Southern New England is under a Weather Alert as dangerous heat and humidity continue through Wednesday. A strengthening ridge of high pressure, often called a heat dome, is expanding over the Northeast while a steady southwest wind pumps a surge of hot air into the region. Afternoon high temperatures are expected to climb into the mid to upper 90s away from the immediate coastline, while dew points rise into the upper 60s and low 70s. Together, this will push heat index values into the mid 90s to near 100 degrees, making it feel significantly hotter than the actual air temperature. Southwest winds will also become gusty this afternoon, with gusts between 25 and 30 mph. While the breeze won’t provide much relief from the heat, it will help keep the humidity from becoming quite as oppressive as it was during the early July heat wave.
Heat Alert
The dangerous combination of heat and humidity has prompted the National Weather Service to issue Heat Advisories for all of Rhode Island, much of Connecticut, and portions of Massachusetts. The advisories remain in effect from 11 a.m. Tuesday through 8 p.m. Wednesday. With heat index values approaching 100 degrees, the risk of heat-related illnesses increases significantly, especially for anyone spending extended periods outdoors. Drink plenty of water, take frequent breaks in air-conditioned spaces, and limit strenuous outdoor activities during the hottest part of the day.
Air Quality Alert
An Air Quality Alert is also in effect Tuesday from 11 a.m. to 11 p.m. for Rhode Island and portions of Massachusetts. Smoke from Canadian wildfires will create hazy skies, while hot temperatures and abundant sunshine help produce elevated levels of ground-level ozone. Air quality may reach unhealthy levels for sensitive groups, including children, older adults, and those with asthma or other respiratory conditions. If you’re sensitive to poor air quality, consider limiting prolonged outdoor activity during the afternoon and evening.
