PHILADELPHIA (WPVI) --TODAY: It's another day of sunshine with low humidity, light winds and a warmer high of 87.
TONIGHT: Look for another clear night with a comfortable low around 68 in Philadelphia. Some suburbs will dip into the low 60s.
THURSDAY: A southerly flow bumps our temperature a couple of additional degrees and ups the humidity a bit, too. Look for a sun, a few clouds and a warm high of 89. An approaching cold front from the west could trigger a spotty thunderstorm late in the day or at night in our north and west suburbs, but most areas stay dry.
FRIDAY: A cold front arrives, but it's fairly weak. Ahead of it, temperatures climb into the 90s in most neighborhoods and dewpoints will jump back into the low 70s, making for a pretty sultry day. Spotty thunderstorms are possible, but we're not expecting widespread activity. Philadelphia's high is 93.
SATURDAY: That front does very little to drop temperatures, but the humidity will ease in its wake. Look for a partly sunny and hot start to the weekend with a not-too-sticky high of 91.
SUNDAY: It's a very warm afternoon with moderate humidity and a high of 91. If we indeed manage to hit 90 or better, this will mark our sixth heat wave of the year.
MONDAY: Clouds mix with sun. It's warm and very steamy, with a thunderstorm is possible at times. The high is 92.
TUESDAY: Look for mostly sunny skies and another warm high around 89.
