Im basically doing a signal versus noise calculation. It looks like an interesting study, and it relates to last month's blog post on the discrepancy between observed and modeled Pacific sea surface temperature trends. On average across the UK, there are only 15.6 days a year when snow is on the ground, though this rises to 26.2 days for Scotland alone. They have literature on Modoki La Ninas. The data shows that the La Nina jet stream pattern also changes the snowfall patterns over North America as the pressure systems take a different path, along with the cold air. Regarding the "warm blobs" you mention, most studies suggest that extratropical sea surface temperature anomalies generally do not have a major impact on the large-scale atmospheric circulation, so I suspect that the two warm blobs you mention did not have a major impact on Southwest U.S. precipitation. These are blog posts, not official agency communications; if you quote from these posts or from the comments section, you should attribute the quoted material to the blogger or commenter, not to NOAA, CPC, or Climate.gov.
