PHILADELPHIA (CBS) — The second day of September will much like the first: hot and steamy!

Yesterday’s high temperature of 95 degrees tied for the highest Philadelphia has seen all summer. After a foggy start, Wednesday won’t be too far off itself, again reaching the low 90s under a mix of sun and clouds. It will mark the fourth day of heat wave #5 for Philadelphia.

The heat and oppressive humidity will stick around one more day before things cool down just a bit in time for the holiday weekend. A weak cold front will trigger a few isolated thunderstorms, but it will also break the heat and humidity, paving the way for what looks to be a lovely Labor Day weekend.
