Area Forecast Discussion National Weather Service Jacksonville FL 854 AM EDT Sat May 20 2023 ...New UPDATE... .UPDATE... Issued at 841 AM EDT Sat May 20 2023 A light West to Northwest steering flow and drier airmass aloft will keep rainfall chances below normal once again this afternoon. Precipitable Water amounts have fallen to around 1.25" across SE GA, but remain closer to 1.5" across NE FL where the Gulf/Atlantic sea breeze fronts will push inland to kick off some widely scattered showers/storms this afternoon across inland NE FL, mainly south of the I-10 corridor, and severe storms are not expected, but one or two strong storms with gusty winds possible along with locally heavy rainfall threat due to the slow storm motion in Putnam/Alachua/Marion county vicinity late in the day as the sea breeze fronts merge. Max temps generally in the middle 80s across SE GA and upper 80s/near 90 across inland NE FL, with slightly cooler temps along the Atlantic Coast. A few evening storms over inland NE FL until sunset, then partly to mostly cloudy skies overnight with mid/high clouds pushing in ahead of approaching frontal boundary, and even some widely scattered pre frontal showers/isolated storms possible across inland SE GA towards morning. Otherwise the usual patchy late night low stratus/fog over inland areas with lows in the mid/upper 60s inland and lower 70s along the Atlantic Coast. && .NEAR TERM... (Through Tonight) Issued at 241 AM EDT Sat May 20 2023 Weak upper ridge will move over the forecast area through Tonight, leading to a drier short term period with only isolated to widely scattered afternoon showers/t-storms mainly over our southern counties in n-ctrl FL. High temperatures will be in the 85-90 range inland...lower 80s coast. Partly cloudy skies Tonight will lead to low temperatures in the 65-70 range. && .SHORT TERM... (Sunday through Monday night) Issued at 241 AM EDT Sat May 20 2023 Frontal boundary will press down from out of the northwest on Sunday leading to scattered to numerous thunderstorms building throughout the day as the frontal boundary interacts with the local diurnal sea breeze pattern. Frontal boundary will stall to the north for this period with widespread showers with thunderstorms building throughout the forecast area on Monday. Daily high temperatures will drop from out of the lower 90s on Sunday down to below average levels on Monday with max temps in the upper 70s and lower 80s through much of the forecast area. Overnight low temperatures will similarly drop from out of the upper 60s and lower 70s down into the mid 60s for inland areas. && .LONG TERM... (Tuesday through Friday) Issued at 241 AM EDT Sat May 20 2023 Low pressure center is anticipated to develop along the stalled frontal boundary by Tuesday resulting in breezy northerly- northeasterly winds over the forecast area through the rest of the week with initially more widespread convective developments expected for the beginning of the forecast period. The frontal boundary may push across the forecast area by the latter portion of the week as the area of low pressure moves off to the northeast leading to less active convection on Thursday. Daily high temperatures will trend below average through the end of the week. Increased risks for rip currents are likely during this period along with a possibility for further coastal impacts. && .AVIATION... (12Z TAFS) Issued at 738 AM EDT Sat May 20 2023 Low LIFR CIGS/IFR VSBYS at GNV early this morning, otherwise diurnal heating will develop some MVFR CIGS at TAF sites through the mid morning hours (15Z or so). Not quite enough moisture for any significant rainfall today, except for some possible VCSH at VQQ and VCTS at GNV in the 20-24Z time frame, otherwise mainly SCT diurnal Cumulus clouds with Easterly winds from the Atlantic sea breeze in the 8-12 knot range. Mainly VFR conds after sunset with light and variable winds and some SCT/BKN mid to high clouds. Low level moisture and near calm winds late in the period will allow for fog/low stratus to develop at LIFR levels at GNV/VQQ after 09Z, with some MVFR VSBYS possible closer to the Coast at JAX. && .MARINE... Issued at 241 AM EDT Sat May 20 2023 Weak High pressure will build north of the region Today. The next front will approach from the north Tonight into Sunday, then shift southward over the waters Sunday night through Monday, while high pressure strengthens north of the region. This will lead to stronger onshore flow through the middle of next week. Scattered showers and thunderstorms during the weekend will become more numerous during the early part of next week. Rip Currents: High end Moderate this afternoon and Sunday for NE FL and SE GA. Stronger onshore flow pattern early next week will yield high risk then. && .PRELIMINARY POINT TEMPS/POPS...
