.SYNOPSIS...
A tight pressure gradient between a series of lows over the 
Southern Plains and a surface high off the east coast will allow 
for a prolonged period of strong and gusty southerly winds. 
Sustained winds are likely to be near or above 20 knots through 
the weekend with gusts over 30 knots. This, along with building 
seas to as high as 10 feet offshore, will bring about a long 
duration Small Craft Advisory conditions through the weekend. The
onshore winds will decrease early next week as the high weakens 
off the east coast and no deep surface lows are expected to form 
over the Southern Plains.
