We just need to have the remaining winter cold dissipate. What we have is a warm Canada, polar jet evaporated and we are left with the stagnant leftovers (ie blocked pattern). Once it dissolves to nothing we can resume warmth.
Hitting mid 80s here in southern Wisconsin. This pattern isn’t actually that far off from what we had in March “Morch” 2012. This is not a one day warm up then back down — we have sustaining. I saw the signs of a week of this back when I said we would have a Morch. Delayed but not denied.
