A cold front arrives later Sunday afternoon and evening. Some thunderstorms are expected, and there is the potential for isolated severe thunderstorms. This front will break the heat and humidity as we go into next week. #pawx #njwx #mdwx #dewx

Today we have a marginal risk for severe weather. As the week goes on, we're focusing on the impacts from Hurricane Erin via Rip Currents, Beach Erosion, High Surf, and Coastal Flooding. See our Weather Story (weather.gov/phi/weathersto…) for the latest information.

A few storms (one or two severe) will continue into the evening hours before diminishing/moving offshore. A cold front will pass through the region overnight, bringing northeasterly winds and widespread clouds. Monday will be much cooler than recent days. #NJwx #PAwx #DEwx #MDwx

Its going to be a bit cooler than normal this week but our eyes will be turned towards the DE Beaches and the Shore this week. Even though Hurricane Erin is forecast to stay well offshore Coastal Flooding, High Surf, Dangerous Rip Currents, and beach erosion are all expected.

4.84" of rain fell at our office yesterday, which is the 5th highest 1-day total ever recorded at WFO Mount Holly/Philadelphia since the office opened in 1993. One of our forecasters measured 5.50" at their home from yesterday's storms. #NJwx

The 4 1-day totals ahead of yesterday are: 1. 6.25" - July 23, 2013 2. 5.83" - August 28, 2011 (Irene) 3. 4.98" - June 11, 2018 4. 4.87" - April 16, 2007

Dangerous conditions along the Jersey Shore and Delaware Beaches this week as ocean conditions worsen. This is due to prolonged onshore winds, building seas and also increasing swell energy from distant Hurricane Erin. Stay safe as the ocean water is very powerful. #njwx #dewx

Much cooler this week with a few showers around. Hazards are for the coastal and marine areas due to dangerous rip currents and surf. #dewx #njwx #mdwx #pawx
