Thursday saw a welcome return to thundery skies for parts of northeastern New South Wales and also southeastern Queensland. Thunderstorms developed through parts of both regions yesterday afternoon producing localised strong wind gusts and large hailstones across multiple locations. Activity remained quite slow moving and isolated, therefore only a few locations experiencing severe weather.
The first Severe Thunderstorm Warning for the region was issued by BoM NSW at 2:26pm, warning for severe thunderstorms that could potentially produce damaging winds and large hailstones for the Lismore, Murwillumbah, Byron Bay, Ballina, Casino and Kyogle areas.
Just over an hour later, the Bureau of Meteorology QLD issued a Severe Thunderstorm Warning for damaging winds and large hail at 3:38pm for slow moving thunderstorms along the coast moving northeast, and affecting parts of Caboolture, Deception Bay and Beachmere.
A secondary thunderstorm over the northern Gold Coast yesterday afternoon also prompted a Severe Thunderstorm Warning from the Bureau, for the areas of from Mount Tamborine through to Coomera for damaging winds and large hail.
Large hail was observed in numerous locations across the South East yesterday with 2-3cm hailstones observed at Caboolture and Morayfield, with a large accumulation of small hail observed at Springbrook during the early afternoon. South of the QLD border, hail to 3.5cm was reported from the Clothiers Creek with hail to 2cm reported from Dunoon, Federal and through to Casuarina and Kingscliff, as thunderstorms tracked to the northeast over the Northern Rivers and the Tweed Valley region of NSW late yesterday.
Despite the lack of surface moisture, thunderstorms did produce some nice structure as detailed in the photos below.
