We have a decaying frontal boundary off the coast. Look about 250 miles or so south of Hatteras and theres an area of convection there.
Theres some upper divergence over this(weak high). Shear is in the order of about 10 knots and theres a high getting established over New England.
This is nothing to get too excited about but this is close to the coast and conditions could favor subtropical/hybrid development.

You can always trust the CMC to give you something 
Very time sensitive, mid level twist off SC, http://radar.weather.gov/radar.php?rid=LTX&product=NCR&overlay=11111111&loop=yes I don't know how to save off long range loops as gif, and the weather underground only has short range.

Off SC/NC coast.
Was watching the tale end of this front the last couple days and late last night and now this morning we have a low off the SC coast.
latest obs in the area and satellite show that we have a closed low and convection is becoming more concentrated this morning near the center. about 31.4N 78.9W. pressures are pretty high but are slowly falling and there are winds gusting to about 35mph this morning as well.
Development of this system could occur as for the moment it is relatively stationary and should be for the next 12 to 24 hours before a slow NE to NNE drift should occur after which if its still over water a ridge is expected to build in and could keep the system around a little longer.
upper winds seem favorable as right now its sitting in a upper ridge, the real strong winds are a little farther north that it is right now.
so its a area to watch.

Re: Off SC/NC coast.
This thread should be getting a lot more play. Homebrew is gonna be where it's at for this season. and Gulf Stream/NC/SC homebrew rapid spin-up is absolute classic stuff.

Re: Off SC/NC coast.
There is indication of two spins on radar, with the one at the surface seeming to correspond to the surface low as indicated by quickscat. Looks to be over the Gulf Stream, too, and in a favorable (albeit narrow) area of upper level winds.

By the middle of the week this feature will be gone from the EC.

Re: EAST COAST DEVELOPMENT MIDDLE OF WEEK
This is NHC's take on it:
ABNT20 KNHC 061745
TWOAT
TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
200 PM EDT SUN SEP 6 2009
FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...
A BROAD AREA OF LOW PRESSURE LOCATED JUST OFFSHORE OF THE COAST OF
SOUTH CAROLINA IS PRODUCING DISORGANIZED SHOWERS AND THUNDERSTORMS.
UPPER-LEVEL WINDS ARE NOT CONDUCIVE FOR TROPICAL CYCLONE FORMATION
AS THIS SYSTEM MOVES SLOWLY NORTH-NORTHEASTWARD. THERE IS A LOW
CHANCE...LESS THAN 30 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS....

The steering currents are really weak right now, so it could hang around longer than you might think. From LWX this morning
http://forecast.weather.gov/product.php?site=NWS&issuedby=LWX&product=AFD&format=CI&version=1&glossary=1&highlight=off
ONE THING THAT CAUGHT MY EYE IS THE VORTEX WELL E OF GA/SC...AND
HOW MODELS HANDLE IT IN THE COMING DAYS. UPR WIND FIELD IN THE WRN
ATLC IS WEAK...AND THAT LOW LOOKS TO SLOWLY MEANDER CLOSER TO THE
VA CST BY TUE/WED. AT SAME TIME SFC HIGH OVR NEW ENGLAND MIGRATES
TO A POSN WELL E OF ME...SO IT APPEARS AN ERLY FETCH WL BE
SETTING UP IN MID ATLC. SO HV INCRSD THE CLD CVR FOR MUCH OF THE
WK AHD...AND IT MAY TURN OUT THAT LATER SHIFTS HV TO INCRS IT UP
TOWARD OVC FOR MON NGT-WED.
