Based on the last two weeks of incessant model posts of things 240+ hours away my thoughts have been this
12/5-12/10: pattern starts changing from mild to seasonal or BN
12/12-12/17: storm chances increase, too early to know precip type
12/20-12/31: pattern stable or RELOAD?
If I’m wrong someone let me know. If it wants to snow after the -AO/NAO sets in then great but D+7 models won’t know until mid month
