There will be some localized fog in parts of the region this morning as light winds and mostly clear skies are helping the development of fog around the region. Temperatures are in the 60's for the most part in the Delaware Valley, with the city flirting with 70 degrees this morning. Once any fog burns off after 7:30 this morning, mainly sunny skies will dominate the region for the duration of the day.
Expect highs this afternoon in the middle and upper 80's -- we're pegging 87 for Philadelphia although a few spots might nudge higher by a degree or two before day's end. Humidity levels will be modest so while it will be warm it won't feel too terribly hot.
