I've noticed for a few weeks the cold SST anomaly hugging the east coast
of the USA (-2 ~ -2.5°c) together with the warm strip to it's south
(+2°c), quite a gradient in SST's.

I've always been a bit suspicious of that site. It often shows quite
large negative anomalies not reflected elsewhere
(http://lwf.ncdc.noaa.gov/img/climate...t.20061108.gif
for example) and some fairly wild fluctuations.

There have been persistent offshore winds in that area, which in fact
is fairly normal, and does cause upwelling of cold water near the
coast.

More interesting for early next week is
