I guess when the barotropic system formed in -35°C 500hpA air to the northwest of Scotland, the surface conditions 800 miles to the south and 12hours later really didn't enter into the mix. It may have become more baroclinic now though.

100% Baroclinic now imo. After careful reading, it would suggest that it was a polar low when it was born. But, it became heavily modified since then. It would have been really interesting if it had slipped down the East coast- a touch out in the North sea. Nonetheless, It certainly caused a good stir. :)

Just goes to show how a tiny amount of height makes a difference here.

 

The slightly less cold Atlantic air getting into the flow definitely wont be helping either
