It's not just the temperature this weekend that'll be sizzling.

A full-blown heatwave will blanket the region through Monday with highs approaching 100 degrees coupled with oppressive humidity.

So keeping cool may take a little work.

But dozens of events - a live-music fests on the Delaware River Waterfront, an international cycling championship and an ethnic street festival - will provide a distraction from the summertime swelter.

ALL WEEKEND

North America's most prestigious cycling contest rolls into Philadelphia this afternoon with three-days of parades, picnics, and family biking activities that'll culminate Sunday with the 24th Commerce Bank Philadelphia International Championship and Liberty Classic.

More than 200 of the world's top pro cyclists race at 9 a.m. Sunday on the Benjamin Franklin Parkway, competing for more than $90,000 in prize money.
