| Area Forecast Discussion National Weather Service Mount Holly NJ 841am EDT Thu April 23 2026 .WHAT HAS CHANGED... A Special Weather Statement has been issued for our eastern PA zones for fire weather concerns through the day today. .KEY MESSAGES... 1. Warm temperatures, low humidity and an afternoon breeze may result in elevated fire weather concerns in Pennsylvania today. 2. A wave of low pressure will bring widespread rainfall to the region this weekend with seasonably cool temperatures. KEY MESSAGE 1...Warm temperatures, low humidity and an afternoon breeze may result in elevated fire weather concerns in Pennsylvania today. High pressure builds both over Hudson Bay in Canada and over the Mid-Atlantic and Southeast today. Winds turn to the west- northwest and will increase to 10 to 15 mph with gusts up to 25 mph in the afternoon. Skies will be sunny and it will be quite warm with highs in the mid to upper 70s, though some spots along the I-95 corridor and interior portions of Delmarva may top off around 80. Surface dew points will mix down to the low 40s and even upper 30s with efficient mixing this afternoon. This results in MinRH values from 25 to 35 percent away from the coasts. Given this, we have coordinated with our fire weather partners and issued a Special Weather Statement for eastern PA zones for fire weather concerns. KEY MESSAGE 2...A wave of low pressure will bring widespread rainfall to the region this weekend with seasonably cool temperatures. A back door cold front sinks south of the area on Friday as high pressure settles to the north in Canada. A few showers may develop in the afternoon as some mid-level energy embedded in the northwest flow aloft clips the region, but overall conditions look to be mainly dry and cool. Forecast highs on Friday will mainly be in the 60s to around 70, perhaps pushing into the mid 70s near the Eastern Shore of MD. It should be noted that forecast guidance notoriously struggles with back door fronts and it is entirely possible that the front sinks through much faster than currently progged. This would result in much cooler temperatures than what is currently in the forecast. A low pressure system organizing near the Great Lakes region Friday night will move through the region this weekend. The latest trend has been for the bulk of the rain showers to be Saturday with Sunday trending drier. However, some model guidance does still have some showers lingering on Sunday, so I have kept slight chance to chance PoPs for Sunday. Current rainfall amounts look to total around 0.50- 1.0 inch to the north of Philadelphia and around 0.25-0.50 inches to the south of Philadelphia. Saturday will be dreary, damp, and cool with highs only in the upper 40s to upper 50s. Some improvement should be expected for Sunday, but it is fully dependent on how quickly our low pressure system exits. For Sunday, temperatures increase into the mid 50s to mid 60s. By early next week, we trend warmer than the weekend. Monday is looking dry with our next system approaching Monday night and bringing rain showers to the area into midweek. Marine Sub-Small Craft Advisory conditions through tonight. NE winds 5 to 10 kt early become then NW 10 to 15 kt later this morning, then become S in the afternoon behind afternoon sea breezes. Seas overall 2 to 4 feet. Winds shift back to N 5-10 kts tonight. VSBY restrictions possible in fog, mostly near the coasts, early this morning. Outlook...

Saturday through Sunday night...SCA (Small Craft Advisory) conditions likely to develop by Saturday evening. Winds around 15-20 kt with gusts up to 25 kt possible. Seas of 4-7 feet. Rain showers likely. Monday through Monday night...No marine headlines expected. Winds generally 10-15 kt and seas 2-4 feet. Tuesday...No marine headlines expected.
