| Area Forecast Discussion National Weather Service Jacksonville FL 637pm EST Tuesday Nov 18 2025 Near Term Issued at 1241pm EST Tuesday Nov 18 2025 A weak and subtle front/trough just offshore to the east today will lift off to the northeast tonight as the area remains under the influence of the western periphery of a surface ridge. Some scattered low level clouds are streaming towards the coast and just onshore at times thanks to the coastal trough, but otherwise a mostly sunny and mild rest of the day will be expected with highs in the upper 70s to low 80s inland. The more onshore flow will keep conditions a bit cooler near the coast as highs stay in the low to mid 70s range. Very weak flow overnight and a bit more low level moisture thanks to the onshore flow today will up our fog chances tonight, especially south and east of about the Waycross area. Patchy to areas of fog will be likely as well as patchy dense fog with visibilities under 1/2 mile at times. Low temps will range from the upper 40s to low 50s inland and the mid to upper 50s closer to the coast and St. Johns River. .SHORT TERM... (Wednesday through Thursday night) Issued at 1241pm EST Tuesday Nov 18 2025 After a foggy morning, skies will clear and pave the way for above normal temperatures as high pressure remains overhead. Highs will climb into the 80s inland and the immediate northeast Florida coast, while the southeast Georgia coast peaks in the upper 70s. Another round of morning fog will be likely Thursday morning over most of inland northeast Florida as lows drop into the 50s to low 60s near the water. Thursday will again be above average for temperatures in the 80s inland, with coastal temperatures in the mid to upper 70s as a light coastal breeze develops. Long Term (Friday through next Tuesday) Issued at 1241pm EST Tuesday Nov 18 2025 Dry and warm conditions continue on Friday with inland highs reaching the 80s again with partly cloudy skies as more moisture influxes the area from an approaching front. The front will bring isolated to scattered showers and perhaps a thunderstorm Saturday afternoon over far inland southeast Georgia. The front will pass through this weekend leaving dry conditions, but will not lower temperatures much, keeping highs above normal. Marine Issued at 1241pm EST Tuesday Nov 18 2025 A weak and coastal trough over the waters will lift northeastward tonight, with a a few isolated showers possible off the northeast Florida coast through the afternoon and evening. Otherwise, high pressure will be the dominant weather feature through the end of the week resulting in light winds and low seas across the local waters. Patchy to areas of fog will be possible within about 10 miles of the coast each morning over the next several days. Over the weekend, winds turn offshore and become breezy as a cold front approaches and passes Sunday night. High pressure building in behind the front will move offshore to the northeast early next week setting up onshore flow and development of a coastal trough. Rip Currents Rip current risk is moderate today with onshore flow. This risk falls slightly Wednesday and through the rest of the week.
