Psyber, what is keeping it out to sea is the front that just passed through the eastern US yesterday, The high pressure behind it is pushing Arthur east, allowing Arthur to track along and just east of the front itself.

You can see the track that Arthur wants to take by looking at the mean layer wind analysis from CMISS: http://tropic.ssec.wisc.edu/real-time/dl...zoom=&time=

You can also see the remnants of the front over PA, NY, and New England that marks a line just in front of the high pressure that is helping keep Arthur off shore: http://radar.weather.gov/Conus/full_loop.php

I have 20mph winds with gusts to 30mph where I am from the front itself; I am too far from Arthur and on the other side of the front for Arthur to be the influence for my winds.
