The blocking pattern we’re in now is usually a pre-cursor to a major, slow-moving storm along the eastern seaboard. It should be no surprise to those who read here as to why this could happen; but now the possibility is growing even larger as model guidance is starting to converge on the general theme of the intense storm, with the details of the actual track still to be worked out in full.
TIMEFRAME: Wednesday through a large portion of Thursday
STORM SCENARIOS:
In terms of precipitation, prospects for an all-snow event for NYC and the coast are low, but even residents there could still end up with a heavy accumulation at the end of the storm, with at least half of the event being rain. Inland areas stand to get the most snowfall, with the highest (right now) potential for a disruptive snowstorm south and west of Interstate 95.
for the coast, the unfortunate scenario of a siege on the very fragile coastal sections of New Jersey and New York is a very real possibility (even with a more off-shore track), as the painfully slow-moving storm would pile water into our shorelines for 1-2 days! The saving grace is that the astronomical tide cycle is low, which will mitigate (somewhat) the affects of coastal flooding and beach erosion.
More later.
