Weather Forecast Discussion

Comfortable and mostly sunny Wednesday!

Heat/humidity to return for holiday weekend

TONIGHT: Clear and comfortably cool. Low: 51

WEDNESDAY: Mostly sunny and very pleasant. High: 80

WEDNESDAY NIGHT: Clear to partly cloudy. Low: 58

As the axis of the upper-level low pressure (cool air aloft) pivots away from New England, high pressure will take control of our weather pattern. A stunning day is setting up for Wednesday with an abundance of sunshine and daytime high temperatures near 80 degrees. 

As that high pressure continues to slide south and east it will set up a typical "Bermuda high" pattern acting as a mechanism to pump warmer and more humid air up into our area. As a result, Thursday through the holiday weekend will start to make outdoor conditions increasingly uncomfortable. In addition, the heat and building humidity will create enough instability for a shower or thunderstorm each day.  

A cold front comes through the region late Saturday into Sunday allowing the warmth to ease. However, this frontal passage may lead to a more active weather patter with some showers and thunderstorms around at some point during the weekend. Once the front slides through, temperatures will ease a bit (as will humidity levels). Have a great Wednesday!
