ORIGINAL STORY

The heat wave will continue through the rest of the week with highs expected to be in the 90s at least through Saturday. The heat index will be close to 100 degrees every afternoon. A Heat Advisory remains in effect through Friday evening for several counties.

On Tuesday, the National Weather Service issued an Excessive Heat Warning for Beaver, Fayette, Washington, Allegheny, Butler and Westmoreland Counties until Friday evening. NWS says there could be maximum heat incides of 105-110 degrees. Temperatures in these counties will only drop to around 70-75 degrees at night.

Showers and storms are possible this afternoon through the early evening. The storms could become severe and produce damaging winds that could knock out power, and heavy rainfall that could lead to flash flooding, frequent lightning and hail. It’ll be very warm and humid overnight — temperatures will only fall to the low to mid-70s.

Make sure to be prepared and find ways to keep you and your family cool, watch for signs of heat-related illnesses during this hot stretch. Make sure to stay out of the sun, stay in air-conditioning, keep hydrated, and keep pets out of the heat.
