Widespread rain and thunderstorm activity will affect Queensland and NSW over the next two days, with severe thunderstorms possible in both states.

It has only been two days since a line of violent storms swept across Qld on Sunday, causing large hail, damaging winds and prolific lightning. This included 5 cm hail in some southern suburbs of Brisbane and a 109 km/h wind gust at Gayndah.

Sunday’s thunderstorms produced a huge amount of lightning over Qld, with 795,000 strikes detected within an 800 km radius of Emerald during the 24 hours ending at 6am on Monday. Around 77,000 of these strikes, or about 10%, occurred within 100 km of Brisbane.

Positive lightning accounts for less than 5% of all strikes, and it is typically stronger than most other lightning strikes. Source: @withinblackandwhite / Instagram

Looking ahead, rain and thunderstorms will persist over parts of Qld and NSW on Tuesday and Wednesday as an upper-level trough moves over eastern Australia.

Thunderstorms over the next two days are generally expected to be less intense than the supercells that hit parts of Qld on Sunday. However, severe thunderstorms are still possible in both states, particularly over northern NSW and central Qld on Tuesday, and central eastern Qld again on Wednesday. Rain will also be widespread across the two states, affecting both Brisbane and Sydney.

Large hail, damaging winds and heavy rain are a risk with severe thunderstorms that develop in the next couple of days. Be sure to check the latest warnings in your area for the most up to date information.
