Well, as the title explains snow is indeed on the way Monday Night and then again come Friday into the Night time hours.
I am as well as others becoming more confident that snow is going to visit many places in the Lehigh and Delaware Valley this upcoming week especially Friday.
Here is the 0z GFS for the more important Friday system still not sure the GFS has totally caught on to the pattern as there are still two lows evident. This could be signifying that the pattern we are going into may be too progressive but even so it would yield our most significant snowstorm in nearly 2 years in the Delaware Valley.
It looks like on this run the storm does not really get going until hitting the red x which would be a result of the neutral to slightly +NAO
Check out the video below I go into great detail about the Monday Night System and also the Friday System.
I also take a look at that percolating southern jet which is one of the keys to a large snowstorm down the road that can produce 12"+ for many parts of our area.
