Well to clarify, when you say cold suppressing.... it is other features on the map actually. I am not sure anyone here or in any thread fully understands it but in the case the low (bowling ball) coming from the west is in bullying its way to relevance longer which in turn brings more of a SE flow and moisture tap into much more of PA instead of it giving up to the coastal earlier. It is still being blocked from cutting to our west but something changed to allow it to go quite a bit further East than progged just 24-48 hours ago. Some models like the UK foretold of this possibility.
I did not believe it and it still may be folly but cannot ignore it at this point.
