The low itself does not pull in the heat, its an Arctic low hence its own cold air blob and low thicknesses. The warmth comes in via a ridge over the ESS and Chukchi but there's uncertainty just how much heat comes in and how long it lasts for. E.g on the GFS it looks brief but some signs on the ECM it may last longer.
Nullschool uses the GFS and auto-updates, usually a ~4.5-5 day forecast. Haha yeah, on nullschool anyway, it cuts off right as its centered in the Chukchi with some decent winds, heat, and moisture. Looks like it could continue to some degree, has some winds coming off Alaska, could be the impetus to break open the Beaufort channel if the winds don't do it over the next few days. Could be the straw that breaks up some of that turquoise/dark coast ice in the ESS + Chukchi too, since that side of Eurasia heating up. We'll see.
Low pressure system over the next few days will probably help expand that body of water in the Laptev, and most of that "ice" on the inner Severnaya coast (island between Kara and Laptev) is basically just rubble pushed up against it, so likely to open up a bit in some fashion. Ice in more northern Laptev where winds are blowing might be worth paying attention to given the state of things.
Cyclone coming looks like it's going to be pretty effective. Kara tongue will continue to get beat up, Svalbard going to get it, we'll see what happens to the FJL ice. If the low pressure winds open up the inner Severnaya coast and the body of Laptev water expands, all the ice between the Laptev + Kara gets a lot more interesting pretty quick.
Will be an interesting next 5 days. Eurasia starting to heat, looks like warmth starts to peak over into the CAA a bit towards the end of it. Good northerlies heading down Baffin, Hudson gets a bit too. Atlantic may play a more important role this year.
