Model forecasts valid through this week are trending warmer across the majority of the U.S. but colder across western Canada indicative of early stages of sustained La Niña forcing across North America. No model bodily displaces cold air south of the Canadian border through the next solid week due to large scale flow de-amplification already underway, but fast moving milder Pacific storms focusing primarily across the northern U.S. periodically tapping into modified cold air pooling north of the border favor less extreme temperature anomalies in both the East and West going into winter.  Less intense or prolonged cooling in the West, and greater temperature variability east of the Rockies (and precipitation) precludes repeat of widespread temperature records set during most of October and the 1^st full week of November. However, inherent to faster moving progressive flow is greater model uncertainty leading to diverging 11-15 day forecasts. GFS forecasts valid during the final 10-days of November are colder deep into the Midwest and East than European model forecasts. In this case a brief shot of noticeably colder air appears likely to reach the Eastern U.S. during the 11-15 day period as all models allude to varying degree of pattern re-amplification in late November. However similar to brief cooling this past weekend across the Great Lakes and Northeast featuring a one day shot of the coldest temperatures of the season (slightly below average) which quickly warmed back well  above average (60s), there is no indication of prolonged below average temperatures anywhere but the northwest quadrant of the U.S. through the initial half of December.
