Everyone seems to be focused on the Sunday/Monday event. I however would like to mention that the models are showing a better and better with each run developing system behind the Sun/Mon Bringing another round of decent snow to i70 norh in IN/OH again and as well into Michigan and Central PA on into the NE. Heaviest right now looks to be in Michigan *especially areas closer to Detroit* Northern OH, NW.PA, into NY and on into the rest of the NE especially towards Boston. All i can say is wow.
BTW this is mostly based on the 12zGFS. Has been showing on other runs as well but a bit back and forth with it. Todays was most impressive so i figured i should mention it. Keep a eye on it ESPECIALLY those that may miss the first system.
total precip for second system. Note that areas from about Philly on south some of this does include the Sunday/Monday system.
*Edit*.......Look at my reply below concerning the 18z GFS!
