We are looking at quite a stormy end to the month of November with the famous ” Greenland Block ” on the horizon. Higher than normal 500mb heights are showing up around the Greenland region which helps slow down the overall pattern across the lower 48.
First off we will have a clipper system that dives in across the Great Lakes to set the stage for a potential larger system behind this one. This will bring some snowy showers across the Lakes and rain for much of the Mid-Atlantic and Interior Northeast.
Between the 24th-29th, Models have been hinting at a more robust storm system to enter in across the Ohio Valley with a stronger block established south of Greenland. In correlation with the latest NAO teleconnection forecasts, It makes good sense with a fairly negative signal showing that blocking pattern quite well near Greenland. Make sure to keep in touch with the latest forecast for potential travel delays during the Thanksgiving Holiday.
