The North Pacific jet stream continues to scream along zonally from Japan to California with only some wave breaking evident as major extratropical cyclones rapidly intensifying on the poleward side.

Warmth and moisture from the subtropics is pushed eastward into western North America fueling the persistence of a blocking ridge. Until this pattern breaks down, we will continue to see abnormal early winter warmth and much-above normal temperatures across the Lower 48. Not seeing the pattern flip for the next 10 to 14 days at least, but that doesn’t mean the models can’t throw a curve ball into 2025.
