News Summary

Boston is currently under a heat advisory as temperatures approach 90 degrees, with high humidity making it feel even hotter. This weather pattern is accompanied by smoke from Canadian wildfires and forecasts of severe storms later in the week. Residents are urged to stay hydrated and limit outdoor activities during peak heat. A cold front is expected to bring relief with cooler temperatures by Thursday. Thunderstorms may develop on Friday, particularly in southern regions, but more pleasant weather is predicted for the weekend.

Boston Faces Heat Wave with High Humidity and Severe Storm Risk Through Week

A heat advisory is currently in effect for the Boston area, lasting through Wednesday. Temperatures are projected to climb near 90 degrees Fahrenheit for Boston and inland Massachusetts on Monday, while coastal regions will see temperatures around 87 degrees. The National Weather Service (NWS) reports that high humidity levels will cause heat index values to feel as high as the mid-to-upper 90s, with some areas even approaching 100 degrees.

Week’s Hottest Days Ahead

According to meteorologist Emily McMinn, overnight temperatures will drop only to the low 70s, which could hinder cooling off during the night. Monday night may feature light winds and lows in the 60s to near 70, along with potential low fog.

In addition to the rising temperatures, smoke from Canadian wildfires may cause hazy conditions in the area; however, the worst of the smoke is expected to remain north of the Boston region. Moving into Tuesday, forecasters expect peak temperatures to reach the mid-90s, making Monday and Tuesday the hottest days of the week.

Cooling Relief on the Horizon

A cold front moving through the area could lead to cooler temperatures and rain later in the week. By Thursday, temperatures are anticipated to drop to the low 70s with significantly reduced humidity, with dew points likely falling to the mid-50s. The weekend forecast suggests typical summertime weather for Boston, with temperatures expected to remain between 80 and 85 degrees.

Severe Storm Risks on Friday

As the week progresses, the NWS has updated its forecast to indicate that Friday will present another hot day, with temperatures in the mid-to-upper 90s. Dewpoints on Friday are expected to reach near 70 degrees, amplifying the heat. A cold front is projected to move through Massachusetts on Friday afternoon, bringing with it a risk of thunderstorms, some possibly severe. Areas particularly from Worcester County southward will face a “slight” risk (level 2) for severe storms.

Thunderstorms are expected to develop between 2 p.m. and 8 p.m. on Friday, with potential hazards including heavy downpours, damaging winds, and small hail. Following these storms, forecasters predict a transition to cooler and drier air, leading to more pleasant conditions on Saturday.

Weekend Weather Outlook

While cooler conditions are anticipated post-storm, light showers may return on Sunday. However, no significant interruptions to outdoor plans are expected. Throughout the week leading to the weekend, southern New Hampshire and various regions including Central/Western Massachusetts and Rhode Island will also likely experience warm days filled with sunshine and high humidity.

July Conclusion Forecast

The end of July is projected to conclude warmer and slightly drier than average, with an ongoing rainfall deficit when compared to historical trends. This extended heat wave is characterized by three or more consecutive days of high temperatures reaching at least 90 degrees. Residents are advised to stay hydrated, avoid prolonged outdoor exposure during peak heat hours, and monitor weather updates as conditions evolve.
