12 UTC upper-air sounding out of KTBW sampled a distinct dry layer between 500mb-725mb, allowing for isolated low-topped shower development across the area this morning. In contrast and not surprisingly, this layer does not exist at KEY/MFL and higher PWs are present. This pocket of deeper moisture will continue to advect north due to persistent southeast flow in response to the surface low developing in the Gulf. RAP Forecast soundings show our mid- level dry slot all but gone by noon time around TPA. Expect the rest of Thursday to be cloudy with a good chance of rain through most of the day. Temperatures are expected to be in the low 80s south to mid 70s north, although exact timing/duration of rain will lead to some variability in temps for some folks. Current forecast remains on track.
