.PREV DISCUSSION... /ISSUED 1121 AM CDT Wed Oct 02 2024/

...Synopsis...
Latest visible satellite imagery and surface observations indicate a
quasi-stationary surface boundary extending across portions of
northern FL. South of the boundary, diurnal heating of a moist air
mass, coupled with sea breeze circulations, will support scattered
diurnal thunderstorm development. Deep tropospheric moisture and
steepening low-level lapse rates may support a few wet microbursts
with strong-gust potential over central FL -- where any localized
clustering occurs. However, weak deep-layer shear and poor midlevel
lapse rates should limit the organization and intensity of storms.
