So do we need the Alaskan disturbance to catch up with the developing coastal and capture it to bring it westward and bomb out over the midAtlantic? Is this what the writeup was referring to?
You want a BIG snowstorm, you can't have the primary coming up the Appalachians. Our BIG ones form in the Gulf of America and then reform around HATTERAS and move N or NE up the coast. We'll be lucky to get 8 inches in the metro area with this one.
You'll never change. Calm down. This is an easy one. The cold is locked in. The storm is coming in from the SW and the HP will retreat to the north allowing the coastal LP to bomb out, maybe.
