.DISCUSSION...
A cold front will track through the region early this morning
before stalling to the south near the Virginia/North Carolina
border. This frontal system remains south of the area through
mid-week. Persistent easterly onshore flow will lead to cloudy and
cool conditions along with the potential for showers. By Thursday,
this front eventually pushes away to the south and east as a cold
front. Weak high pressure returns over the region by late in the
week into the weekend.
