000 FXUS61 KPHI 281304 AFDPHI Area Forecast Discussion National Weather Service Mount Holly NJ 904 AM EDT Wed Oct 28 2026 .WHAT HAS CHANGED... Added a brief discussion about spotty minor tidal flooding through tomorrow morning. && .KEY MESSAGES... 1. Spotty minor tidal flooding expected with the morning high tide through Thursday morning. 2. No other significant weather concerns this week. && .DISCUSSION... KEY MESSAGE 1...Spotty minor tidal flooding expected with the morning high tide through Thursday Morning. Elevated astro tides from the recent full moon and weak onshore flow earlier in the week has resulted in some spotty minor tidal flooding across portions of the southern NJ and Delaware coastline and areas within Delaware Bay. Some areas could get close to widespread minor tidal flooding, such as Bowers Beach, DE and areas in Cape May County later this morning but elected to hold off on any advisories for now. For those same areas, some spotty minor tidal flooding is possible tomorrow morning, but tide levels should be lower than this morning. No tidal flooding expected on the tidal Delaware River, northern NJ coast, or Chesapeake Bay. KEY MESSAGE 2...No other significant weather concerns this week. High pressure centered over New England will build east and then move offshore tonight. A weak cold front passes through the region Friday, and then high pressure returns for the weekend. Low pressure may approach the region for the start of next week. With high pressure remaining north/northeast of the area today, we expect another sunny and dry day. High temps will range from the upper 50s/low 60s across the far N/W areas to the mid/upper 60s elsewhere. These temps a bit above normal for Oct. 28. After that, dry conditions through Saturday with high temperatures generally from the mid and upper 60s on Wednesday to the mid 70s or so by Friday. Cooler, but still slightly above normal temperatures expected for this weekend. Rain may arrive on Sunday or Monday depending on the timing, strength, and placement of that aforementioned low pressure system. && .AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
