Snowfan rreports here of how parts of western Germany have had 4 nights in a row of surface frost and how new models are even projecting snowfall already in mid October. If that occurred, it would be unusually early.
Globe cooling off
Overall the globe has cooled substantially since the last El Nino ended in 2016, and it now appears the cooling trend will persist another year as the CFSv2 is forecasting a La Niña to continue into spring 2022.
The latest NOAA/CFSv2 projection dated September 23, 2021, indicates La Niña-conditions over the Nino-region 3.4 of the equatorial Pacific.
NOAA forecast from September 13, 2022.
