Tuesday likely marked the first day of 2017's third heat wave. The mercury reached 90F at Bradley Airport and we're expecting several additional days at or above 90. Today also was our ninth 90 degree day of 2017.
It's a pretty classic setup with a Bermuda High allowing warmth to move in from the west as the jet stream retreats into Canada.
It doesn't look like the warmth will stick around for too much longer as another dip in the jet stream and cooler weather moved back for the weekend. At this point a round of showers and thunderstorms appears likely for a portion of the weekend ahead of our next jet stream disturbance. Stay tuned for more specifics.
