PHILADELPHIA (CBS) — Tuesday was another stellar day across the Delaware Valley, with sunny skies and highs right where they should be in the upper 60s and low 70s.

Some changes will start to occur during the day on Wednesday. Clouds will return from the southwest in response to a warmer air mass that will move into the region late week. Highs on Wednesday will be similar to today in the upper 60s to near 70.

A warm front moving northward will bring a chance of showers Wednesday night and on Thursday, with highs on Thursday near 70.

After the warm front passes on Friday, the warm air mass behind the front pushed into the Delaware Valley. If enough sun breaks out of Friday, high temperatures would reach 80 degrees.

It looks like the warm air will stay in place for Mother’s Day weekend. However, a weak cold front will bring a chance of a few scattered showers or a thunderstorm on Saturday with highs again near 80. There will still be a slight chance for a shower on Mother’s Day with highs once again well above average in the upper 70s to near 80.

In case you’ve ever wondered if it can snow in May, a trace of snow fell in Philadelphia on this day in 1891. The latest date in May it has ever snowed in the city is May 8th, but don’t worry, there is no snow in the forecast!
