For the second day running severe storms have dumped heavy rain on the saturated Toowoomba and Lockyer Valley area, and the storms are moving into Brisbane. Already these storms, which are moving northeast have brought more than 50mm of rain in 30 minutes to Romani, south-southeast of Ipswich. They are riding on a southeasterly wind change which is interacting with a lingering low pressure trough. There's a chance they will weaken before they reach Brisbane's CBD but on the way they have potential to cause flash flooding, large hail and damaging winds. They may last late into the evening, before weakening into thundery rain. Earlier today, 60mm of rain fell near Tenthill, southwest of Gatton, in just one hour. Gatton picked up 23mm, including 13mm in 10 minutes. Two-centimetre diameter hail was reported at Oakey, where 16mm fell, including six millimetres in 10 minutes. Yesterday, up to 30mm fell in the Ipswich area. On Thursday further storms are likely over southeast Queensland, although freshening southeasterly winds should keep the biggest ones away from the coast. The biggest storms, with 50mm potential, should become confined to the area north and west of Toowoomba.
