The Philadelphia region looks to be in store for a washed-out Saturday, with potentially record-setting rain soaking the area.

The National Weather Service says to expect rain to start overnight Friday into Saturday and continuing throughout the day.

Showers could be heavy at times, with places across the area seeing one to three inches of rain in total.

Heavy rain is most likely from morning through early afternoon, forecasters said, though models were differing in how much rain to expect. Philadelphia appeared likely to see between one and two inches of rain, a bit less than initially predicted in earlier forecasts.

That amount could threaten Philadelphia's longtime rainfall record for the date. The record rainfall for May 13 now stands at 1.4 inches, set in 1948.

Flooding in urban and poor-drainage areas is the primary concern, the weather service said, though widespread flooding is not expected.

For today, the weather service said to expect cooler-than-normal temperatures, with a high in the low 60s. There's also a slight chance of showers, forecasters said.

After a cool and wet Saturday (a high around 60 degrees is expected), somewhat warmer and drier conditions are likely for Mother's Day. There's a chance of lingering showers through Sunday morning, but partly sunny skies and temperatures in the high 60s are expected later in the day. Sunday is also expected to be breezy.
