The heat index value is 103. What you should know
The heat index – what is it and how is it calculated?
Heat is one of the leading causes of weather-related deaths in the United States. Hundreds of people die from heat each year, and heat-related illnesses increase even more.

A heat warning is in effect for southern New England from 8:00 a.m. Monday to 8:00 p.m. Wednesday.
Temperatures are expected to reach 93 degrees Fahrenheit (34.4 degrees Celsius) and, combined with high humidity, could cause heat-related illness, the National Weather Service’s Norton office warned.
The heat index value, which takes humidity into account, could reach a scorching 40 degrees today.
“Dangerous heat and humidity are forecast for our region from today through Wednesday, with the possibility of mainly afternoon and evening thunderstorms each day and especially late Wednesday into Wednesday night,” the meteorologists said in the discussion. “A cold frontal passage late Wednesday into Thursday will give way to a much more pleasant air mass by the end of this work week.”
Where does the heat warning apply?
The counties affected are Southern Worcester, Central Middlesex, Northern Middlesex, Southeast Middlesex, Suffolk, Eastern Essex, Western Essex, Eastern Franklin, Eastern Hampden and Eastern Hampshire.
How to stay safe
The NWS recommends staying hydrated and making sure people have access to air conditioning, an NWS spokesperson said.
Take special precautions when outdoors. Wear light, loose-fitting clothing. Try to limit strenuous activities to the early morning or evening. Take action if you notice symptoms of heat exhaustion and heat stroke.
Is this a record?
There’s a chance Worcester could break a record today, the NWS spokesman said. The highest temperature ever recorded for today was 90 degrees in 1892 and will be surpassed if the forecast stays at 93 degrees as expected.
Forecast for Worcester: A slight chance of rain between noon and 1 p.m., then a chance of rain and thunderstorms. Mostly sunny, with a high around 93. Southwest wind 6 to 10 mph, with gusts as high as 22 mph. A 40% chance of precipitation. Nine precipitation amounts between 1/2 and 1/4 inch, but heavier amounts are possible in thunderstorms.
