92 was the high today in Boston, missing the record by 5 degrees but making it the first official heatwave of the year and the first since last July.  Once again this evening, due to the heat and humidity, thunderstorms have erupted…tonight’s aren’t as widespread or fierce but we are keeping our eyes on them.

Following their departure the air will remain very stuffy and overnight lows will only drop down to around 70.  Tomorrow will start out just like the last several but with a coldfront approaching from the west, clouds and thunderstorms will be present earlier in the day.  The result, a stormy afternoon but less heat…highs will stay in the 80s ending the heatwave.

Thursday will be even cooler, the heat will attempt to build back in behind a warmfront but the front looks like it will get hung up to our south.  Winds will stay more or less onshore…yes very muggy but not very hot…in fact, most towns will stay in the 70s!  With the warmfront close by there will be the threat for dangerous thunderstorms especially in the afternoon.

Friday through the upcoming weekend will be very similar days. Very muggy and humid flow will be coming up from the south at the same time, a cold pool of air will be digging in from the west…this will create an unstable atmosphere and with a little added sunshine that’s a recipe for soaking thunderstorms especially in the afternoons.
