January so far was very cold than very warm at times very snowy and very rainy. Extremes is the best word I can describe. Next week looks to be interesting for a potential coastal low developing and with it bringing a general 3-6 inches for Philadelphia and NYC. Most models have been hinting it. I think after Tuesdays rainstorm the pattern changes digging the jet stream just enough to develop a low off the coast of Cape Hatteras, NC and tracking northeast. It will be marginally cold so if it does snow it'll be a heavy heavy wet snow. Most global models like GFS, EURO, GGEM and even CMC are suggesting this idea. From personal experience I think from a changing pattern you could get dynamic storms off the coast and since the ocean temps are in the upper 30's it will be mostly a snow event even if it does start as some light rain that should turn quickly into heavy snow as the cold air rushes in from the north. In fact the storm should be dynamic enough to make it's own cold air. Also I want to point out that megalopolis should do well with a general 3-6 inches of snow I think the suburbs will get more because it's just colder there and it'll be below freezing while the event happens. Washington, D.C. May only get a couple of inches. Let me hear your thoughts on this event?

Yea I hope so too. This will most likely trend to a bigger dynamic storm because NAO being negative meaning there will be blocking across Greenland, therefore that usually slows the storm down and pna being positive usually develops a trough which could quickly make a bombogenesis off the coast off. Cape hatteras. Also gfs lost the storm last night but brought it back today at the 12z run. I'll update the euro 12z run but in my opinion we are headed to a big snowstorm. It'll catch a lot of weathermen/weather women off guard.
