Episode narrativeepisode_narrativeA wet, unsettled weather pattern continued over the area with a surface front across central in the morning that lifted north into the afternoon as a warm front as a surface low developed along the boundary in the eastern GOMEX and approached Apalachee Bay. Rainfall and isolated thunderstorms continued across NE FL near the lingering surface front in the morning, then as the front retreated northward toward I-10 into the afternoon, the potential for thunderstorms across NE FL expanded northward |within the warm sector. There was a window for severe storm potential in the afternoon across NE FL where enough instability (1000-1500 J/kg MLCAPE) phased with a 35-40 kt 850 mb jet under about 40-50 kts bulk shear with HREF with STP guidance near 1-1.3 units. These ingredients favor strong wind gust potential in |isolated severe storms during this time frame (40-60 mph gusts) and a low threat of isolated, brief tornadoes with Effective SRH |200 m2/s2.
