DISCUSSION: Winter Storm Grayson has been pummeling the eastern seaboard of the United States these past few days with blizzard conditions, arctic cold temperatures, and storm surge. There is an enormous amount of detail surrounding Grayson, so let’s start with the formation:
Grayson started off as a winter storm January 2nd. From there, it rapidly transitioned into a Nor’Easter through a process meteorologists call bombogenesis. Bombogenesis, also known as explosive cyclogenesis, refers to a pressure drop of 24 millibars in 24 hours. This storm dropped 59 millibars in 24 hours, generating huge amounts of wind and energy. The reason this storm is so unprecedented is that we rarely see bombogenesis this extreme.
Grayson has left historical impacts all along the east coast. Some of them being: Savannah, Georgia and Charleston, South Carolina breaking one-day snowfall records, it produced the first measurable snow in Tallahassee, Florida, in over 28 years, wind gusts in excess of 70 mph were reported in the Outer Banks of North Carolina, white out conditions and heavy snowfall in New York City and the tristate area, and finally Storm surge, high winds, and blizzard conditions in New England.
Perhaps the most destructive part of this storm is occurring in New England, where bone chilling temperatures, combined with storm surge, flooding, high winds, low visibility, and heavy snow are halting life. The high winds and flooding is bringing ice shards into the streets making it difficult for the National Guard to help residents. Power outages are also a major concern and a race against time for the National Guard. Evacuations are underway in the areas most affected by this storm. The following days after Grayson will bring temperatures unheard of in the past 100 years to the Eastern United States.
Grayson will absolutely go down in the record books as one of the most intense winter storms the U.S has seen in a very long time. For more information on winter storms, be sure to click here!
