I don't believe I ever started one of these storm threads but figured I would give it a go, the pattern is looking very favorable for several impulses to rotate around the Hudson's Bay low starting with the first one on Saturday/Sunday. This one could potentially need a thread of its own however because there is a potential of hooking into a bit of southern stream energy and a spinning up a decent system, see Sunday on the 12z and especially 18z GFS from today.
