Hazy, hot and humid weather conditions continue across Pennsylvania, New Jersey and Delaware as the first heat wave of the season is expected to be declared tomorrow.
Friday is expected to be the hottest day of the early taste of summer.
Forecasters are predicting temperatures in the 90s across the area that will combine with humidity to make it feel like 95 degrees or hotter in some spots.
The normal high this time of year is in the high 70s -- not mid 90s.
It should be slightly cooler at the beaches, especially along the Jersey Shore.
NBC10 First Alert Weather meteorologist Brittney Shipp says that high ozone levels (a Code Orange Alert) could affect people who have trouble breathing.
Forecasters say the heat is expected to continue through Sunday. A heat wave will likely be declared Saturday after it becomes the third straight day with temps breaking the 90. There's a chance for strong to severe thunderstorms on Sunday night or Monday.
