The GFS model continues to be very consistent of the development of a tropical system that comes up the East coast and potentially gets wrapped into the jet stream to produce a major storm. The CMC is going along with the GFS idea while the ECMWF is out in left field. The NAO is going to go more toward neutral while the PNA is going to positive which to me indicates that colder air will get involved with any storm that does develop. How the blocking pattern plays into the storm remains to be seen, but if a neutral pattern develops, we are talking more about a storm zipping up the coast and not really getting wrapped in. In any case, the crazy tropical season may bring at least one or two more storms, one of which could impact the U.S. coast.
