After a day of extreme heat, thunderstorms dumped heavy rain on parts of central and southern QLD on Thursday.
In the Maranoa and Warrego it was Roma's hottest day in at least 19 years of records on Thursday, hitting a scorching 44.6 degrees. Charleville reached 43.5 degrees for the first time since 2003, while Mitchell hasn't had a hotter day since 2001, hitting 43.1.
To the northwest, Longreach sweltered through their hottest day in 16 years, tipping 46.2 degrees. Meanwhile, it's been six years since Blackall and Cannington were as hot, reaching 44 and 45 respectively.
The extreme heat combined with a low pressure trough to generate thunderstorms, sparking up over the Darling Downs and Granite Belt in the early afternoon and becoming more widespread into the evening.
The storms brought heavy rain and strong winds. Some of the heaviest falls were in Toowoomba where 66mm fell to 9am on Friday, including 15mm in ten minutes. This is the heaviest rain the town has seen since November 2011.
Storms also delivered 24mm to Inglewood and wind gusts of up to 74km/h, while 11mm at Miles marked their heaviest falls in a year.
The storms petered out before reaching the state's southeast, although building cloud trapped heat near the surface. This lead to the warmest night in seven years for both Brisbane and the Gold Coast, with only cooled to 26 degrees and 25 respectively.
Friday will be another day of extreme heat, with thunderstorms likely to spark up again during the afternoon and evening over the southern and central interior.
