Just look at this area of low pressure. 29.22 mb of pressure on the outer banks of North Carolina at Kill Devil Hills. That is pretty deep in weather man terms. Those lines around the low are called isobars, or lines of equal pressure. The closer the lines, the stronger the low. Close lines of equal pressure, also referred to as tightly packed isobars, translates into windy conditions. No wonder there are blizzard warnings out in and around the Baltimore/Washington DC vicinity.When this weekend is over, I think there will be numerous new snowfall records across the mid-Atlantic and coastal New England areas. Folks along the mountains of western Virginia, North Carolina, eastern Tennessee and West Virginia have already seen between 14 and 20 inches of snow.
I saw a report that said the record 2-day snow event for Washington D.C. is 12 inches dating back to the 1930s. For Baltimore it is 14 inches dating back to the 1960s. Both records could fall this weekend.
