All of our medium and short range models indicate a storm system will move into Maryland by Friday afternoon and linger into Friday night. As arctic air settles across the state this week a storm will develop along the boundary of very cold air to the north and "milder" air to the south producing enough lift to create snow and rain across the region.
Below is the GFS (Global Forecast model) around Friday 1pm. The rain snow line is situated just south of Baltimore city with sleet over Washington DC. This model has been consistent in the rain snow being just south of Baltimore. Cold air aloft will be dragged down to the surface allowing for the entire column of air to be flooded with COLD. This means snow will be dominate with some sleet from time to time.
Thanks for the update Mike! Great to see you on Channel 2 in Baltimore.
Quick question. How come every weather station in Baltimore 13, 11 and 2 seem to forget about Cecil County up in the Northeast corner of the state? I don't know whether to use Baltimores forecast or Phillys :) Maybe I'll just take the average of the two and call it good!
