Possible Significant East Coast Storm Next Friday

Related Articles

Good afternoon, confidence is starting to increase in a potential significant northeast storm next Friday.  A strong high pressure system over Greenland will develop over the next couple of days causing the pattern to slow down and not be progressive.  A low will then develop over the Midwestern states tracking towards the East Coast.  Guidance is currently in disagreement on the evolution of the low making it’s exact track low confidence at this time.  The GFS is the most northern solution with a low that transfers from the Great Lakes to off the NJ coast which sits there and stalls producing gale force winds.  The European is the more southern solution that like the GFS transfers the low right off the NJ coast producing powerful winds.  Details like precipitation types and snowfall amounts can not be ruled out till Monday, but at this time I would favor a rain to snow type solution.  Guidance will continue to change every run due to the complexity of the setup and the energy still over the Pacific.  Just know that this system has the potential to be a very powerful one especially when we have a Greenland blocking high which tends to slow systems down and stall them out.  I will update again either tonight or tomorrow when I analyze the new guidance/data
