The heatwave that has cooked South Australia for the past week increased in intensity by several degrees today. Overnight minima in a band across the west coast and central north down to Adelaide were some 4 or 5 warmer than yesterday, putting them 8 to 15 above the January average. Port Pirie's minimum of 32.2 was a whopping 14.9 above normal. Daytime temperatures also stepped up a couple of degrees, with all except the far SW and SE of the state recording maxima between 40 and 45. Notable highs and variations from normal are shown at left.

Substantial thunderstorms developed on the Qld Darling Downs and NSW Northern Tablelands and Slopes today. Warwick appears to have been hardest hit with 23mm and small hail falling in a storm just before 4pm, which also brought wind gusts to 81km/h. 16.2mm fell in 18 minutes to 3.53pm at the height of the storm. Around 3,000 homes lost power on the Darling Downs due to lightning strikes. Powerlines were reported down in Warwick, Toowoomba, southern Brisbane suburbs and the northern Gold Coast. Earlier, Barraba on the NSW NW Slopes recorded 22mm and hail in a storm, while hail to 3.5cm diameter was observed 20km east of Inverell around 6.30pm. Winds gusting to 93km/h destroyed three sheds and ripped branches off trees with a storm at Narrabri.

Strong winds and lightning strikes with a thunderstorm squall line caused damage in and south of Darwin, NT. Power blackouts in Darwin were widespread, with 1438 lightning strikes recorded in two hours.
