Jacksonville is heading into a soggy weekend, with showers and thunderstorms building Saturday before a wetter stretch settles in for much of next week. The city started Saturday in the upper 70s under very humid skies, with a forecast high near 87 degrees and showers and thunderstorms remaining in the forecast. The National Weather Service’s Jacksonville-area page forecast a high near 87 degrees.
Storm Chances Build Saturday Afternoon
Showers and thunderstorms are expected to become more likely this afternoon. Jacksonville’s high is forecast near 88 degrees, with an 80% chance of precipitation and southeast winds around 3 to 8 mph. The current National Weather Service forecast gives the updated high, rain chance and wind range.
Showers and thunderstorms remain possible Saturday night as additional rounds of heavy downpours are expected across the weekend. Jacksonville’s temperature is forecast to fall to around 76 degrees overnight, with little relief from the humidity after sunset. The National Weather Service’s weekend outlook calls for additional downpours, while its hourly Jacksonville forecast shows overnight temperatures near 76.
Sunday And Monday Look Even Wetter
Sunday remains unsettled, with showers and thunderstorms in the forecast and heavy downpours possible. Repeated rainfall could cause localized flooding, especially where storms pass over the same area. The National Weather Service expects additional heavy downpours and a localized flood risk through the weekend.
The rain threat extends beyond individual afternoon storms: the National Weather Service expects several inches of rain over the next several days, with localized flooding possible each day. Repeated downpours can quickly overwhelm low spots and drainage areas, so the flood concern could persist even when rain lets up between storm bands. The Jacksonville-area forecast highlights the multi-day rainfall and localized flooding risk.
Monday remains thoroughly unsettled, with showers likely and thunderstorms developing later in the day. The high is forecast near 81 degrees, with a 90% chance of precipitation. The current National Weather Service forecast gives Monday’s high and rain chance.
Coastal Conditions Turn More Dangerous Tuesday
The coastal pattern is forecast to strengthen Monday night, when strong, gusty northeast winds are expected to arrive. Tuesday’s high is forecast near 79 degrees, with showers and thunderstorms likely; breezy conditions and showers are expected to continue Wednesday, with a high near 77. The current Jacksonville-area forecast lists Tuesday’s temperature and rain chance, and the NWS discussion forecasts stronger northeast winds beginning Monday night and gale conditions over Atlantic waters Tuesday and Wednesday.
That shift could bring rough surf, stronger rip currents and beach erosion concerns, with tidal flooding also possible along the Atlantic coast, the Intracoastal Waterway and tidal portions of the St. Johns River. The latest outlook calls for dangerous beach conditions to persist into the latter half of next week, so swimmers and boaters should check conditions before heading out.
Beach and marine hazards are expected to build after the weekend’s moderate rip-current risk. The National Weather Service forecasts strong, gusty northeast winds beginning Monday night, with gale conditions likely over Atlantic waters Tuesday and Wednesday. It also identifies a risk of substantial beach erosion and moderate tidal flooding Tuesday through Thursday along the Atlantic coast, Intracoastal Waterway and tidal tributaries. The Jacksonville forecast discussion outlines the timing of those coastal hazards.
Stormy Weather And Coastal Winds Bear Watching
The combination of repeated heavy rain and increasing coastal winds deserves attention. The update adds a more serious next-week threat to the stormy weekend pattern outlined in Hoodline’s earlier forecast.
