A rare November tornado moved through Taranto, (YouTube video<\/a>, AccuWeather blog entry<\/a>) in southern Italy, on Wednesday November 28th. A loop of 10.8 \u00c2\u00b5m Meteosat-9 imagery (above) shows the development of an overshooting top in a thunderstorm that is moving over Taranto between 0900 and 0915 UTC (Note that the time indicated on the satellite image is the nominal time<\/em> — the time that the satellite starts<\/em> scanning. The actual<\/strong> scan time over southern Italy is approximately 10 minutes later than the nominal time). Such cloud-top features are frequently associated with severe weather. A faint suggestion of an enhanced-V\/thermal couplet is apparent in the later imagery as the strong thunderstorm moves northward across the Salento peninsula and then into the Adriatic Sea. METOP-A infrared imagery (below) shows the thunderstorm complex about an hour before a tornadic storm moved inland from the Ionian Sea. The corresponding Meteosat-9 image is here<\/a>. The higher spatial resolution of the polar orbiter METOP-A allows the discernment of much finer detail in the cloud-top features. <\/p>\n

Visible imagery from Meteosat-9, above, also shows the development of the overshooting top associated with the tornadic cell. A higher-resolution visible imager from METOP-B, below, showed the line of thunderstorms in which the tornadic cell, indicated by the yellow arrow, was embedded.<\/p>\n

The tornadic weather was associated with an exceptionally deep extratropical cyclone. On Monday, that system was over the northwestern Mediterranean (see below), with ample evidence of exceptionally cold upper-level air over the Bay of Biscay. This storm also had a history of producing supercellular thunderstorms, as evidenced by the storm development just south of France in the animation below.<\/p>\n
