| Area Forecast Discussion National Weather Service Mount Holly NJ 313pm EDT Thu Oct 1 2026 .WHAT HAS CHANGED... Updated aviation, marine, key message 1. .KEY MESSAGES... 1. Above normal temperatures and increasing chances of showers for the end of the week. 2. Unsettled conditions are expected for the later part of the weekend. Chances for rain on Sunday have increased. 3. Tidal flooding continues to recede in the back bays of New Jersey and Delaware. KEY MESSAGE 1... Above normal temperatures and increasing chances of showers for the end of the week. High pressure offshore will continue to pump milder and increasingly more humid air across the area through Friday. High temps will be much above normal on Friday. Dry conditions should prevail through midday Friday. This will change Friday afternoon as a cold front will pass across the region late Friday and Friday night and will settle over Delmarva on Saturday. Scattered showers will develop Friday afternoon, mainly north and west of the I-95 corridor, then scattered showers spread east Friday night. The showers taper off in most areas by Saturday morning, but across southern Delaware and south NJ, we'll keep some clouds and scattered showers for Saturday as the front becomes nearly stationary over the Mid- Atlantic. Overall, Quantitative Precipitation Forecast will be less than 1/10 inch but a few areas closer to 2/10ths of an inch possible. KEY MESSAGE 2...Unsettled conditions are expected for the later part of the weekend. Chances for rain on Sunday have increased. Cooler and drier into early next week. High pressure then builds into the region from the north on Saturday. Mostly sunny skies for most of the area and partly to mostly cloudy skies across Delmarva and extreme southern New Jersey with seasonable, but slightly below normal temperatures with highs in the upper 60s to around 70 degrees. After that, low pressure develops on that stalled front and passes cross the Mid-Atlantic and Delmarva Sunday and Sunday night. The overnight models continue the previous trend of bringing higher POPs further north for Sunday. The present forecast now has low-end likely POPS for southern Delaware and the 50% chance line runs along the Delaware valley and up into Monmouth County. Low chance probability of precipitation are included now for the southern Poconos and Lehigh Valley High pressure and a much cooler air mass then builds into the region starting Monday into Tuesday. High temperatures Tuesday are only near 60 degrees for much of the region, which is upwards of 10 degrees below normal. Some patchy frost is possible by Tuesday night into Wednesday morning. Forecast lows are in the mid 30s north of I-78, and in the low to mid 40s elsewhere. KEY MESSAGE 3...Tidal flooding continues to recede in the back bays of New Jersey and Delaware. Tidal levels continue to decline and recede as offshore flow continues to allow the back bays to drain. Some of the back bays of Barnegat Bay, Rehoboth Bay, Jefferson Creek and Little Assawoman Bay may see some spotty minor tidal flooding continue today, as winds turn more shore parallel and slow the rate of drainage. However, the bulk of the threat is over. As a result, no coastal flooding headlines are currently in effect. No further tidal flooding is expected elsewhere. Marine Through Friday...sub-SCA, though with southwest winds increasing to 10-15 kts and seas building to 3-4 ft. Spotty showers possible late Friday. Friday night... More sub-SCA (Small Craft Advisory) with scattered showers Friday evening. Ocean Seas 3-4 ft. Outlook... Generally sub-SCA (Small Craft Advisory) thru the weekend and into next week. Two periods where conditions may approach SCA (Small Craft Advisory) are Saturday morning when some gusts 20 to 25 kts are expected.Also, Monday night may see increasing seas 4-5 ft as NW winds develop across the waters.
