Taking another look at teleconnections, PNA
and AO. It has been rather unsettled lately. It's been warm but not record breaking warm like it was in February. Interesting. The PNA
has been gradually decreasing since late March and storminess has increased in response. Low pressure systems have been interesting and healthy. April the last few years has yielded almost nothing, nice change. Looking at the AO (see picture) it's easy to see a pattern. So I'm wondering if early May will bring a significant storm pattern?
