PITTSBURGH — We kick off the start of summer with the hottest temperatures of the year on the way as a prolonged heat wave is expected to continue through the end of next week.
Temperatures will soar to the 90s starting Sunday afternoon with increasing humidity pushing heat index values up around 100 degrees and as high as 105 degrees in some locations through Wednesday. High pressure keeps us sunny and dry; the next chance for scattered thunderstorms may not arrive until late Wednesday or Thursday. So make sure to stay safe in the heat! Prepare now for this extended hot stretch. Make sure you have a place to stay cool out of the sun over the coming days, stay hydrated, keep pets cool and out of the sun and watch for heat stress.
