Take Care Out There! Hot, Humid All Week

August 7, 2018

LOWELL -- Scorching temperatures expected to last through Tuesday evening have prompted the National Weather Service to issue a heat advisory for cities across the state, including Lowell and Fitchburg.

According to the advisory, the heat index (which combines air temperature and relative humidity) during this period will reach up to 103 degrees due to temperatures in the upper 80s to mid 90s, and dew points are in the lower to mid 70s. The heat advisory is in effect until Tuesday at 8 p.m.

National Weather Service Meteorologist Bill Simpson said residents to be careful with any outdoor physical activities.

“The sweating process is based upon evaporation of your sweat on the skin surface, which cools the skin surface. Once you get very high dew points and high temperatures, that process is not that efficient,” Simpson said Monday. “People don’t realize that a lot more people die from heat exhaustion than tornadoes and winter storms. It affects a much wider range of people. There’s widespread potential danger if you’re out working in the sun during the middle of the day. We like to focus on that.”

According to the weather service, Tuesday in Lowell is expected to have a high temperature near 97 with a slight chance of showers after 3 p.m. Wednesday is forecast to be partly sunny with a high near 90 and a chance of showers and thunderstorms mainly after 1 p.m. On Thursday, the weather service forecasts the area will remain partly sunny with a high near 86. Friday will also be sunny, with a high near 87.

“Today and tomorrow is the worst and then we get some minor relief off on Wednesday and Thursday,” Simpson said Monday of the combination of temperatures and dew points.

In Fitchburg, the weather service is forecasting a sunny Tuesday with a high near 94, as well as a chance of showers and thunderstorms between 2 p.m. and 5 p.m. The chance of showers and thunderstorms will remain until mainly after noon Wednesday. That day the high temperature will be near 87. The forecast for Thursday in Fitchburg is partly sunny with a high near 84 and a chance of showers before 11 a.m. Friday is expected to be mostly sunny with a high near 85.
