The average of the last 12 CFSv2 weather model runs for December looks strikingly similar to the analogue below using the average of the 5 most similar previous years sea surface temps across the Atlantic & Pacific oceans.

1: Find top 5 most similar NH sea surface temp patterns to now. 2: Look ahead to Dec in those years & take average mean sea level pressure. 3: Europe =warm mainland, wet/windy N, dry S. 4: Just interested if this simple method points us in right direction (via @WorldClimateSvc)

A big low pressure anomaly will impact NW Europe this week, bringing some wet & windy weather with well above average temperatures. I'm expecting the GB wind power record to be broken on Wednesday.

Couldn’t wait to see this afternoon’s NASA satellite photo. And what a stunner!

NASA satellite imagery shows interesting cloud patterns, notably across Scotland & Ireland, caused by lee waves.

After a very mild first half to November, much colder air will become established across Europe during the second part of the month.

The sub-surface temperature anomalies show warm anomalies have increased significantly. A large pool of warmer than average water extends across the sub-surface of the equatorial Pacific, between ~150°E to ~100°W. Parts of this region are >3C warmer than average (via @BOM_au)

Expected weather patterns indicate temperatures will be above or well above average across large parts of Europe next week. This means heating demands will be lower than normal across many countries. (High confidence).
