SUNDAY - The peak of our stormy pattern will arrive this weekend coincident with a AO/-PNA spike. If April was a seminar, the Sunday storm would be the keynote speaker. Not to understate the impact of our current system; it's certainly been interesting. It appears the week leading up to a spike are more active than the week immediately following it. Next week northwest flow
interrupts our active pattern bringing seasonably cool temperatures. Wisconsin has been on the cool side of the current system and should be on the cool side this weekend. The occlusion of the Sunday storm could block us out of meaningful t-storm threat. I was wondering if this signature system would bring a severe weather event to Wisconsin but just doesn't look like conditions are in place yet though that could still change.
