SilverFallsAndrew Posted January 5, 2021 Report Share Posted January 5, 2021 We would be remiss September 2011 was (And still is.) the warmest September on record at SLE. I just did the math though, and even if their two warmest months, January and September had been exactly average, it would have still been slightly warmer than 2008, but cooler than the other years I mentioned. 1 Quote Snowfall Precip 2022-23: 95.0" 2022-23: 17.39" 2021-22: 52.6" 2021-22: 91.46" 2020-21: 12.0" 2020-21: 71.59" 2019-20: 23.5" 2019-20: 58.54" 2018-19: 63.5" 2018-19: 66.33" 2017-18: 30.3" 2017-18: 59.83" 2016-17: 49.2" 2016-17: 97.58" 2015-16: 11.75" 2015-16: 68.67" 2014-15: 3.5" 2013-14: 11.75" 2013-14: 62.30 2012-13: 16.75" 2012-13: 78.45 2011-12: 98.5" 2011-12: 92.67" It's always sunny at Winters Hill!

In his discussion, he shows Feb 2019 pattern as a result of Jan 2019 SSW, and Mar 2018 pattern as a result of Feb 2018 SSW. Oh, well those two were different animals altogether w/ different QBO background state for momentum deposition. So I don’t think you can compare them linearly like that. The Feb 2018 SSW was much better coupled to the tropospheric wave source(s) and had more constructive QBO for tropical connection. The Jan 2019 SSW, on the other hand, took awhile to downwell and biggest effects were indirect via the influence on the tropics. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Gradient Keeper Posted January 5, 2021 Report Share Posted January 5, 2021 00z GEFS Day 8-16. Ridge sets up sooner and initially tries to retrograde, but the Aleutian low is stubborn. After Day 12 the Aleutian low does back off considerably with the ridge retrograding. IF the Aleutian low weakens backing off sooner things are going to set up really nice. Cautiously optimistic.
