Philadelphia started Saturday looking like a postcard, with dry sunshine, temperatures around 75°F, and dew points in the mid-50s that felt a lot less sticky than earlier this week. Skies stay mostly sunny and highs should push near 89°F this afternoon on a light northwest breeze. The comfy vibe will not last long, though, as higher than normal tides tonight and a round of Sunday showers and thunderstorms look ready to mess with weekend plans.
Coastal Flood Advisory Tonight
A Coastal Flood Advisory is in place this evening for parts of the Atlantic coast and Delaware Bay, lining up with the evening high tides and a new moon that will juice the tidal range. Forecasters expect widespread minor tidal flooding on exposed shorelines and low-lying riverfront streets between about 6 p.m. and midnight, so drivers and residents in vulnerable waterfront areas should be ready for some spotty street flooding, according to the National Weather Service.
Storms Return Sunday, With Severe Potential
Showers and thunderstorms make a comeback Sunday, June 14, mainly from late afternoon into the evening, roughly 4 to 11 p.m., with the odds ticking up after about 3 p.m. A few storms could turn severe, with damaging winds the main concern and an isolated tornado possible from southeast Pennsylvania into southern New Jersey and the Delmarva.
Heavy downpours late Sunday into Sunday night may trigger brief urban flooding where storms move through quickly, and gusts up to about 25 mph are possible in stronger cells. If you are planning outdoor events Sunday evening, build in a fallback plan, since anything outside could need a pause or an early wrap if those stronger storms fire.
Beaches, Boats And The Commute
Boaters should keep a close eye on forecasts, since a brief Small Craft Advisory may be needed Sunday afternoon and evening as storms roll through. Beachgoers in Cape May and Atlantic counties should also be aware of an elevated rip current risk, even if the sky looks inviting for a swim.
On the roads, the rule still holds: do not try to drive through standing water. Even shallow flooding can stall a car, hide road damage, and turn a quick errand into a call to a tow truck.
What To Expect Next Week
Once the front pushes through, cooler and less humid air settles in for the start of the workweek. Monday should top out near 79°F with plenty of sun. By midweek, temperatures rebound into the low 80s and scattered afternoon storms look to return by Wednesday. Thursday is currently projected to be the warmest day, with highs near 91°F.
