| Area Forecast Discussion National Weather Service Jacksonville FL 1245am EST Sat Nov 15 2025 Near Term (Today and Tonight)... The main weather concern today will be the fog formation over the next few hours as a surface ridge slides overhead. Before midnight, shallow radiation fog had already begun to materialize. While widespread dense fog isn't anticipated broad areas of dense fog and limited visibility will be possible across NE FL and portions of SE GA this morning. Given the dry conditions, there has been an increase in small brush fires in the area. Near these fires, enhanced fog potential and possible a very dense "superfog" formation is possible this morning. This may require targeted Dense Fog Advisories if development occurs in the vicinity of any reported brush fires. Calm and very light near-surface winds will allow fog to stay intact longer this morning. All fog should lift by 9 AM. After the fog lifts, sunny skies will warm temps into the upper 70s this afternoon. Little change in the regional pattern, though there will be an increasing southwesterly flow late tonight which may act to advect Gulf moisture into the Suwannee Valley and spread east toward Jacksonville overnight. This may lead to an advective fog event, with a chance of locally dense fog again early Sunday morning as temperatures fall to the low to mid 50s. .SHORT TERM...(Sunday and Monday) Sunday will be another warm day with breezy westerly winds ahead of an incoming weak, dry cold front from the north, with highs in the upper 70s. The front will stall over the area for most of Sunday night, with low temperatures ranging from the upper 40s north of Waycross and near 60 on the northeast Florida coast. Patchy fog will be possible mainly over north central Florida early Monday morning, but the frontal position will play into that as well. Monday will be a few degrees cooler than the rest of the week area-wide with calmer winds after the front passes through. Long Term (Tuesday through Friday) High pressure will build overhead Tuesday and Wednesday following the frontal passage early in the week leaving calm winds, clear skies, and above normal temperatures. Southeast winds will increase Thursday and Friday, bringing in some more moisture and clouds. High temperatures each day will be in the mid 70s to low 80s, generally cooler near the Atlantic coast. With no precipitation in the forecast at this time, expect drought conditions to persist, if not worsen. However, looking ahead just past this period, a stronger front may bring some showers Friday night into next weekend, but there remains a lot of uncertainty for day 8. Marine High pressure pattern will hold through today with offshore winds increasing between the high and an approaching cold front that weaken considerably as it approaches and likely stalls across the waters early next week. Light winds and fair maritime conditions continue through Thursday under the influence of high pressure. Onshore flow with a backdoor cold front will commence Thursday with a coastal trough developing Friday as winds begin to shift southerly ahead of an approaching cold front. RIP CURRENTS: Low surf and light winds will lead to a low rip current risk through the weekend. Fire Weather Dry conditions continue today, especially for inland southeast Georgia where minRH will fall to 25-30%. Moisture will improve RH Sunday briefly as a front approaches, but higher transport winds will result in areas of high dispersion on Sunday for inland locations. Critically low minRH values return north of I-10 on Monday for inland locations with calmer winds than Sunday keeping dispersion good. Moisture will gradually improve through the week keeping minRH above concerning values, although no precipitation is in the forecast this week, likely further worsening drought conditions.
