For the latest NE FL and SE GA Daily Key Messages please visit: https:/www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf - Moderate Risk of Rip Currents at Area Beaches Today - Waves of Showers and Thunderstorms through Early Next Week. Widespread 1-3 Rainfall Totals Forecast through Monday, with Localized Totals. Daily Marginal Risk of Flooding, especially in Urban and Flood-Prone Areas && .UPDATE... Showers and Thunderstorms have largely ended across the area, a little earlier than expected with exception of a band of showers that have formed along a boundary near Fernandina Beach/Amelia Island into the coastal waters where a little instability lingered from this afternoon. Otherwise, a mild night is expected with low in the low 70s inland with a few spots just below 70 over SE GA and warming to the mid 70s along the coast. Patchy fog and low stratus will develop where partial clearing and calm winds overlap (mainly along and north of I-10 into SE GA) as a front weakens over the area tonight with another front arriving from the north late Sunday morning. && .AVIATION /00Z SUNDAY THROUGH 00Z MONDAY/... VFR ceilings across the TAF sites will continue through 06Z along with isolated to scattered showers. A weak frontal boundary remains across the area with a lull in showers late tonight away from the coast with low ceilings developing at VQQ and GNV after 06Z with tempo restrictions for LIFR/VLIFR ceilings below 0.5 kft from 08Z to 12Z. Light west to southwest winds persist around 5 knots near the coast turning calm inland after 06Z. The frontal boundary will dissipate by Sunday morning as another front moves in from the north and sinks into the GA coast with showers increasing after 14Z. As the front moves south along the coast, winds will turn from westerly to east northeasterly 6-10 knots as weak high pressure moves from the Mid Atlantic states to the NC coast, while inland winds remain westerly. After 18Z, strong diurnal heating will prompt VCTS with SHRA at SSI with earlier front arrival. PROB30 groups for MVFR ceilings and IFR visibilities from heavy downpours. && .MARINE... A stationary frontal boundary situated over the Georgia waters will dissipate tonight with scattered showers and thunderstorms through midnight. Another frontal boundary will push into the southeastern states on Sunday morning as high pressure builds southward from the Great Lakes and Mid-Atlantic states. Additional rounds of showers and thunderstorms are forecast from Sunday through Tuesday evening as this front stalls over our area before a stronger cold front pushes southward across our local waters on Tuesday night. Northeasterly winds will surge in the wake of this frontal passage on Tuesday night as high pressure building over the Ohio and Tennessee Valleys wedges down the southeastern seaboard, creating Small Craft Advisory conditions from late Tuesday night through at least Wednesday night throughout our local waters. Breezy onshore winds and elevated seas are expected through Thursday night as high pressure gradually weakens over the southeastern states. Rip Currents: A low to locally moderate risk today with surf of likely to be below 2 ft with buoys showing 1.5 ft seas. There is a lingering wind-sea swells of about 9 seconds. The risk may begin to rise back up to moderate to locally high Sunday afternoon into Monday due to onshore flow and increased surf. && .PRELIMINARY POINT TEMPS/POPS...
