PITTSBURGH — (WPXI) – Temperatures are going in the wrong direction heading into the holiday weekend. And it will be soggy to start the weekend, too. You’ll need the sweatshirts and jackets Saturday. A big push of cool air will keep high temperatures in the upper 50s, more than 15° below the average high temperature for this time of the year. On and off showers will add to the dreariness. Sunday will still be cloudy and damp with isolated showers. It all pays off Memorial Day with a good deal of sunshine and highs back in the 70s.
