The thunderstorm cluster just north of Sicily that we reported on earlier, is showing very robust development. The system shows very impressive morphology, with a very strong leading updraft with a prominent overshooting top and several trailing updrafts, a large backsheared anvil and a strong flanking line. Radar coverage is poor, but the trailing part of the cluster is covered by composite radar Italy and showing isolated cells within the cluster.

Conditions in this area are currently very conductive for explosive formation of supercells. A very sharp surface convergence is present north of Sicily ahead of the cold front. A 40-45 kt WSW mid level jet is present and E-SE backing surface winds. High CAPE is present in the area due to strong WAA with WRF models predicting 2000-3000 J/kg NW of Sicily. This area is part of the updated MDT risk area of Day 1 Outlook 11/10/2013 with main threats for heavy convective rain, large hail, severe winds and even tornadoes.
