For the latest NE FL and SE GA Daily Key Messages please visit: https://www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf - Areas of Dense Fog Late Tonight and Early Friday Morning - Near Record High Temperatures and Isolated Thunderstorms Possible over the Weekend - Small Craft Advisories Likely Sunday Night through Tuesday. Gale Warnings Possible Monday Afternoon through Monday Night - Frost & Light Freeze Potential Inland on Tuesday and Wednesday Mornings - Elevated Fire Danger Monday and Tuesday && .SYNOPSIS... Issued at 207 AM EST Fri Nov 7 2025 Overnight surface analysis depicts a stalled frontal boundary situated from the Savannah River Entrance northwestward across central GA and extending into the Tennessee Valley. Meanwhile, high pressure (1023 millibars) situated to the north of this boundary was sliding eastward and offshore of the Delmarva peninsula. Otherwise, another frontal system was pushing southeastward across the Upper Midwest and the Plains states. Aloft...zonal flow prevails across the southeastern states, downstream of a northern stream trough that was beginning to dig southeastward from the Upper Midwest. A weak, moisture-starved shortwave embedded within the zonal flow was traversing the northern Gulf coast, spreading a swath of mostly high altitude cloud cover that was poised to move offshore of coastal southeast GA overnight, with this cloud cover also exiting the Suwannee Valley and extending across the rest of northeast and north central FL. Locally dense fog is already beginning to develop across portions of inland southeast GA in the wake of this departing cloud cover. Temperatures and dewpoints at 07Z ranged from the upper 40s and lower 50s across inland southeast GA to the low and mid 60s along the northeast FL coast. && .NEAR TERM... (through Tonight) Issued at 207 AM EST Fri Nov 7 2025 Areas of dense fog and low stratus ceilings will overspread most of southeast GA overnight, with these conditions likely expanding to the Interstate 10 and possibly I-75 corridors during the predawn and early morning hours on Friday. Dense Fog Advisories may become necessary for these locations during the early morning hours, followed by fog and low stratus clouds dissipating by the mid-morning hours. Weak shortwave energy migrating eastward across the FL panhandle and eastern Gulf this morning may sharpen a coastal trough over the northeast FL waters enough to develop a few light showers or sprinkles along the Flagler and St. Johns County coasts early this morning, with stratocumulus cloud cover expected to expand across coastal northeast FL throughout the morning hours before shifting northward along coastal southeast GA towards noon. Chances for measurable rainfall will remain confined to the Atlantic coastal waters this morning. Otherwise, zonal flow will prevail locally today, with the stalled frontal boundary across central and eastern GA lifting northward as a warm front across the Carolinas in response to a trough aloft and associated surface frontal system digging across the Ohio and Tennessee Valleys by this evening. A weak pressure pattern will remain in place locally, allowing for the Gulf and Atlantic sea breezes to develop and move inland as skies become fair later this morning. These boundaries will have little in the way of moisture to work with in our prevailing subsident air mass this afternoon, with plenty of sunshine boosting inland highs to the low and mid 80s. The afternoon sea breeze will keep coastal highs in the upper 70s to lower 80s today. Deep-layered southwesterly flow develops tonight downstream of a progressive trough that will be crossing the Appalachians from the Ohio and Tennessee Valleys. This front will drive a frontal boundary into the southeastern states overnight, with a narrow ribbon of PWATs at or above 1.5 inches surging off of the northern Gulf, across the FL Panhandle and into portions of inland southeast GA during the predawn and early morning hours. This enhanced moisture could develop a few showers towards sunrise for locations west of the Suwannee River and along the Alapaha / Ocmulgee / Upper Altamaha Rivers in interior southeast GA. Low stratus clouds and fog will likely advect off Apalachee Bay across the I-75 corridor in the Suwannee Valley during the overnight and predawn hours, with patchy to areas of locally dense fog possible elsewhere in northeast and north central FL towards sunrise on Saturday. Lows tonight will generally fall to the upper 50s and lower 60s area-wide. && .SHORT TERM... (Saturday through Sunday night) Issued at 207 AM EST Fri Nov 7 2025 Warm southwesterly flow continues on Saturday as high pressure moves further eastward into the Atlantic. A weakening front will approach north and western areas Saturday Morning before stalling prior to reaching the area later in the day on Saturday, which could spawn a few showers with a very low chance of a thunderstorm during mainly the first half of Saturday. Confidence is rather low however given the modestly dry airmass already in place. Expecting mainly an increase in cloud cover over interior GA and the upper Suwannee Valley with more sun that clouds more likely over much of northeast FL. Temps in the low to mid 80s will be common Saturday, which may flirt with record highs, especially for JAX and CRG. Potential for fog certainly looks to be in place once again late Saturday Night and into Sunday Morning given the increasing surface moisture as much milder lows in the 60s will be common area wide. As has been discussed for the past several days, a much stronger front approaches the region during the day on Sunday ahead of an impressive longwave trough digging into the southeastern states through Sunday Night. The front itself is expected to enter interior GA around late Sunday Afternoon or Sunday Evening, quickly progressing southeastward across northeast FL through early Monday Morning. Though the upper level trough and dynamics are quite impressive, they mostly lag behind the surface frontal boundary. In addition, mean layer moisture is rather unimpressive as PWATs only peak in the 1.25 to 1.5 inch range out ahead of the front. Therefore, only expecting isolated to widely scattered showers with the pre frontal trough with a slight chance of a few thunderstorms, with the highest chances of a t`storm being generally north and west of Waycross closer to the most favorable dynamics during daytime heating/highest instability. Warm conditions will continue out ahead of the front with breezy southwesterly winds, as low to mid 80s will be expected once again for high temps. Depending on how many breaks in cloud cover we get on Sunday, would certainly not be surprised if some areas over northeast FL make a push towards the upper 80s. Strong cold air advection fills in from northwest to southeast throughout Sunday Night, as breezy northwesterly winds develop and temperatures crash rather quickly along with decreasing clouds. A drop of 30+ degrees will be quite possible for many areas Sunday Night and into Monday Morning, as temps well into the 70s area wide near sunset Sunday drop into the 40s over southeast GA and the Upper Suwannee Valley, and into the low to mid 50s from about Jacksonville to Gainesville south and eastward. && .LONG TERM... (Monday through Thursday) Issued at 207 AM EST Fri Nov 7 2025 The long term starts with some of the coolest temps of the fall/winter season thus far as high pressure builds in from the north and west. Near zero rain chances and little to no cloud cover is expected for most if not all of the long term period as the associated surface high moves almost directly over the area by Wednesday and lingers near the area through Thursday. Our first significant frost and freeze of the season will be likely both Monday Night and Tuesday Night, especially as blustery northwesterly winds continue to subside as the high moves closer to the area. Temps do rebound a bit later on Wednesday and into Thursday, though still leaning below normal. && .AVIATION... (06Z TAFS) Issued at 1234 AM EST Fri Nov 7 2025 LIFR conditions will likely continue at VQQ through around 13Z. IFR to LIFR conditions are expected to develop at the rest of the terminals after 08Z as high cloud cover exits the region, except at SGJ, where stratocumulus clouds around 3,500 feet are forecast to overspread the terminal during the predawn and early morning hours, possibly accompanied by light showers or sprinkles. These VFR ceilings could spread northward towards CRG after 13Z, likely scouring out lower visibilities by that time frame. VFR conditions will then prevail at the regional terminals before 15Z. Light and variable surface winds will continue through around 16Z Friday at the regional terminals, with southerly winds sustained at 5-10 knots developing early on Friday afternoon at the inland terminals that will shift to southwesterly at GNV by 22Z. Meanwhile, the Atlantic sea breeze will develop and cross the SGJ and SSI coastal terminals around 17Z, where easterly surface winds will increase to around 10 knots. This boundary will shift inland, crossing the Duval County terminals by the mid to late afternoon hours. && .MARINE... Issued at 207 AM EST Fri Nov 7 2025 Fog may impact the waters north of Mayport early on Friday morning. Otherwise, a stalled frontal boundary just north of the Georgia waters will lift northward as a warm front on Friday, with light onshore winds prevailing across our local waters. Southwesterly winds will develop on Saturday ahead of a strong cold front that will be entering the southeastern U.S. Seas of 2 to 3 feet will prevail both near shore and offshore through Sunday evening. Isolated showers will be possible ahead of this front on Sunday afternoon and evening. This strong front will cross our local waters during the overnight hours Sunday night and the predawn hours on Monday, with westerly winds strengthening after midnight and then shifting to northwesterly by sunrise. Small Craft Advisory conditions will quickly overspread our local waters after midnight as speeds increase to 20-25 knots. Seas will build to the 3-5 foot range by early Monday near shore and then will peak in the 5-7 foot range by late Monday afternoon and evening. Meanwhile, seas offshore will build to Caution levels of 4-6 feet after midnight on Sunday night, peaking in the 6-9 foot range from Monday afternoon through Tuesday. Strong high pressure building into the southeastern states on Monday will result in occasional Gale Force wind gusts through Monday night. High pressure will shift eastward and will become centered directly over our local waters by midweek, allowing for winds and seas to gradually diminish. Rip Currents: Onshore winds developing this afternoon and again on Saturday afternoon in the wake of the inland moving Atlantic sea breeze may allow for a lower end moderate risks at the northeast FL beaches. Low surf heights will maintain a low overall risk at the southeast GA beaches through the weekend. Gradually strengthening southwesterly winds on Sunday will yield a low risk at all area beaches. && .FIRE WEATHER... Issued at 207 AM EST Fri Nov 7 2025 High pressure shifts further into the Atlantic through Saturday, with wind direction veering rather quickly towards the southwest accordingly. Both lower level winds and mixing will be sufficient enough for good dispersions inland, and even high in some areas over far inland GA. Southwesterly flow and good dispersions will continue inland for Saturday, though more cloud cover and isolated showers and perhaps a thunderstorm will be possible, mainly for areas more north and west. Flow increases on Sunday ahead of a strong cold front that will move through Sunday Night and into Monday. This will bring much cooler, breezy, and drier airmass into early next week. A freeze looks likely for many areas Tuesday and Wednesday morning. In addition, critically low daytime RH and breezy winds may lead to Red Flag conditions Monday and Tuesday next week. && .CLIMATE...
