Mid AM Zone Update: Impactful snow likely Friday
A few weeks ago we discussed the likelihood that winter would return in the early to middle part of the month of March. Well, here we are! High latitude blocking developed several days ago and is continuing to strengthen this week, moving westward from Greenland into Canada. This blocking is dislodging cold air, which otherwise would be bottled up in the Arctic region, further south.
As this occurs, a very notable temperature gradient will develop from the eastern Ohio Valley into the Northeast states. Forecast models agree that a disturbance in the atmosphere’s mid levels will shift through the aforementioned area from late Thursday Night into Friday, with a low pressure system developing along the thermal gradient and moving from the Mid Atlantic states off the coast to a position south of Long Island.
