The Wikipedia page for Molina de Aragón, which you linked to, says that the average low in January for that locality is -3.5C, and that the record low is -28C, which happens to also be the record low ever recorded in the whole of Spain (still according to the Wikipedia page).

-25C is thus certainly newsworthy and, well, that's in central Spain, which is elevated, but "central Spain" does not imply that it isn't and Spanish geography is what it is. This is not misleading.
