Another very hot and humid day is in store for the entire viewing area on Saturday.  Expect temperatures to be in mid 80's with a heat index in the 90's.   Dry air from the northwest will slowly push in later on in the afternoon and that will set off wide spread downpours and thunderstorms across the area.  Some of the storms could be strong to severe as we head into the early evening hours.   A chance of showers on Sunday but comfortable as lower dew points make it feel more like the 80's in Pennsylvania...not Florida.
