Here's a radar loop. You can see the system offshore.

This would be the time to start looking at surface observations (METARS, ship reports, buoys, C-mans)
(One of the mods can thumbnail these if desired)

Here are some points I would consider: If a LLC were to form it would be brief and TINY based on the current observations. Given the quick forward speed (enviromental H85 to H50 flow is about 25-30KT), 15-20KT S-SE surface flow ahead of this system, this feature only has about 6 more hours to generate enough surface pressure falls to reverse the flow ahead of it to a northerly component before it moves inland over NC.
Consider that the environmental flow is also gettting squeezed between the stout deep layer western ATLC ridge and an approaching short wave trough.
It's a race against time, and I think the system will make it to the NC coast before having the chance to close off.

SPECIAL TROPICAL DISTURBANCE STATEMENT
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
228 PM EDT TUE JUN 27 2006
RECENT INFORMATION FROM AN AIR FORCE RESERVE RECONNAISSANCE AIRCRAFT
INDICATES THE AREA OF DISTURBED WEATHER IS CENTERED ABOUT 35 MILES
SOUTHWEST OF CAPE LOOKOUT NORTH CAROLINA. WHILE THERE IS A SMALL
AREA OF GALE FORCE WINDS ON ITS EAST SIDE... THE SYSTEM DOES NOT
HAVE A CLOSED SURFACE CIRCULATION... AND IS THEREFORE NOT A
TROPICAL CYCLONE AT THIS TIME. THE AIRCRAFT WILL CONTINUE TO
INVESTIGATE THE SYSTEM THIS AFTERNOON.
THERE IS STILL THE POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A
TROPICAL STORM AS IT MOVES NORTH TO NORTH-NORTHEASTWARD AT 20 TO 25
MPH. RESIDENTS IN COASTAL REGIONS OF NORTH CAROLINA... VIRGINIA...
AND THE DELMARVA PENINSULA SHOULD CLOSELY MONITOR THE PROGRESS OF
THIS SYSTEM TODAY AS TROPICAL STORM WARNINGS COULD BE REQUIRED WITH
LITTLE NOTICE. EVEN IF THIS SYSTEM DOES NOT FORM INTO A TROPICAL
CYCLONE... IT WILL PRODUCE SHOWERS AND THUNDERSTORMS WITH LOCALLY
HEAVY RAINFALL AND STRONG GUSTY WINDS ACROSS THE MID-ATLANTIC AREA
TODAY AND TONIGHT.
