18z GEFS through Day 13. Not there yet, but this is edging towards greatness just slide that ridge a nad or two further east. You can see the potential. This fits right with my thinking of seeing a ridge/cold pattern by mid-December. C'MON! Ya gotta believe!!!!

That last system way out west near the dateline ~180 W is undergoing rapid cyclogenesis. The 18z NWS/NCEP Pacific Surface Analysis forecasts this low to deepen from 980mb to 957mb.

12z GEFS, CMCE, EPS - Moses Lake. Surface temps. Long range very good agreement for cold pool development.

Oh my gosh how horrible. Absolutely terrible. Very sorry to hear this! You will all be in my thoughts.
