| Area Forecast Discussion National Weather Service Jacksonville FL 255pm EST Fri Feb 6 2026 .KEY MESSAGES... For the latest NE FL and SE GA Daily Key Messages please visit: https:/www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf - Red Flag Warning through 6pm today. Areas impacted: portions of northeast and north central FL, generally for locations east of I-75 and portions of Ware & Charlton Counties. - Strong westerly winds continue through sunset, with frequent gusts of 25-35 mph. Minimum relative humidity around 25% extends to coastal Northeast FL. Elevated Fire Danger elsewhere across our region this afternoon. - Marine Hazards Small Craft Advisory for the near shore waters through Saturday. Gale Warning for the offshore coastal waters this evening through early morning hours on Saturday. - Freeze Watch posted for Saturday night and early Sunday morning for inland locations along and west of I-95. Widespread frost possible. Near Term - Through Tonight Afternoon surface analysis depicts a reinforcing cold front pushing southeastward through the Ozarks, Tennessee, and Ohio Valleys. Aloft...a potent shortwave trough diving quickly southeastward across the southern Appalachians was reinforcing a deep trough that was in place across the eastern half of the nation. Latest GOES-East derived Total Precipitable Water imagery indicates that a dry air mass prevails across the southeastern states, with PWATs (Precipitable Waters) generally around or just below one-half inch throughout our area. Our local pressure gradient continues to tighten ahead of the approaching cold front, with west winds sustained at 15-20 mph for most of our area, with gusts of 25-35 mph becoming more frequent as the afternoon progresses. Full sunshine, a dry air mass, and some weak warm air advection ahead of the approaching front has boosted temperatures to the 60-65 degree range as of 19Z, with dewpoints ranging from the upper 20s to the mid 30s. The reinforcing shortwave trough moving across the Appalachians this afternoon reaching the Carolina coast this evening. This feature is pushing a dry cold front into the southeastern states this afternoon, with this feature crossing our area during the predawn and early morning hours on Saturday. A tightening local pressure gradient downstream of this approaching front will maintain frequent westerly wind gusts of 25-35 mph across our area through sunset this evening. Given the ongoing drought conditions and humidity values plunging to near critical thresholds this afternoon, a relatively rare Red Flag Warning continues through 6pm for most locations east of the I-75 corridor in northeast and north central FL, including a small portion of inland southeast GA. Strong offshore winds are allowing critically low humidity values to extend to coastal locations in northeast FL this afternoon, with breezy conditions expected to persist into the early evening hours tonight. An Elevated Fire Danger is expected elsewhere, even though minimum humidity values should stay just above critical thresholds as the afternoon progresses. Winds will shift to northwesterly in the wake of the frontal passage by the predawn hours on Saturday, with late arriving cold air advection dropping lows into the upper 30s for inland locations north of the I-10 corridor, with low to mid 40s prevailing elsewhere. Wind chill values may fall below freezing towards sunrise across inland portions of southeast GA. Short Term - Saturday Through Sunday Night High pressure begins to build over the region after the passage of a dry cold front during the early predawn hours on Saturday. Cool daytime temperatures are anticipated to continue through the weekend, with another night of near to subfreezing temperatures for much of the local area during the overnight hours into Sunday morning. A light northwesterly breeze, with gusts from 15 mph to 17 mph, develops on Saturday behind the frontal passage. Daytime highs on Saturday will be in the upper 50s to mid 60s, with temperatures warming on Sunday bringing highs into the 60s area- wide as clear skies continue through the upcoming weekend. Saturday night will bring another round of near to sub-freezing temperatures as clear skies will enhance Radiational Cooling during the overnight hours. Inland SE GA, the Suwannee River Valley, and inland locations of NE FL west of Jacksonville towards the I-75 corridor, are currently under a Freeze Watch as temperatures will begin to drop during the overnight hours into early Sunday morning. Widespread Frost will also be likely as winds become near calm. "Warmer" temperatures on Sunday night as cloud cover begins increase during the overnight hours, helping to keep Lows primarily above Freezing, but still in the mid to upper 30s for inland locations and the lower 40s along the coast. Long Term - Monday Through Friday A warmer pattern arrives next week, with High pressure overhead through midweek. The next chance of showers will be after midweek, as high pressure begins to shift away to the Atlantic ahead of a frontal boundary moving towards the area. Temperatures will be near and above the seasonal average through the week. Marine Breezy west-southwesterly winds will continue this evening ahead of an approaching dry cold front. Small Craft Advisory conditions will prevail through around sunset for the offshore waters, followed by increasing wind speeds and gusts from this evening through the early morning hours on Saturday, prompting a Gale Warning for the offshore waters. Wind speeds near shore will increase to Small Craft Advisory levels later this afternoon, with occasional Gale Force wind gusts expected tonight. Arctic high pressure building over the Upper Midwest in the wake of this cold front will shift southeastward over the Ohio Valley by late Saturday afternoon. Strong northwesterly winds during the morning hours will shift to northerly while gradually decreasing on Saturday afternoon and evening, with speeds falling below Small Craft Advisory levels for the offshore waters adjacent to northeast Florida by sunset. Winds will briefly shift to northeasterly on Sunday as high pressure begins to build over the Florida peninsula, allowing for winds and seas to diminish. Light westerly winds will then prevail early next week as high pressure remains centered to the south of our local waters. Rip Currents Low to Moderate Risk in the strong offshore flow with surf/breakers only in the 1-3 ft range through Saturday. Fire Weather - High daytime dispersions on Saturday - Critically low humidity values through this evening for portions of northeast and north central FL and a small portion of inland southeast GA. - Minimum humidity values in the 20s and 30s this weekend Gusty westerly winds, gusts from 25 mph to 30 mph possible, combined with severe to extreme Drought conditions and critical RH values prompted the issuance of a Red Flag Warning across portions of northeast Florida east of I-75 towards the Atlantic coast and for portions of Ware and Charlton County in southeast Georgia from 12pm to 6pm this afternoon to early evening. Elevated Fire Weather conditions also expected for areas not in the current Red Flag Warning. Additionally, elevated dispersions will develop as winds and gusts begin to increase during the afternoon to early evening hours Today. High pressure conditions will build through the weekend with humidity levels gradually rising into the coming week as the prevailing flow shifts to become more out of the gulf. FOG POTENTIAL AND OTHER REMARKS: Inland frost and freeze expected Saturday night. Significant fog developments are not expected.
