The SER is part of the base state we are dealing with this winter. It is a function of the La Nina and fits Nina climo. The key is cashing in when there are windows when it gets squashed or acting as a flat ridge / gradient. It was a certainty the SER would pump at times this season.
Eta: so with that said, step back from the ledge. Winter is not canceled, winter is not over. We've been frozen, give or take a couple days, since late November. Consider the relax in the pattern our annual January thaw. Seems like a pretty average winter thus far, no complaints.
