Unusual and intense heat and humidity have settled over the Middle Mississippi and Ohio Valleys and are expected to persist. The Heat Risk for much of the country is red, which is a major level of heat risk. There are even many areas of purple, which is the highest level of heat danger: Extreme. These locations need to limit time outdoors, stay hydrated, and check on your neighbors.

Southeast

Tampa, Florida, broke an all-time record high on Sunday, July 27th. Reaching 100° beats out the old record of 99° set on June 26, 2020. Tuesday, Tampa broke the all-time record for the highest heat index recorded by hitting 119°. When you're breaking all-time records in FLORIDA, that's how you know how hot it truly is.

Heat alerts continue across the Southeast, with Heat Risk levels at their highest in the country. Most of the southeast is at extreme Heat Risk through Wednesday afternoon, with heat index values still expected to be near 110°.

These conditions are particularly dangerous for vulnerable populations such as the elderly, children, outdoor workers, and those without access to reliable air conditioning or hydration. 

Mid South

Heat alerts are expected to continue across parts of the Gulf Coast and Mississippi River Valley. Just like parts of the Southeast, heat index values are going to climb to over dangerous levels near 115 degrees. There is likely to be some relief from the heat in these areas as thunderstorm chances increase mid-week.

Northeast

We even have heat advisories in the northeastern U.S, in particular, New England. Feels like temperatures here are likely to rise to 95-100°F through Wednesday before our next trough moves in.

Several records were broken on Tuesday, and there will likely be more records to add to the list before the day is over.

The heat index values will be in the triple digits for cities like Philadelphia and New York.
