National Weather Service Jacksonville FL 255 AM EDT Sat Apr 20 2024 ...ISOLATED SEVERE STORM POSSIBLE OVER PARTS OF SOUTHEAST GA LATE TODAY... ...NEAR RECORD HEAT TODAY... ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE, CLIMATE... .NEAR TERM... (Today through Tonight) Issued at 252 AM EDT Sat Apr 20 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 Currently, temps are in the 60s to around 70 with light west winds. Dewpoints in the 60s and the light winds combined with subsidence producing some patchy radiation and advection fog over the inland northeast FL area. This fog will shift eastward over course of the next few hours. Flow aloft is nearly zonal, but an upper level trough over the southwest CONUS will translate eastward, and attempt to phase with energy across the northern U.S. embedded in a long wave trough. Heights across the southeast U.S. are expected to decrease and models show weak embedded shortwaves moving into our area in mainly zonal flow this afternoon and evening ahead of a cold front. The cold front looks to be positioned across SC to central GA to south central AL this morning, and will move slowly southeastward through tonight into our area. The front may drop to around the FL/GA border by late tonight. The frontal boundary combined with lift from shortwave energy will support isolated to scattered convection. Some potential for a strong storm or two mainly over northern most zones, given adequate effective shear of up to 25-30 kt and MLCAPE reaching upwards of about 800-1400 J/kg late today and tonight. Main threats will be strong gusty winds and marginally severe hail. Timing may be more toward evening hours and possibly til about 1-2 AM tonight. SPC has highlighted a marginal risk of severe storms from Waycross northward through tonight. Higher than normal max temps today with upper 80s to possibly lower 90s in a few spots and will be close to record levels. Notes in the climate section. Tonight, isolated to scattered convection expected through the evening over the north zones, with activity shifting west to east. Expecting a downward trend in intensity and coverage after midnight. Some patchy fog possible overnight but looks fairly low chances at this time. Lows tonight mainly in the 60s, warmest readings over the north portions due to clouds and some precip.
