Issued at 309 PM EDT Thu Jun 13 2024 A shortwave trough axis continues to propagate westward as tropical moisture is pulled northward across the FL peninsula. This is in contrast to drier air being pulled southward over the N FL peninsula. Heavy rainfall continues across SWFL in response as isolated to scattered diurnal convection starts to develop over Central and N Florida. The expectation is for heavy rainfall over SWFL to wind down for at least a period here in the next hour or two. The atmosphere will then need some time to recover before additional rainfall redevelops again overnight and into tomorrow. Another round of heavy rainfall is possible over a more confined section of SWFL. Considering how much rain has already fallen in this same area, this necessitated the extension of the Flood Watch through tomorrow in Charlotte and Lee Counties. However, lower totals, sunshine, and opportunities for water to drain have been ample across Sarasota, Manatee, Hardee, and DeSoto counties. Thus, the current Flood Watch through this evening looks to be good at this time. Trends will be monitored over the next few hours. Over the next couple days, a transition will take place as the trough axis is replaced by an upper-level ridge. As this happens, winds will shift from a WSW to eventually an ESE pattern, with more typical diurnal convection settling in for at least a few days. Some drier air could even make this convection more isolated in nature, at least initially. Overall, though, more typical summertime conditions return and last into next week.

&& .AVIATION... (18Z TAFS) Issued at 137 PM EDT Thu Jun 13 2024 Showers and thunderstorms continue to impact SWFL terminals this afternoon. The expectation is for a lull in activity across the region for a few hours before storms reform towards morning. Simultaneously, diurnal convection across central Florida is expected to develop this afternoon/evening, albeit later than normal. This looks to be a short-lived window before also quieting overnight. One more day of significant thunderstorm impacts is forecast, before a return to more typical diurnal impacts over the weekend and into early next week. && .MARINE...

Issued at 309 PM EDT Thu Jun 13 2024 Scattered to numerous showers and thunderstorms continue to be possible at nearly anytime across coastal waters, especially in SWFL. A more typical summertime pattern sets up over the weekend and continues into next week as winds shift from WSW to ESE. While hazardous waves and seas will remain possible in the vicinity of storms, light winds and seas are expected away from any storms.
