cut off low out in the central atlantic is forecast by gfs and euro to linger south of the azores and maybe drift southwestward. that looks like a reasonable setup for an out-of-season storm originating in that area at this time of year. it's an upper low w/ surface trough right now, and should form a closed deep-layer low before long, maybe until around the new year. gfs doesn't show a warm-core transition, though, and suggests it will try to elongate like a frontal trough as the upper cold low weakens. given the latitude (25-30N) it isn't impossible, but a long shot at this point for sure.
merry christmas everybody.
