Mostly sunny skies and comfortable humidity in Philadelphia today

PHILADELPHIA (CBS) -- It's been nine weeks since our last rain-free weekend, and this one was close to perfect with sunshine, seasonal temperatures and low humidity continuing through Sunday.

The 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.

Next, we focus on an area of Low-pressure that will park off the Jersey shore bringing clouds tonight and shower chances on Monday. The unsettled weather will continue with scattered showers and storms Tuesday and Wednesday as another system arrives from the Midwest.

Temperatures will hover near or below average Monday through Wednesday but edge upwards to the 90's 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 week ahead.

Light smoke in the upper atmosphere will also drift past the Lehigh Valley, Berks and the Poconos through Monday providing the chance for a pretty sunset tonight but no air quality issues. Rain chances the next several days will keep our area clear of any smoke.

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
