.DISCUSSION...
KEY MESSAGE 1: Prevailing high pressure will yield minimal rain chances through mid-week with above normal temperatures.
Zonal flow/broad ridging aloft will dominate across the southeastern states early this week, with surface high pressure holding strong. This set up will favor a warming temperature trend, with high temperatures in the low to mid 80s by mid-week. Given plentiful dry air and very little model support, PoPs have been lowered Tuesday afternoon to only slight chance across inland locations. While a weak shower is possible Wednesday afternoon, the chances of meaningful rainfall are very low.
A cold front will approach the region late in the week, a higher potential for measurable rainfall this weekend.

Small Craft Advisories for the nearshore SC waters (out to 20 nm) will end shortly after midnight as a result of seas dropping below 6 ft.
