Only 2 days now till this storm is predicted to start bombing out over the CAA, EC/Windy now has central pressure getting down to 969 a day or so later as it crosses to the CAB, witha huge wind field, with 30-40 knot winds gusting well over 50kt in places. Could this open Parry Channel and the main NW passage route? The Lincoln Sea and areasnorth of Ellesmre Island and Greenland are in for another (last?) bout of strong southerly wind, well above freezing. The gap may widen again before refreeze
Anyway, its an interesting climax to the season. Both models havethe CAA low taking over the Pacific and Canadian of the CAB. With a lot of wind, not quite as strong, but pressure remains around 980 for a while. As that goeshe GFS sees a narrow ridge from Greenland to the New Siberian Islands by D7 and a 'double diplole' as lows also swirl in the Barents and Atlantic fringe. Its dispersal vs melt vs the clock, as temps inevitably drop
