Boston Weather: Greater Boston is set for another round of sticky, sweltering weather Friday, with forecasters warning of a slightly higher chance of passing storms before a picture-perfect weekend takes hold.

Boston slipped back into the 90s on Thursday. Humidity and dew points climbed steadily through the day. 


The tropical air made conditions feel uncomfortable across the region.


A few thunderstorms broke out over Northern New England Thursday afternoon. Boston, however, stayed dry overnight.


Friday Forecast: Heat, Humidity and Isolated Storms

Friday will bring even more heat and humidity to close out the work week. A slightly higher chance of a passing storm is also in the forecast for Boston.


Morning commuters can expect temperatures already in the 70s. Highs will climb into the upper 80s and low 90s later in the day. Skies will feature a mix of sun and clouds.


Dew points will stay elevated overnight, keeping conditions muggy from the start. 


Dew points are expected to range from the upper 60s into the 70s for most of the day. 


Heat index values will likely reach the low 90s across Greater Boston and areas to the west.


Cold Front May Trigger Spotty Storms

A cold front will sag across Boston and the Southern New England coast Friday afternoon. 


Scattered showers and thunderstorms are possible as the front moves through. 


Forecasters say the front's forcing is modest, so any storms that develop should not turn severe.


Boston residents could still get caught in a passing shower. Forecasters recommend carrying an umbrella, especially during the lunchtime hours and the evening commute.


Wildfire Smoke to Add Haze

Smoke drifting south from Canadian wildfires will create elevated haze across the region once again. 


Air quality alerts are not expected. The smoke could set the stage for vivid sunsets Friday evening.


Weekend Outlook: One of the Best of the Summer

High pressure will build across the region Saturday and Sunday. Forecasters say the pattern could deliver one of the best weekends of the summer.


Saturday will bring more sun than clouds across Boston and much of New England, with a little lingering haze. 


Highs will stay in the mid-80s, allowing residents to enjoy the warmth without excessive strain. 


Beachgoers can expect water temperatures in the upper 60s to low 70s.


Sunday should closely resemble Saturday. A mix of sun and clouds is expected as high pressure keeps the region dry. 


Highs will again reach the mid-80s across Greater Boston.
