Boston, MA – A wave of oppressive heat is set to descend on the Boston area for Juneteenth, with heat index values expected to touch 100 degrees. The dramatic shift follows a period of scattered showers expected to conclude by late Wednesday morning, giving residents a brief window to prepare for the potentially dangerous temperatures arriving Thursday.
According to the National Weather Service, the most intense heat will build throughout the day on Juneteenth. Highs will reach the mid-90s, but the humidity will make it feel closer to 100°F. Residents should take precautions against heat-related illness. Stay hydrated, seek air-conditioning, and limit strenuous outdoor activities, especially during peak afternoon hours. Check on relatives and neighbors who may be vulnerable to the extreme temperatures.
The heat brings an increased risk of thunderstorms. A slight chance of showers and thunderstorms is noted for Thursday evening, primarily between 8 p.m. and 2 a.m. These storms could bring gusty winds, so securing loose outdoor objects is advised before the heat sets in.
Cooler, more comfortable conditions will return for the end of the workweek. Friday is expected to be mostly clear with a high near 82 degrees, offering a reprieve from the humidity. The pleasant weather will extend through the weekend, with sunny skies and highs in the mid-80s on Saturday and Sunday.
Looking ahead to early next week, partly cloudy skies and seasonable temperatures are anticipated to continue. Warnings for the Juneteenth heat remain the most pressing concern, and residents should monitor for any potential heat advisories issued by officials.
