| Area Forecast Discussion National Weather Service Jacksonville FL 717pm EDT Wednesday May 8 2024 .SHORT TERM... (Thursday through Friday night) Issued at 315pm EDT Wednesday May 8 2024 Breezy southwest winds will be in place ahead of a cold front moving south to the area. Ahead of the cold front, a line of showers and storms will begin to move across the area on Thursday afternoon/evening. With the latest update, Storm Prediction Center has placed areas north of Waycross, GA into an Enhanced Risk (level 3 out of 5) for severe thunderstorm development, with the primarily concern of damaging wind gusts (with gusts from 50-70 mph), along with Hail up to 1" as well as the possibility of isolated tornadoes as the line of storms moves through SE GA into NE FL. Storms will begin to move offshore by the early evening hours, allowing for a respite from the more severe storms during the overnight hours. By Friday morning, activity will begin to increase as the cold front begins to move across the area. The majority of the area will be in a Marginal Risk (1 out of 5) for severe thunderstorm development, again damaging wind gusts will be the main concern for storms that do develop. Activity will begin to dwindle as evening arrives, as the cold front will have move through to the south of NE FL. Before the cold front's arrival, Thursday's daytime temperatures will again reach near record levels as most areas will see daytime highs in the mid 90s, leading to Heat Index values ranging from the mid 90s to 100s. Temperatures will trend down a bit on Friday as the front begins to move through the area, locations north of the I-10 corridor will top out in the mid to upper 80s, while locations along the St. Johns River Basin will top out in the lower 90s. Long Term (Saturday through next Wednesday) Issued at 315pm EDT Wednesday May 8 2024 The weekend will be marked by a quiet weather pattern with high pressure beginning to build into the area after the cold front's passage. The next round of activity currently looks to move in during the early portion of the following week as high pressure begins to weaken over the area. The cold front will usher in cooler temperatures through the weekend and into next week, as daytime temperatures will be in the upper 70s to lower 80s over SE GA and from the lower 80s to upper 80s. Marine Issued at 315pm EDT Wednesday May 8 2024 Atlantic high pressure will continue to extend its axis westward across the Florida peninsula through Thursday night. Southerly evening wind surges are expected this evening and again on Thursday evening, bringing wind speeds up to Caution levels of 15 to 20 knots for the offshore waters. Seas of 2-4 feet will prevail through Thursday night for the near shore waters, with 3-5 foot seas prevailing offshore. Meanwhile, a strong cold front will enter the southeastern states on Thursday night, with chances for showers and thunderstorms increasing ahead of this boundary from Thursday afternoon through Friday evening. A few rounds of strong to severe thunderstorms will be possible during this time frame, with damaging wind gusts, hail, and frequent lightning strikes possible within any severe thunderstorms that develop. The cold front will cross our local waters on Friday afternoon and evening, with high pressure then gradually building to the north of our area later this weekend and early next week in the wake of this frontal passage, resulting in prevailing onshore winds during this time period. Seas of 2-4 feet will prevail both near shore and offshore from Friday through the weekend. Rip Currents Breezy onshore winds developing this afternoon and again on Thursday afternoon will combine with a northeasterly ocean swell to create a moderate rip current risk at all area beaches on both afternoons. Breezy offshore winds on Friday should reduce the risk to low at all area beaches. Fire Weather Issued at 315pm EDT Wednesday May 8 2024 Southwesterly transport winds will strengthen further on Thursday, creating high daytime dispersion values for most locations east of the Interstate 75 corridor during the afternoon hours. Otherwise, a hot and dry air mass over our region will result in minimum relative humidity values falling to around 35 percent at most inland locations this afternoon, with minimum values again around 35 percent forecast for most locations east of I-75 on Thursday afternoon. Strong west-southwesterly transport winds on Friday will again create good to marginally high daytime dispersion values, except for high values across portions of north central FL. A few rounds of strong to severe thunderstorms will be possible from Thursday afternoon through Friday evening, with damaging wind gusts, hail, and frequent lightning strikes possible within any severe thunderstorms that develop. Surface and transport winds will shift to northwesterly on Saturday, with a cooler and drier air mass dropping relative humidity values to the 30-35 percent range at inland locations on Saturday afternoon.
