The GFS is doing its normal run to run disco from Jan. 30 - Feb 5.
Regarding a possible late winter pattern, the Euro Weeklies more or less paint a January thaw beginning early week and extending thru Feb 5. Could be mild and wet. A developing plus PNA encourages eastern troughiness and lower heights from Feb. 15 - March 5. If that verifies, late Feb. into March could be quite interesting.
Experts, please tell me why this wouldn't work.
