Area Forecast Discussion
National Weather Service Jacksonville FL
851 AM EDT Tue May 30 2017

.UPDATE...High cloudiness will continue to stream over the
area. 12z soundings support model soundings suggesting potential
for scattered afternoon convection with sea breezes once temps
exceed 90 to erase low-level CINH. Updated hourly POP grids to
reflect an evolution with widely scattered cells over coastal
counties as sea breeze develops and starts moving inland...
with increasing POP values and coverage by 21z with greater
coverage inland portions of eastern counties...lower POP values
near coast. Decreasing coverage during the evening...but could
have some actvity continue `til Midnight. Soundings support
unstable conditions with surface CAPE 2500-3000 J/Kg with
fairly weak vertical shear...still could support a few intense
downdrafts leading to strong gusty winds with stronger cells.

High temp forecast today looks fine. Low level thickness
guidance suggests high temp values Today and Wed a few degrees
lower than past few days.
