Pattern January Joke

With it being pretty quiet in here, I think this is a good time to remind folks of the significant warm biases of the ens means over the last 90 days (180 EPS runs/360 GEFS runs) over the SE: keep in mind that these go back to late Sept/Oct meaning they’d be larger if we were just looking at the higher volatility Dec. Note also the cold bias in the NW US/SW Canada, which combined with the E US warm bias is indicative of a notable -PNA bias.

11-15 EPS: 2-4F

11-15 GEFS: 2-4.5F

The bias starts with day 1, but grows with forecast time. Thus the 6-10 also has been warm biased but not by as much as the 11-15:

6-10 EPS: 1.0-2.5F

Interesting analogs centered around mid January.
