The winter storm's central pressure continues to rapidly drop this evening, now near 980-981 millibars. Pressure is 982 millibars in Millersburg, WV and Johnstown, PA is currently 983 millibars. The radar overlay shows the storms lining up perfectly along the cold front, which is also clearly visible in the isobar kinks extending down the eastern side of the Appalachians. This is a storm right out of a meteorology textbook.
