Severe-weather. eu continue to publish in depth analysis of the science of weather.
related Phenomena.
This article from the link below shows Arctic ice extent since satellite imaging in 1979. The long term average is based on 41 yrs of data. They call that long term average but really that is misuse of the adjective’long’ .
None the less the report discusses the current situation of a slow start for ice build.
The report discusses in detail factors that affect ice extent and the implications for Northern hemisphere mid latitude weather for the rest of January 2021.
Factors discussed include salinity patterns, polar vortex split, synoptic patterns at the surface , La Niña influence and jet stream behaviour.
The forecast for areas most affected by polar cold intrusions at surface layer is outlined with lots of graphics

I have been following Hudson bay ice form up for 3 years and this year it froze all the way to Ontario 8 days earlier than normal.Polar bears with 3 cubs were seen on the ice.How much longer can it be claimed all the ice has gone.Canada experienced -20 and lower temperatures in February and the ice spike went all the way to Texas.Guess what happened to sea levels during this period.Nothing at all.when Texas power and water went down for 4 days I checked and it was -25 in the Arctic circle and -27 at Antartica.Ice does not melt at them temperatures but it would seem that a week of -20 will freeze the ocean as it did at Cape Cod.I consider myself a realist and base my assumptions on what I see.My mother inlaw lives in Portsmouth U.K.and it was snowing.I could see it when she was chatting on skype with her daughter and grand daughter.
