Area Forecast Discussion National Weather Service Jacksonville FL 804 AM EDT Fri May 10 2024 ...New AVIATION... .NEAR TERM... Issued at 313 AM EDT Fri May 10 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 Rather complex weather pattern for today as several rounds of strong to severe storms expected ahead of cold frontal passage with 1st one arriving during the morning hours, with a secondary storm complex this afternoon moving front NW to SE across the region, followed by a lingering strong to severe storm threat with the actual cold frontal passage across SE GA during the late afternoon hours and NE FL during the evening hours before finally pushing south of the region around midnight tonight. Damaging winds remain the main threat from these storm complexes as they move quickly through, but large hail and/or isolated tornadoes cannot be ruled out. Training of storms will lead to excessive rainfall potential as well with SE GA counties under the main threat of localized flooding due to wetter antecedent conditions and the heavy rainfall that already occurred Thursday afternoon, while NE FL missed out on most of the heavy rainfall yesterday, so should be able to handle the waves of heavy rainfall with any localized flooding issues confined to urban areas. Max temps will be tricky as the wave of morning storms will hinder daytime heating but a break in between the 2 storm complexes should still lead to highs in the lower 80s across SE GA, while a bit more sunshine ahead of the storm complexes across NE FL should lead to highs mainly in the mid/upper 80s, while some lower 90s may still be reached mainly across Marion/Putnam/St. Johns and Flagler counties. Following the last round of strong to severe storms with the cold frontal passage this evening, expect clearing skies during the overnight hours as winds become North around 10 mph and a cooler/drier airmass filters into the region towards morning with lows near 60 across SE GA and in the mid/upper 60s across NE FL by sunrise Saturday morning. && .SHORT TERM... (Saturday through Sunday night) Issued at 313 AM EDT Fri May 10 2024 The cold front will have essentially cleared the region by the start of Saturday, with weak high pressure building in throughout the day. The pressure gradient behind the front will not be particularly strong, and therefore winds will not really increase diurnally, and in fact may subside a bit throughout the day. The more northerly component with the wind should allow a bit of a sea breeze to develop, though will likely not penetrate much further inland than the I-95/St. Johns River corridor. Otherwise, a mostly sunny and seasonably warm day, near to slightly above 80 north and upper 80s to near 90 south, dropping into the upper 50s to low/mid 60s Saturday Night. Broad high pressure moves more overhead on Saturday Night and through Sunday, which will persist fair weather and light winds to end the weekend with just some high clouds starting to fill in overhead. A sea breeze will develop once again with the light winds during the afternoon, with temps topping out in the 80s before the boundary moves across eastern areas. More cloud cover will result in a bit milder lows Sunday Night, generally 60s to near 70 by the coast and St. Johns River. && .LONG TERM... (Monday through Thursday) Issued at 313 AM EDT Fri May 10 2024 High pressure moves offshore Monday, with a much more unsettled pattern looking to take shape for most of this period. A frontal system approaches the area with a warm front passage on Monday, followed by the trailing cold front Tuesday and into Wednesday. The boundary looks to stall almost directly over the CWA around the Wednesday/Thursday time frame, with several shortwaves moving across the area and maintaining chances for showers and t'storms before more of a "kicker" front approaches towards the end of the week. Temperatures start this period near to slightly below average with the unsettled weather, then towards near to slightly above average by Wednesday/Thursday. && .AVIATION... (12Z TAFS) Issued at 804 AM EDT Fri May 10 2024 A line of storms and showers will move through the area this TAF period as a cold front pushes through. Lower cigs/vsbys as storms pass over TAF sites, with gusty winds up to 30knots possible. Conditions will begin to improve from 03-06Z as the cold front moves through the area. && .MARINE... Issued at 313 AM EDT Fri May 10 2024 Offshore Southwest to West flow will remain at SCEC (Small Craft Exercise Caution) levels (15-20 knots) ahead of the cold frontal passage Today into this evening with the main marine hazard with strong to severe storms with damaging wind threat impacting the waters in several waves through this evening. Winds shift to the North at SCEC levels after midnight tonight behind the cold frontal passage and spread across the local waters. These winds become onshore/NE on Saturday and weaken to 10-15 knots as the weak high pressure ridge builds over the waters for the weekend with weak pressure gradient and No headlines expected with local sea breezes during the afternoon hours. The old frontal boundary lifts back to the North as a warm frontal boundary on Monday and stalls across the local waters on Tuesday as several waves of low pressure track along this feature. Increasing SE winds on Monday to possible Small Craft Advisory levels will shift to South and Southwest on Tuesday as the waves moving along the frontal boundary with a more unsettled pattern of showers and storms at times, with heavy rainfall and gusty wind threat at times early next week. Rip Currents: Low to Moderate risk of rip currents expected Today through the weekend with surf/breakers around 2 feet, before onshore/SE flow increases on Monday with a potential for solid Moderate to High Risk of rip currents. && .PRELIMINARY POINT TEMPS/POPS...
