.DISCUSSION...
A broad area of high pressure will continue to keep conditions over
the waters relatively benign for a few more days. Winds will be
light at 10 knots or less and seas will remain below 2 feet. The
seabreeze cycle will lead to some variability in wind direction near
the coast, and a few thunderstorms could fire up in relation to this
seabreeze/landbreeze cycle. Any storms will be short-lived and will
produce locally gusty winds and lightning. A weak backdoor cold
front is still expected to slip into the waters Tuesday night into
Wednesday. Winds will become more chaotic as it stalls over the
waters but east of the MS Delta winds will briefly turn
northeasterly and increase to 15 knots possibly even approaching
20 knots. Thunderstorm activity will be a bit more widespread as the
front moves through, and a few stronger storms with high wind gusts
could develop. By Thursday the front will washout and as a large
area of high pressure becomes established over the southern
Appalachians moderate onshore flow will return.
