Area Forecast Discussion National Weather Service Jacksonville FL 157 PM EDT Wed Jun 11 2025 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE, FIRE WEATHER... .NEAR TERM...(through Tonight)... Kind of a classic sea breeze merger set up this afternoon. The one added feature(s) are the differential heating (instability gradients) that have resulted in enhanced convergence on the edges of a thin belt of cirrus across NE FL. Despite the enhance convergence along those features, the dominant lifting mechanism will be the Atlantic sea breeze and its interaction with the St Johns River breeze and thunderstorm outflow. Southerly flow is allowing both the Gulf and Atlc sea breeze to move inland. The most robust convection is expected late this afternoon and during the evening as sea breezes collide. Storm motion may be slow, especially later in the afternoon and evening as the Gulf and Atlc sea breezes collide between US Highway 301 and I-75. Outside of converging-outflow initiation, storm- relative winds will be more likely to favor new thunderstorm development along the southern edges of outflow, also at slow storm motions around 5 mph or less. This is underscoring the potential for a localized flash flooding threat, mainly along the converging sea breezes. Based on the deep moisture available, some thunderstorms may produce instantaneous rain rates of 3-5"/hour. Despite relatively cool mid levels, upper level warming and lack of shear aloft will lead to a low chance of hail with storms today; however, strong downbursts and gusty winds are again possible with steep near-surface lapse rates. Temps may squeeze out another degree or two, pushing into the low 90s, before convection/sea breeze begin. Tonight, mostly clear skies will lead to temperatures in the low 70s inland and upper 70s at the beaches. && .SHORT TERM...(Thursday through Friday night)... Southerly/southeasterly winds will allow for enhanced moisture (PWATs near 1.75-2.0") and both the Gulf and Atlantic sea breezes to develop and push inland. Expect the sea breezes to collide generally between I-95 and I-75, with interactions sparking up thunderstorms, some of which may become strong. Primary concern will be heavy rainfall, after several days of downpours there is potential for localized flooding. The onshore breeze will keep coastal locations in the mid to upper 80s, but inland highs will climb into the lower 90s. && .LONG TERM...(Saturday through next Wednesday)... Daily convection across the area is expected, with the highest coverage in the afternoons and evenings as sea breezes interact inland. By Monday, steering flow shifts back to southwesterly, allowing for the Gulf sea breeze to dominate, enhancing storm potential closer to the east coast. Temperatures this weekend will be near normal, highs in the upper 80s to lower 90s. By Monday and Tuesday, it will get hotter with highs in the lower to mid 90s with max heat indices approaching 100-105 degrees. && .AVIATION...(18Z TAFS) Issued at 114 PM EDT Wed Jun 11 2025 TSRA beginning to initiate along the sea breeze as of 17z, which has pushed beyond coastal terminals (KSGJ/KSSI/KCRG). Heavy TSRA will be capable of erratic outflow gusts and downbursts in addition to low vsby. TSRA impacts at KJAX/KVQQ beginning around 19z and around 21z at KGNV. Convective activity will fade and drift off to the NW this evening. Away from TSRA influence, VFR conditions continue with cumulus bases around 3-6 kft. Quiet, VFR conditions overnight with light winds. Similar trends, with perhaps an earlier/faster easterly sea breeze. && .MARINE... Winds continue to shift to southeasterly as a ridge axis lifts northward. The Bermuda ridge will lay across the waters through the rest of the week and continue onshore flow. Offshore flow will return this weekend as another front approaches and stall to the northwest. Daily thunderstorms are possible through the week but coverage will likely be more limited until offshore flow returns this weekend. Rip Currents: Moderate risk continues through the end of the week. Rip current development more likely during the afternoon with the sea breeze. && .FIRE WEATHER... Daily showers and embedded thunderstorms are forecast each day this week, with the highest coverage being in the afternoons and evenings. Winds will stay more southerly/southeasterly through the end of the week, allowing the Atlantic sea breeze to push inland and interact with the Gulf sea breeze, popping up storms. Highest coverage of showers and stronger storm development will generally be between I-75 and I-95 Thursday. Dispersion will be fair to good on Thursday and Friday. && .PRELIMINARY POINT TEMPS/POPS...
