062 FXUS62 KJAX 300517 AFDJAX Area Forecast Discussion National Weather Service Jacksonville FL 117 AM EDT Thu May 30 2024 ...New AVIATION... .NEAR TERM... Issued at 200 PM EDT Wed May 29 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 The weakening cold front is over south central Florida this afternoon and will remain fairly stationary through tonight or perhaps dissipate over South Florida as high pressure builds to the north of the region. As a result, NWLY flow will continue over the region with markedly drier air moving over the region with dewpoints dropping into the mid 50s inland to lower 60s at the coast this late afternoon and early evening. By tonight a dry airmass will be in place (PWATs < 1 in. north of I-10, and slightly above 1" south of I-10)) to settle across the region. Lows tonight will "cool" into the low to upper 60s to near 70 at the beaches and along the St. Johns in downtown JAX with light north winds or nearly calm wind. && .SHORT TERM... (Thursday through Friday night) Issued at 200 PM EDT Wed May 29 2024 Dry conditions will continue area-wide Thursday as a weak front moves south of the area. High temperatures will reach the upper 80s to mid 90s, however with lower dewpoints, heat indices will max out in the lower to mid 90s. Northerly steering flow will linger into Friday, although an east coast sea breeze will fill in in the afternoon, bringing moisture back into northeast Florida. Rain chances will be limited to 15-30%, mainly inland south of I-10, and some isolated thunderstorms cannot be ruled out. Similar high temperatures to Thursday expected Friday, with slightly cooler coastal temps due to the afternoon sea breeze. && .LONG TERM... (Saturday through next Wednesday) Issued at 200 PM EDT Wed May 29 2024 High pressure over the Carolina`s will begin to sink southeastward this weekend, promoting onshore flow locally. PWATs remain pretty low on Saturday limiting rain chances, by Sunday they will increase near 1.5 inches (still below normal). Breezy onshore winds and an afternoon sea breeze will allow for isolated to scattered precip chances on Sunday area-wide. `Cooler` high temperatures forecast for this weekend, ranging from the lower 80s to lower 90s with the lower values along the coast. Temperatures will slowly heat back up during the work week with daily afternoon scattered rain/thunderstorm chances. && .AVIATION...
