Area Forecast Discussion National Weather Service Jacksonville FL 314pm EDT Monday Oct 14 2024 ...TIDAL FLOODING CONTINUES IN THE ST JOHNS RIVER BASIN... ...COOLER TEMPERATURES THIS WEEK... Near Term Issued at 314pm EDT Monday Oct 14 2024 For the latest NE FL and SE GA Daily Key Messages please visit: https://www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf Tonight, cooler trailing the nighttime frontal passage across SE GA where lows will fall into the lower 50s with upper 50s to lower 60s expected across NE FL where some moisture pooling along and near the front could cause some transient fog and low stratus to form just ahead of the surface front. Main weather impacts continue to be dangerous surf zone conditions where a HIGH RIP CURRENT RISK continues through this evening as well as Tidal flooding along the NE FL Atlantic coast and persisting in the St. Johns River basin. .SHORT TERM... (Tuesday through Wednesday night) Issued at 314pm EDT Monday Oct 14 2024 A weakening frontal boundary will be over north-central FL early Tuesday morning will gradually shift southward. Meanwhile, a reinforcing dry front driven by a strong mid to upper level trough will shift southward through the SE U.S. bringing and even colder and drier airmass to the region. This secondary front will push from north to south through the area Tuesday night. With minimal moisture, this front may bring some sprinkles to north-central FL early Wednesday morning but overall will be an increase in cloud cover. Strong surface high pressure builds southward down the MS River Valley and into the SE U.S. by Wednesday night. Breezy northerly winds develop in the wake of this front with winds 15-20 mph gusting up to 30 mph are possible, mainly along the NE FL coast. A north-south gradient prevails on Tuesday with highs ranging from the mid 70s to mid 80s and lows dropping into the low 50s to low 60s. Wednesday will be the coldest day of the week with highs only reaching the mid 60s to low 70s. Clearing and subsidence will allow for temperatures to drop Wednesday night into the low 40s across inland SE GA to around 60 along the NE FL coast. Long Term (Thursday through next Sunday) Issued at 314pm EDT Monday Oct 14 2024 Upper trough over the eastern seaboard and ridging over the MS river basin will maintain northerly flow aloft and cold air advection for Thursday. A gradual warming and moistening trend is expected through the rest of the week and weekend as high pressure remains over the southeast CONUS and a mid level ridge settles in overhead. Subsidence and a dry airmass will continue a mostly rain-free week. Although, a shower may be possible along the NE FL coast this weekend. Breezy east-northeasterly winds develop as the local pressure gradient remains tight. The onshore flow combined with higher astronomical tides will lead to at least minor coastal flooding concerns for the area beaches as well as the Intracoastal Waterway and the St Johns River basin. Marine Issued at 314pm EDT Monday Oct 14 2024 A dry cold front will move south across the waters tonight, then a reinforcing dry front will move across the waters Tuesday night. High pressure builds northwest then north of the local waters Wednesday and Thursday with a return of Small Craft Advisory conditions across local waters. The high strengthens northeast of the region Friday into Saturday with a continuation of Small Craft conditions and an increase in winds, seas and shower potential as a coastal trough develops offshore. Rip Currents High risk for rip currents for northeast FL beaches and moderate risk for southeast GA continue today. Surf zone width may be unusually wide due to the sandbars, with roughed out rip current channels likely persisting this week. Hydrology Issued at 314pm EDT Monday Oct 14 2024 Tidal Flooding: Removed the coastal counties from the Coastal Flood Advisory and adjusted the Advisory to only focus across the St. Johns River Basin from downtown JAX to the Shands Bridge due to minor tidal inundation around high tide. Continued the Coastal Flood Warning for moderate tidal flooding for Putnam and Flagler counties. Water levels will gradually rise late in the week as high astronomical tides and a nor'easter combine. River Flooding: Southeast GA: Minor river flooding continues to fall along the Alapaha, Altamaha and Satilla. Minor flooding continues along the Santa Fe at Three Rivers. NOAA Jacksonville FL Office: Watches - Warnings - Advisories FL...Coastal Flood Advisory until 5am EDT Wednesday for FLZ033-132- 325. Coastal Flood Warning until 5am EDT Wednesday for FLZ038-137. High Rip Current Risk until 8pm EDT this evening for FLZ124-125- 133-138. GA...None. AM...None. |
