Issued at 252 PM EDT Tue May 12 2026 A frontal boundary is pushing through the state. As it does so we are see some stronger cell developing along the boundary. We can expect these storms to continue to track inland throughout the afternoon hours with most areas dry by the last evening hours. Some high res models redevelop showers along the coast in West Central Florida overnight but not expecting any strong storms. By Wednesday morning the front should be draped over I-4 and continue to push south. With the front still lingering we will see the instability and moisture still around the area. The westerly flow, however, will keep most of the shower and storm activity to the interior and eastern half of the state. As we get into Thursday and Friday drier air will start to filter in stopping any shower activity from forming. RHs will also be dropping in the mid 30`s by Friday. The moisture will slowly start to increase mainly in south Florida during the weekend.This will bring some isolated afternoon showers back into the forecast. However, the bigger story for the weekend will be the heat with highs topping out in the low to mid 90`s away from the coast. By next Monday moisture will continue to rise and the flow shifting more easterly. This will be better news for our coastal communities as evening storms should push off the west coast. && .AVIATION...
