| Area Forecast Discussion National Weather Service Jacksonville FL 206pm EDT Monday April 29 2024 .SHORT TERM... (Tuesday through Wednesday night) Issued at 200pm EDT Monday April 29 2024 Tuesday, a weak upper level trough makes its way into the area providing some instability to the region. High pressure off the Atlantic coast will move further east through the week shifting winds to southerly and allowing the Gulf coast and Atlantic sea- breeze to make their way inland in the afternoon, converging along US 17. This convergence along with the weak upper level instability provides slight chances (15-25%) for rain and storms in the afternoon and evening with higher chances for SE GA (35-40%). Temperatures will be in the mid to upper 80s inland staying cooler along the coast. Overnight lows will be in the mid 60s. Wednesday, The weak upper level tough has moved east and a surface high approaches from the west shifting winds to northerly by the afternoon as it approaches. Northerly winds will allow for the sea-breeze from the Gulf and Atlantic to make its way inland again and converge but with the absence of some upper level instability, rain chances will be a bit lower especially for SE GA. Expect temperatures in the upper 80s inland with temperatures in the mid 80s along the coast. Long Term (Thursday through next Monday) Issued at 200pm EDT Monday April 29 2024 The upper level ridge continues to build into the area into Friday drying out the air aloft and reducing the chances for any precipitation for Thursday and Friday. Mostly clear skies will allow temperatures to reach into the upper 80s and low 90s Thursday. Mostly cloudy skies Friday will keep temperatures in the upper 80s, remaining in the low to mid 80s along the coast. Chances increase for isolated afternoon showers and thunderstorms for the weekend as an upper level trough makes its way through the region and a cold front pushes more moisture into the area from the west. Temperatures will be in the mid to upper 80s inland with overnight lows will be in the low to mid 60s. Marine Issued at 200pm EDT Monday April 29 2024 Breezy southeast winds will continue into Tuesday morning and then become more southerly into Wednesday as a weak frontal system moves into the region. A few showers or a thunderstorm possible Tuesday into Wed, mainly offshore waters, associated with the weak frontal system/upper level disturbance moving into the area. Otherwise, winds mostly up to about 15 kt and seas near 3-5 ft, possible touching 15-20 kt and seas up to 4-6 ft briefly but no headlines anticipated at this time. A cold front is then expected to enter the southeast states by Saturday night and Sunday, possibly bringing a chance of showers and thunderstorms to our region by late in the upcoming weekend. Rip Currents Breezy onshore winds and elevated surf conditions will create a high end moderate rip current risk at all area beaches rest of today. A moderate risk will likely continue on Tuesday as breezy onshore winds develop during the afternoon hours and breaker heigheights remain similar to today. The risk may decrease towards midweek as surf heigheights subside. NOAA Jacksonville FL Office: Watches - Warnings - Advisories FL...None. GA...None. AM...None. |
