Dense Fog Advisory issued January 20 at 11:05PM EST expiring January 21 at 8:00AM EST in effect for: Adams, Clearfield, Cumberland, Dauphin, Elk, Lancaster, Lebanon, McKean, Perry, Schuylkill, Warren, York
Here it comes ! A winter storm storm watch and warning has been activated across the state. What this means is a snowstorm capable of producing significant snow is expected.
Right now our storm is in two pieces, one situated over the central Plains while another one is developing over the Tennessee Valley. I expected these two pieces to phase together producing a brand new low that will become intense rather quickly. Snow will then enhance pushing in from south west to north east.
