Should be a fun day tomorrow in the low country.
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
This Evening: Latest EMC RAP analysis from SPC shows PWATS of
at least 2.25 inches pooling across Southeast GA bands of
convective rains persist, resulting in periods of heavy rains
with pockets of torrential downpours ongoing along the lower
Savannah River region of the forecast area. We will continue the
Flash Flood Watch in place on this update package.
Overnight, parameters are coming together for additional heavy
rainfall further up the coast as low pressure organizes along
the stalled front and propagates to the northeast. Strong moisture
convergence ahead of the low in the vicinity of the front coupled
with high PWATS and lingering nocturnal instability will support
a corridor of moderate to heavy rainfall extending from the
Georgia coast north into the Charleston Metro Area, including
Savannah and Beaufort. High resolution guidance are similar in
showing the heaviest rains falling in the Savannah to Charleston
corridor with general rainfall amounts of 2-5 inches with some
members showing amounts in excess of 6 inches. Although flash
flood guidance values are still somewhat high and D1-D2 drought
conditions linger, the high PWATS within a weak steering flow
environment suggest the resulting convection will be efficient
in rain production which could overtake the 1-hr and 3-hr flash
flood guidance values.
I have a feeling since we have escaped rain for the most part the last 3 day in mt pleasant that we could get hammered tomorrow.
