...THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL ACROSS PORTIONS
OF NORTHERN FLORIDA AND SOUTHERN GEORGIA...
...21Z Outlook Update...
A convective complex should be ongoing across southeastern
Louisiana and adjacent north-central Gulf waters at the beginning
of the forecast period. This complex will migrate eastward toward
the Florida Panhandle and vicinity throughout the morning hours,
although heavier rainfall should remain offshore due to a lack of
inland instability. Light/modest rain rates are expected across
most of the Southeastern U.S. downstream of the complex, and models
have trended lower with QPF especially through northeastern
Florida.
Given the latest trends, the Marginal Risk previously in effect has
been confined to areas from southeastern Louisiana through the western
Florida Panhandle closer to where the best instability should
reside.
See the previous discussion for more information.

...Previous Discussion...
Surface low developing along the central Gulf Coast on Day 2 will
continue to track east early in the period, before tracking
northeast along the Southeast Coast later in the day. Training
storms, with potentially heavy rainfall rates fueled by deep
moisture (PWs 1.5-1.75 inches) ahead of the wave and along its
trailing cold front, may produce locally heavy amounts and an
isolated flash flooding threat on Wednesday.
