While snow is what we all look at, the first flakes are a mere spectacle compared with the potential coastal impact.<br>&nbsp; The weather pattern has been conducive to deep troughs in the east. My gut feeling is that we see the track shift north and west as time goes on. The <a href="http://www.cpc.ncep.noaa.gov/products/precip/CWlink/pna/nao.shtml">NAO is positive</a>, that usually means we have storm track inside the benchmark (40^N, 70^W). Most of the storm this fall have been inside runners.<br>&nbsp; If this one egos inland, then the snow shifts west and the wind at the coast is stronger and more perpendicular to the shore line.<br>&nbsp; The high tide is at Noonish Thursday, Midnightish Thurs Night, and just after lunch Friday.<br>&nbsp; A Mutli-Day storm is possible, as we are tracking several waves of low pressure. A weak low Monday Night, then a stronger one later Weds. Then another one or two waves Thursday and Friday. The weather models have a hard time focusing on which wave will be the strongest. Our forecast will become clear as we close in.<br>&nbsp; <a href="http://water.weather.gov/ahps2/hydrograph.php?wfo=box&amp;gage=bhbm3">Here is much more information on The Potential Coastal Flood Threat near Boston</a>.
