Why was it so foggy this week? Grant Gilmore explains

 

The fog has been so stubborn for the last few days - but if you're wondering how it forms and why it's so foggy, Grant Gilmore explains in the video above filmed Thursday.

Saturday afternoon, the fog gave way to a cloudy but mild and dry day. Don't plan on sunshine, but any outdoor activities will be good to go.

We're looking at a high of 49 degrees in Philadelphia, slightly lower in the Lehigh Valley and at the Jersey Shore.

Then we're looking at more rain spreading over the area Saturday evening, likely persisting through Sunday.

This rain could be heavy at times, particular overnight into the early hours of Sunday morning.

Sunday night, this rain will mostly move offshore as cooler air begins to move in to our area. That could change some of the lingering precipitation to a wintry mix, but it's looking like the cold air won't arrive in time for this to produce any significant snow for us.

After this, we're looking at a mostly clear week with highs in the 40s and lows in the 30s.

Here's your 7-day forecast:
