.SYNOPSIS...

A cold front will cross our local waters late this afternoon and
early this evening, accompanied by showers and a few embedded 
thunderstorms. Winds will shift to northerly later this evening 
as strong high pressure builds eastward towards the Ohio and 
Tennessee Valleys. Northerly winds will then strengthen overnight,  
resulting in Small Craft Advisory conditions developing throughout
our local waters during the predawn hours. Strong high pressure 
will then progress eastward towards the Mid-Atlantic coast by 
Friday evening, with this feature briefly wedging down the 
southeastern seaboard on Friday, creating strong northeasterly 
winds that will continue into the early evening hours, with 
occasional gusts to Gale Force possible offshore. Winds will shift 
to easterly during the overnight hours and then southeasterly by 
Saturday morning as high pressure shifts off the Mid-Atlantic 
coast. This weather pattern will allow a warm front to lift 
northward from the Florida peninsula, with showers developing on 
Saturday and Saturday evening as this boundary lifts northward. 
Elevated seas will keep Small Craft Advisory conditions in place 
offshore this weekend, while Advisory level seas near shore 
continue through Saturday afternoon.

Meanwhile, low pressure developing over the lower Mississippi
Valley on Saturday afternoon will strengthen as it accelerates
northeastward across the Tennessee Valley and the southern 
Appalachians, with this storm system's cold front approaching our
local waters on Sunday afternoon. Southerly winds will gradually
strengthen on Saturday night and will shift to southwesterly on
Sunday, with Small Craft Advisory conditions redeveloping near
shore. Showers and a few embedded thunderstorms will cross our
area on Sunday afternoon and evening, followed by winds shifting
to northwesterly in the wake of the frontal passage before
midnight. Arctic high pressure will then spill into the Plains
states early next week, with strong northerly winds keeping Small
Craft Advisory conditions in place for the offshore waters through
at least Monday afternoon.
