Warming continues in the stratosphere, as does weakening of the spv stratospheric polar vortex
If 10hpa 60N zonal mean zonal winds reverse to an E'ly for 24hrs or more a technical ssw sudden stratospheric warming event may well be declared, even if short lived

The spv stratospheric polar vortex is currently weakest on record for 23rd November, as we await to see if a technical ssw major sudden stratospheric warming event plays out

10hpa 60N zonal mean zonal winds have weakened from W'ly 70mph to nearer 12mph over the past 10 days or so, and this is leading to warming over the N Pole through vertical compression..the warming currently more notable at the 30hpa level than at 10hpa

Both EC and GFS have generally been hinting at a fast recovery of the spv stratospheric polar vortex following its current period of significant weakening, for atleast 10 to 14 days
Both continue to show this
Will be interesting to see if this comes off 📉📈

With the imminent weak polar vortex/potential SSW, one similar recent(ish) year is 1996/97, which saw a very weak early season vortex (date-record weak U10-60 in Nov). 96/97 also had an established easterly QBO & cool ENSO Neutral/borderline La Niña. Extremely strong late-season vortex ensued.

Current location of all the gritters and snowploughs out in force keeping Scotland's main roads snow free..
Such hilarious names given to them too...😅...
