We won't call it a washout, but there's a chance of showers or thunderstorms through the Labor Day holiday weekend in the Philadelphia area.
The latest National Weather Service forecast has lowered the chances of rain for Saturday, Sunday, and Monday and shifted most of the shower and thunderstorm action to Friday, meaning those headed to the Made in America festival might stay fairly dry.
A "hazardous weather outlook" issued for the entire region Friday morning says: "Some showers and thunderstorms today will be capable of very heavy downpours leading to localized flooding especially in poor drainage areas."
Serious thunderstorms erupted in Delaware Friday afternoon and the weather service said its radar at Dover Air Force Base may have been knocked out of service by a lightning strike.
The chances of precipitation — in the form of showers or thunderstorms — for the weekend are now mostly in the 30 percent range Saturday through Monday, with a 40 percent chance of thunderstorms Sunday afternoon.
That means there is that percentage of a chance of precipitation somewhere in the Philadelphia region, but not necessarily in your backyard or on the Benjamin Franklin Parkway, where the Made in America festival will be held Saturday and Sunday.
After four days of 90-plus highs, a weakening cold front also is bringing lower temperatures to the region.
The current forecast calls for highs of 79 degrees Friday, 81 Saturday, 86 Sunday, and 88 Monday in Philadelphia. Overnight lows should be in the low 70s. Temperatures should be slightly cooler at the Shore.
The one bright spot in what looks like a weekend of clouds is Labor Day, when the forecast calls for partly sunny skies in Philadelphia and mostly sunny skies at the Shore.
