Thunderstorms brought the best rain in many months to areas of New South Wales and Victoria on Sunday, but some were also ferocious, bringing destructive winds, hail and large amounts of lightning. A broad low pressure trough lying across Australia's eastern interior was fed by humid easterly winds, providing more than enough fuel for widespread thunderstorms. By early Sunday afternoon, a gigantic line of storms stretched across NSW and into northern VIC, and continued to plough east into the early hours of Monday morning. More isolated storms also formed ahead of the line. The line of thunderstorms brought wind gusts as strong as 117 km/h at Hay and 120 km/h at White Cliffs, whilst in VIC a tornado hit Strathmerton, causing up to 10 homes to lose their roofs. Lightning was fierce across both states, with almost half a million lightning strikes between Sunday morning and Monday morning. Despite the chaos, substantial rain totals fell with the thunderstorms. In NSW, Gundagai and Temora both experienced their best rain since June 2013, recording 32mm and 35mm respectively in the 24 hours to 9am. In VIC, Wangaratta had its heaviest rain since January recording 27mm, whilst Eildon and Yarrawonga had their biggest falls since April, recording 14mm and 23mm respectively. The rain is hardly drought breaking, however further thunderstorms and rain on Wednesday and Thursday could bring further falls of 30-50mm across the region.
