Boston AFD...
Overview...
Explosive cyclogenesis occurs off the Mid Atlc coast tonight, with
an impressive ~40 mb pressure drop in 24 hrs, yielding a bomb
cyclone of around a 965 mb low over the eastern MA waters Sat
evening! 00z guidance trended west and is in somewhat better
agreement than previous runs, however differences still exist. The
00z NAM (especially the 12km NAM) the deepest, slowest and farthest
west solution of the 00z guidance. Therefore followed a non NAM
model blend solution for this portion of the forecast.
