166 FXUS62 KJAX 300540 AFDJAX Area Forecast Discussion National Weather Service Jacksonville FL 1240 AM EST Sun Nov 30 2025 .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 - Extreme Drought for Inland Areas. Practice Fire Safety & Check for Local Burn Bans - Strong to Isolated Severe Thunderstorm Risk Tuesday. Tuesday Morning Southeast GA & Suwannee River Valley. Tuesday Midday - Afternoon: Remainder of NE Florida. Main Stronger Storm Hazards: Gusty 50-70 mph & Isolated Tornadoes - Inland Frost Southeast GA Thursday Morning && .NEAR TERM /THROUGH TONIGHT/... Calm winds and partly to mostly cloudy skies overnight are expected, with low temperatures ranging from the lower to mid 40s over inland southeast Georgia, to near 60 degrees on the northeast Florida coast. Sunday, mainly calm and variable winds will be present as a warm front attempts to lift northward over the Florida peninsula and a cold front moves into the area from the northwest. Southwest steering flow will bring in moisture across the area, with PWATs climbing near 1 inch and with partly cloudy skies. Onshore breeze overnight will keep low temperatures near the coast and St. Johns river basin in the lower 60s, elsewhere will see lows in the 50s. A few light sprinkles will be possible over the outer Atlantic waters early this morning, but the isolated shower potential will increase Sunday night over the waters and near sunrise for inland southeast Georgia Monday. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Increasing rain chances Monday into Monday night with mainly isolated to scattered showers as a warm front lifts northward across the local area. A few stronger storms are possible over the adjacent coastal waters Monday night where higher surface instability will exist. Still a chance of strong to isolated severe storms Tuesday ahead of an approaching cold front, but this system will also bring needed rainfall. The higher amounts of 0.5-1.5 inches are expected across southeast GA and the Suwannee River Valley where a surface flow is expected to form and track northward along the front. Less rainfall (generally < 0.50 inches)is expected across the remainder of northeast Florida with this system. The severe thunderstorm threat will focus mainly across southeast GA from the coast to locations south of Waycross and the Suwannee River Valley Tuesday morning, then shift across northeast Florida into Tuesday afternoon, with dry conditions by Tuesday evening. This event is characterized by a high shear-low CAPE environment, with impressive 0-6 km bulk shear of 50-70 kts and a strong 40-50 kt 850 mb low level jet, but limited CAPE/instability with MU CAPE generally 200-500 J/kg. The main isolated strong to severe storm hazards will be gusty winds of 50-70 mph and brief, isolated tornadoes. Even outside of storms, non-convective wind gusts of 30- 40 mph will be possible at times through early afternoon, mainly across northeast FL where higher, but meager, surface instability will be ahead of the broken squall line, while a more stratiform rainfall across southeast GA and associated cloud cover will limit surface based instability and overall severe storm threat, especially for locations north of Waycross. Temperatures trend generally above normal in the 70s to near 80 across much areas except north of Waycross toward the Altamaha River where 60s will prevail under cloud cover and rainy conditions. Mild overnight lows will range in the 50s and 60s Monday night trailing the lifting warm front, then a 10-15 degree cool down Tuesday night trailing the frontal passage with lows back into the upper 30s to 40s north of I-10 and 50s south. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Dry and seasonably cool Wednesday and Thursday with inland frost potential across SE GA Thursday morning with weak high pressure dominating north of the region. Overall trending with a more progressive and wetter pattern mid to late week with approaching and stalling frontal systems. Rain chances return Friday and continue into the weekend with mild temperatures warming back above average values. A chance of thunderstorms returns as early as Friday with another potential wave of low pressure from the Gulf. Opted to leave thunderstorms out of the official forecast as models are having a hard time resolving the evolution of this system. Main takeaway is that fronts will be edging closer and potentially stalling near to over the local area, which will bring more needed rainfall. Latest climate site rainfall deficits since Sept 1st are 6-9 inches at Alma, Jacksonville and Craig Airfield to 3-4 inches at Gainesville. && .AVIATION /06Z SUNDAY THROUGH 06Z MONDAY/... VFR conditions will be in place through the forecast period with calm and variable winds overnight and easterly winds developing in the late morning. && .MARINE... A coastal trough will break down Sunday into Monday as a weakening front approaches from the north then begins to stall just north of the local waters into Monday night. This front will morph into a lifting warm front ahead of a stronger frontal system as it approaches late Monday into Tuesday. Southerly winds increase Tuesday near Small Craft levels with a chance of thunderstorms. The front is expected to push south of the local waters late Tuesday, then high pressure builds northwest of the region mid-week as winds subside below Advisory levels. Rip Currents: SE GA: Low risk today, moderate Monday. NE FL: Moderate risk today, high risk Monday. && .FIRE WEATHER... Moisture is gradually increasing across the local area under easterly winds. A few coastal sprinkles are possible today, otherwise dry conditions continue, but with higher minimum humidity compared to yesterday. Passing showers are possible Monday as a warm front lifts across the area. An approaching cold front will bring needed rainfall Tuesday with a chance of strong thunderstorms capable of gusty winds and lightning. Gusty southwest winds outside of thunderstorms are expected Tuesday. Rainfall will end Tuesday evening as the front presses south of the area. Dry conditions are expected by Wednesday with lower humidity under north winds. FOG POTENTIAL AND OTHER REMARKS...Inland patchy fog is possible this morning and again Monday morning. Gusty and erratic winds will occur from thunderstorm activity Tuesday. Need rainfall is expected, but lightning strikes may cause wildfires due to dry fuels. && .PRELIMINARY POINT TEMPS/POPS...
