Supercell 3rd November 2012 near Emerald Queensland

See : 128km Radar Loop for Emerald, 07:00 03/11/2012 to 14:00 03/11/2012 UTC

Looks to have been a supercell this evening just after dark in the region south of Emerald. Deep layer shear and modest flow aloft coupled with moist air and surface heating must have exploded just after sunset. The concerned severe thunderstorm warning from the Bureau of Meteorology was for very large hailstones and destructive winds:

For people in parts of the
Central Highlands and Coalfields and
Maranoa and Warrego Forecast Districts.

Issued at 9:38 pm Saturday, 3 November 2012.

Severe thunderstorms are likely to produce destructive winds and large hailstones in the warning area over the next several hours. Locations which may be affected include Emerald, Blackwater, Taroom, Rolleston, Springsure and Carnarvon National Park.

Particularly dangerous thunderstorms are currently located on radar in the vicinity of the northern Carnarvon National Park and moving northwards towards the Springsure and Rolleston areas during the next hour or two. These dangerous thunderstorms are likely to produce destructive winds and very large hailstones.

    Thanks for posting those pictures Michael Bath – the storm definitely shows inflow dominance but it seems the storm was in a slight weakening phase? Looks a little elongated by the looks. Any news on the timing compared to radar?

    Murray I am glad you picked up in that ad I think the storm was progressing north along a boundary. I was talking about this situation with Michael Bath just yesterday. You get the impression the boundary was beginning to undercut this storm to becoming outflow dominant similar to the storm that occurred in Grafton with a mad five electrical show Michael and others got a year or two ago. Anyway nice to see someone onto it albeit I would love to have seen the storm earlier in its history.
