"A very well organised and unusual storm for late August."

"(A low) will cross Greenland mid week and sets it's sights on Iceland Friday into Saturday, deepening on approach," says Mark Vogan Blog. "This system will have some very cold air attached and while strong to gale force winds will likely be a significant feature, the most noteworthy aspect to this storm which pressure down to the mid 970s in millibars, could be the cold temperatures and snow"

"...this looks to be a very well organised and unusual storm for late August even though this fairly high latitude can and does seen deep lows at this time of year. It's the cold that comes with it which could well grab weather headlines this weekend bringing a rare late August snowstorm to Iceland.
