Mostly sunny skies and comfortable humidity in Philadelphia today

PHILADELPHIA (CBS) -- With just a few clouds overnight, the Philadelphia area capped the first half of the weekend with nice skies, low humidity and very comfortable temperatures. Sunday morning started in the 60s for most areas, with 50s in the Poconos!

Sunday afternoon ushers in a few more clouds, higher temperatures and slightly higher humidity levels. Highs Sunday afternoon will be in the mid-to-upper 80s, and near 90 in the city.

This weekend also marks the first weekend this summer that we've been rain free!

Low pressure then moves offshore Monday, bringing with it increasing clouds and a chance of showers and storms through the middle of the week. A few lingering showers and non-severe rumbles may stick around through Friday, however.

Temperatures will hover near or below average Monday through Wednesday but edge upwards to the 90s by Thursday and beyond. Signaling another possible heat wave by next weekend.

Will Philadelphia see smoke from the western wildfires?

You have probably heard about the giant wildfires across California, Oregon and Canada. Hundreds of thousands of acres have burned destroying homes, towns, and state and federal forests.

Sadly, the largest fire in California, the Park Fire in Chico, California, was caused by arson. The Park Fire is almost three times the size of Philadelphia and remains out of control.

Smoke from the Park Fire is so thick that it is visible on satellite imagery. The question is, will we see smoke from these western fires? Until now it has remained over the western U.S. and Canada, but it will drift across the northern plains, Great Lakes and upper Midwest through the weekend.

Light smoke in the upper atmosphere will also drift past the Delaware Valley through Monday but northeast winds and rain from that low-pressure which will park off the Jersey Shore next week will keep us smoke-free through Friday.

Here's your 7-day forecast:

Sunday: High of 90, mostly sunny

Monday: High of 89, low of 72, cloudy

Tuesday: High of 85, low of 75, chance for storms

Wednesday: High of 87, low of 73, chance for storms

Thursday: High of 94, low of 74, partly sunny

Friday: High of 93, low of 75, chance for storms
