We are in the middle of what will be the longest and most intense Heat Wave of the summer. The high temperature Wednesday was just 90 degrees, but the mercury will soar much higher than that during the next few days.

An Excessive Heat Warning is in effect for the entire region until 8PM Saturday. That means it is going to be dangerous to be outdoors for an extended period of time. With high humidity, Heat Index values will be between 105-110°. Please take precautions to avoid heat stress. Drink plenty of water and stay in cool places.

Friday afternoon will be the worst of it when the actual temperature climbs to 101 degrees. This will break the record of 100° for the day last reached in 1957. We also have a chance to tie or break the record on Saturday with a forecasted high of 99 degrees. That record, of 99, was last set in 1991.

You may remember last summer as being one of the hottest ever with 55 days at or above 90 degrees. Last summer we also experienced back to back triple digit temperatures in early July but during the last 12 years we only reached 100° or higher 5 times in Philadelphia. With our current forecast, it looks like we will adding at least one more to the list.

If you need assitance during the heat you can call the Philadelphia Heatline at 215.765.9040. This number will remain active until July 23rd.
