Looking at the latter, there are at least two pictures depicting snow in the Eastern/South Eastern portions of the Coerthas, as well as to the direction of Dravania. If Coerthas can have random portions with snowfall, why can't Mor Dhona *shrugs*
Even if it makes no sense..
Though, they could always flip Mor Dhona counter clockwise and makes its current East into it's North, matching the old east of Mor Dhona to the South East snowy portion of Coerthas giving it an excuse to be snowy
