Warm temperatures linger through this evening with a haze to the sky thanks to the smoke from the Canadian wildfires. High pressure settles in overhead and the winds relax, with low humidity again and lows in the 50s to 60s in the suburbs.
Our humidity increases a bit as we head into Wednesday with more warm temperatures in the 80s to low 90s inland, low 80s at the coast with some seabreezes in the afternoon.
There is a slight chance for a pop up shower or storm across northern New England. Fog will be possible Wednesday night with the increased humidity levels.
Our dewpoints could be in the 60s to low 70s by Thursday afternoon as a tropical airmass moves in. A gusty south wind will bring in more heat too, with highs around 90 degrees. We may possibly have our third 90 degree day of the season in Boston.
A cold front will move through Thursday night through Friday, triggering scattered rain and thunderstorms. Lingering showers and storms will be possible along a shortwave Friday afternoon.
The humidity and rain will clear out in time for the weekend with both days in the mid to upper 80s and sunny. In our 10-day forecast, we expect more heat and humidity to return with a possible heat wave across the northeast.
