Plummeting Water Temps Spell Trouble

The recent cold spell has dropped the surface water temperatures big time.  Last week temps were running in the low to mid fifties.  Today I checked a NOAA site, http://tidesandcurrents.noaa.gov/ports/textscreen.shtml?port=nb

Dropping water temperatures and rough water have made
scenes like this a memory in the past.  It has been a tough
last couple of days with little to report.

and the water temperature along the ocean (Newport) was 48 degrees.  Parts of the Bay were 46 to 48 degrees. Those are big drops, certainly enough to send the fish packing. In addition, the oceanfront has remained rough since Monday's big blow. My source along there reports little fishing activity, no bird activity and no fish that he knows of. 
Is it all done?  I just don't know.  There will be a recovery in temperatures next week.  Will it come too late?  I suspect there will still be a few fish coming through in the next week or so, but you will have to be there when it happens. The consistent fishing could be over.
Unless I hear of something along the oceanfront, my plans are to start searching the winter locations that I fish.  I'm guessing that will start up very soon if  it hasn't already.
