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.
