973 FXUS61 KPHI 230716 AFDPHI Area Forecast Discussion National Weather Service Mount Holly NJ 316 AM EDT Sun Aug 23 2026 .WHAT HAS CHANGED... Updated Aviation section for the 06Z TAFs. && .KEY MESSAGES... 1. A cold front passes through the region later this morning. Conditions improve this afternoon. 2. Fair weather is expected to return later Sunday and should persist into the middle of the upcoming week. && .DISCUSSION... KEY MESSAGE 1...A cold front passes through the region later this morning. Conditions improve this afternoon. Low pressure tracking across central Canada will first pull a warm front through the region early this morning, and then a cold front passes through the region later this morning. Ahead of this front, showers and scattered thunderstorms are moving through southeast Pennsylvania and into New Jersey, while some additional showers are moving through Delmarva and southern New Jersey. While there is a good deal of CIN over the area, the first wave of showers and scattered thunderstorms are moving into an area with MUCAPE upwards of 1500 J/kg. So these storms may bubble up a bit, especially with some 40 kt of 0-6 km Bulk Shear. While organized severe weather is unlikely, cannot rule out an isolated severe thunderstorm or 2 going into daybreak. Cold front then passes through the region late this morning. A drier airmass spreads into the region with surface dewpoints dropping from the upper 60s to around 70 to the low 60. Skies clear out this afternoon as high pressure builds in from the west. KEY MESSAGE 2...Fair weather is expected to return later Sunday and should persist into the middle of the upcoming week. More zonal flow with some subtle ridging moves in for the first half of the week. At the surface, high pressure will mainly be in control, resulting in dry and tranquil weather through Wednesday. Temperatures should be seasonable through this stretch. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/...
