| Area Forecast Discussion National Weather Service Mount Holly NJ 227pm EDT Fri Jun 26 2026 .WHAT HAS CHANGED... Updated all sections. .KEY MESSAGES... 1. Unsettled conditions tonight and thru Saturday as a front and weak upper systems move through. 2. Heat builds back into the region for the middle and end of next week. There is increasing confidence that high temperatures will be well in the 90s to around 100 degrees, with maximum heat index values exceeding 100 degrees. KEY MESSAGE 1... Unsettled conditions tonight and thru Saturday as a front and weak upper systems move through. A weak cold front will continue across the region tonight and the front will meander back through Saturday. The front will interact with an upper short wave tonight and another Saturday. These factors will lead to the development of showers and a few thunderstorms through the period. Higher POPS will be across Delmarva and south NJ both tonight and Saturday. While severe weather is not expected, a few thunderstorms with gusty winds may occur. It'll remain mild and humid tonight with lows in the low/mid 60s N/W and upper 60s/low 70s S/E. Highs on Saturday will generally be in the 70s with some low 80s for Delmarva and south NJ. The cold front slowly sags south into the Mid-Atlantic Saturday night. High pressure begins to build in from the north and west, but with that front nearby, and shortwave energy on the base of a mid- level trough diving into the Mid-Atlantic, showers with isolated thunderstorms will linger over the area Saturday night, with the bulk of the activity over Delmarva and extreme southern New Jersey. While most of the area dries out on Sunday, some lingering showers, and even a few thunderstorms, may continue to impact Delmarva into Sunday afternoon. KEY MESSAGE 2...Heat builds back into the region for the middle and end of next week. There is increasing confidence that high temperatures will be well in the 90s to around 100 degrees, with maximum heat index values exceeding 100 degrees. Strong mid-level ridging will develop over the Great Lakes and Ohio Valley early in the new week, then will build into the Northeast and Mid-Atlantic starting on Wednesday and continuing through the end of next week. Hot and humid conditions will return with high temperatures well into the 90s to around 100 degrees with and max heat index values over 100 degrees. 13Z/26 NBM probabilities indicate a 70 to 90 percent probability of high temperatures exceeding 95 degrees on both Thursday and Friday, with a 30 to 50 percent probability of high temperatures exceeding 100 degrees from the Lehigh Valley north on Thursday and a 60 to 80 percent probability of high temperatures exceeding 100 degrees across the Delaware Valley, including Philadelphia, southern New Jersey, and Delmarva on Thursday. Max heat index values could exceed 105 degrees, which would necessitate potential Extreme Heat Warnings. Marine A weak cold front will cross the waters early tonight and then return as a warm front Saturday. Overall, winds and seas will remain sub-SCA (Small Craft Advisory) tonight and Saturday. A few showers or a TSTM are possible this evening and into the early overnight Another period of possible showers/thunderstorms will be around Saturday with chances in the high chance/low likely category. Outlook... Saturday night through Sunday...Sub-SCA (Small Craft Advisory) conditions. VSBY restrictions in showers, scattered thunderstorms, and fog Saturday night through Sunday morning. Monday through Wednesday...Overall, sub-SCA (Small Craft Advisory) conditions. Cannot rule out a brief period of southerly 25+ kt gusts late Tuesday afternoon north of Barnegat Light. Rip Currents... For today, south-southwest winds around 10 mph with breaking waves in the surf zone of mainly 1-2 feet, with up to 2 to 3 feet with an 8 second period near the Atlantic City and Ocean City shores. This will continue the LOW risk for the development of dangerous rip currents for the Jersey Shore and Delaware Beaches. For Saturday, breaking waves in the surf zone are forecast to be around 2 feet with around a 6 second period and southeast swell. Winds should be more easterly around 10 mph across the northern Jersey Shore beaches while more southerly farther south. Despite a more onshore component to the wind at some beaches, continued the LOW risk for the development of dangerous rip currents for both the Jersey Shore and Delaware Beaches.
