More hailstorms expected during the hot spring ahead
SUNDAY'S hailstorm at Pottsville was caused by atmospheric instability and this spring's hotter temperatures could bring more of the same.
The isolated thunderstorm formed shortly after midday in Pottsville and surrounding areas, dropping heavy rain and hail, which measured about as big as a five cent coin.
"Essentially the reason why the hail arrived was because there was a lot of instability in the atmosphere which fuelled the storm," Weatherzone meteorologist Rob Sharpe said.
"There was also a dry layer in the atmosphere, meaning hail became a greater risk."
Mr Sharpe said this season was likely to bring a moderate increase in stormy weather.
"Because we're going to see quite hot temperatures across central Australia and warmer than usual temperatures off the coast that will create the necessary energy to create more storms than usual," he said.
Mr Sharpe expected temperatures would shoot into the mid-30s this week, reaching 33 or 34 degrees on Thursday.
He also warned that a storm could hit the Tweed on Saturday, but said it was more likely to occur further north or west.
