The link below from the Aussies has a good database of historical MJO values. It appears that we do poorly when in a lousy state like high 4/5 etc., but many epic stretches have occurred when we are dicking around the COD...for instance February 2015.

Edit: February 94 was high 4/5
It's gonna be tough with the MJO progged to go into a high 4/5. Maybe things improve towards the last week in January. Was it 2007 or 2008 when we went from a mild January to a very cold and sleet-filled February?
That band running from Watertown NY to New London does not seem to be concentric with the storm. I think it's a very long Norlun. Lookout for some weird ****e tonight.
