.DISCUSSION...

Overnight...Moisture gradient continues across area with higher
values to the north. Onshore flow supporting few showers moving into
Volusia county but most significant activity over JAX forecast area.
Short range meso models indicate additional showers may move into
Volusia and even northern Brevard county overnight as measure of
decoupling begins and frictional convergence is enhanced. Current
forecast depicts this well with only minor changes expected.
Forecast temps on track.
