Australian Severe Weather storms hailstorms and hailstones

Hailstorm and Flash Flooding near Bathurst 10th January 2019

Published by:

Today's chase began a little late. Made to the Mt Victoria and Lithgow area with storms already brewing and a severe thunderstorm warning (advice) in place. After monitoring the region near Port;land, I decided to head west over the range to clearer air. The constant rumbles and distant loud thunder also meant a storm was in the region.

Just east of Bathurst, several cells approached on radar towards Mudgee and Kandos - the southern cell approached my vicinity. Outflow from the storms near Oberon fed a nice updraft base developing ahead of the southeast propagating cell. The base consolidated rapidly and showed inflow characteristics for a short while. A barrage of lightning ripped from this beautiful base with green tinge. The lack of shear though saw a collapse into a high precipitation cell with hailstones to about gold ball size though most 3 to 4cm in diameter. Persistent heavy rainfall including some flooding and streams of water across paddocks was also widespread. Unfortunately, the 20 to 30 minutes deluge melted the hailstones to 1.5 to 2cm in diameter rendering measurement meaningless.

After an attempt to head south ahead of the southern cell, it was clear the storms had already utilised the energy. Lightning and rain followed me back to Sydney.
