As we head into mid December the pattern is shifting. After the weeks of warmth up in Alaska and cold across much of the Lower 48, we about to see a switch with +AO/NAO.
The big flip comes this weekend into next week as heights crash over AK/N Pacific while Pacific winds begin to sweep milder ocean air across the country. We could see the first -50F with this colder pattern returning to AK.
Note the shift in 5-day means between 1-5 and 8-14 day period.
