednesday comes with another round of 90s and even record temperatures. The record at Logan Airport for June 30th is currently 95 degrees. That was set back in 1945. In 2021 that will probably pass with 97 degrees in Boston!
Heat and humidity prepared the atmosphere for showers and storms. There may be some initial activity around 2pm, but the strongest storms are likely to happen between 6pm and 10pm.
The main threats from this fast-moving wave will be heavy rain and the potential of straight-line winds. Gusts of 40 to 60 mph are possible within the strongest cells. That would likely collapse branches and even full trees. Prepare for some Wednesday night power outages. Fortunately, this is after the hustle and bustle of the evening commute, so travel times shouldn’t be influenced too much.
Relief wants to arrive on Thursday, but a cold front is not exactly pushing through. The muggy conditions continue while the showers last until the afternoon.
The lower humidity finally comes on Friday when temperatures drop into the 60s! The cooler conditions persist on the 4th weekend of July.
