Here's your daily look at five stories to know about:

1. Same-sex marriage in Pa.: The Philadelphia suburbs are again in the spotlight about gay marriage. Montgomery County's register of wills began issuing marriage licenses to same-sex couples earlier this summer, prompting a lawsuit by the Corbett administration and pushing the state to forefront of legal battles over gay weddings. Now, Larry Keller, the mayor of New Hope in Bucks County -- long-known as one of the region's most LGBT-friendly towns -- is taking heat for declining to officiate a same-sex wedding for a couple who obtained a marriage license in Montgomery.

2. Sarah's road ahead: Sarah Murnaghan, the 11-year-old suffering from cystic fibrosis whose fight for new lungs sparked a national debate about organ-donor rules, has returned home after two lung transplants and a six-month stay at the Children's Hospital of Philadelphia. But the Delaware County girl still has challenges ahead, including physical therapy, check-ups and breathing without the aid of a machine.

3. School district contract talks: The Philadelphia School District and its teachers' union remain in contract talks as the first day of school approaches. The district says $103 million in concessions from the union are needed as part of a financial-rescue plan that includes state funds. The parties are meeting daily in an attempt to come to an agreement before classes begin Sept. 9.

4. No 90-degree days?: This month could be Philadelphia's first August without a 90-degree day since 1984 if the mercury fails to hit the 90s this week. Forecasters say temperatures in the mid- to high-80s are expected for the remainder of the month. Philly has failed to reach 90 at least once in August just five times in the past century.

5. More Pa. education secretary troubles: Carolyn Dumaresq was named the state's acting education secretary this week after her predecessor, William Harner, abruptly stepped down, and is already under fire. News outlets began reporting Tuesday that Dumaresq didn't report some outside income on financial disclosure forms, an oversight officials are calling an honest mistake. Harner was asked to resign after background checks reportedly discovered past allegations of inappropriate conduct.
