Warm front or occlusion you decide

The mild air is returning to the southwest this afternoon. I can’t decide if it’s a warm occlusion, a single warm front, or an occluding frontal system of some kind. All I do know that it’s cold on the surface in the southwest ahead of it, and somehow the milder air has overridden the colder air along way ahead and to the northeast and prevented it from snowing more widely on lower ground, although that may well be happening on the highest ground of Dartmoor and Exmoor. Who knows the warm front itself might lie much further to the northeast as an upper feature and the cold surface in the easterly flow is just masking its presence.

What do you think?
