| Area Forecast Discussion National Weather Service Mount Holly NJ 128am EDT Thu September 12 2024 Synopsis High pressure over our region will dominate our weather through early next week. By then, a tropical disturbance will be located off the Southeastern United States coastline which may bring some rain back to the region by the middle of next week. Near Term - Through Tonight High pressure is centered just east of Cape Cod and will more or less remain in place through tonight. The pressure pattern is resulting in a light southeasterly flow, which is enhancing moisture transport off the ocean. Not a lot, but enough when coupled with near ideal radiational cooling to result in greater coverage of patchy fog and low clouds early this morning. Guidance has hit parts of the area pretty heavy with the fog, but will hold off on any dense fog advisories until the evolution becomes a bit more clear. That said, there's definitely a potential of dense fog advisories this morning, especially across New Jersey. Low clouds and fog look to break by mid morning and the rest of the day should turn out very similar to yesterday, including in the temp department. Meanwhile, as implied by the static pattern, tonight looks like it may be very similar to this past night is turning out, with clear conditions early giving way to patchy fog and low clouds late with similar temps. Short Term - Friday Through Saturday High pressure will be situated to our north and northeast near or off the coast of New England through much of the short term period leading to continuing onshore flow. Aloft, a Rex Block pattern will be setting up as upper level ridging builds over the Great Lakes and a closed low associated with what is currently Hurricane Francine meanders over the south-central US. All in all, this will result in dry weather with mainly clear to partly cloudy skies throughout the period with some occasional high clouds from Francine fanning in from south to north at times. There may also be a period of some low stratus that develops by early Friday over southern parts of the forecast area (Delmarva, south Jersey, SE PA). Highs will generally be in the upper 70s to mid 80s, with lows ranging from the mid 50s to low 60s. Humidity should remain rather comfortable. Long Term - Saturday Night Through Wednesday As a whole, the long term period remains relatively unchanged through the weekend as the Rex Block pattern continues. This will yield continuing dry conditions along with above normal temperatures through Sunday. The blocking pattern does appear that it will break down early next week, which may finally result in some much needed precipitation returning to the area by midweek. For now, both the GFS/ECMWF (European Centre for Medium-Range Weather Forecasts) global guidance indicate that there is potential for the development of a tropical disturbance off the Southeast US eventually lifting northward by midweek. Will have to monitor this closely as weather features following blocking patterns are often difficult to predict, but considering model to model run consistency, have maintained a 20- 30% chance of showers on Tuesday and Wednesday for much of the area. Marine No marine headlines expected through tonight. Winds generally out of the east around 5-10 kt with 2 foot seas, building to near 3 feet late tonight. Outlook... No marine headlines are expected Friday through Saturday night. However by late Sunday into early next week seas look to increase to levels near or above Small Craft Advisory levels due developing system south of our waters. Rip currents... Through Friday...Northeast winds around 10 mph will become east to locally southeast each afternoon and evening. Breaking waves in the surf zone are forecast to be around 2 feet with a period of around 8 seconds. As a result, there is a LOW risk for the development of dangerous rip currents for both the Jersey Shore and the Delaware Beaches.
