Warm spring conditions could develop into thunderstorms across south-east Queensland with the potential to produce hail this week.
Maximum temperatures are expected to exceed 30 degrees Celsius in Brisbane (31), Ipswich (34) and Toowoomba (30) on Monday after the weather bureau briefly issued a severe thunderstorm warning for Moreton Bay on Sunday afternoon.
Bureau of Meteorology forecaster Brandon Creagh said potential thunderstorm activity could hit south of Brisbane from Tuesday.
"We have a few troughs making their way across the state, which is going to give a bit more fuel to those showers and thunderstorms developing," Mr Creagh said.
"You might see some large hail for south-east Queensland, closer to the New South Wales border around the Gold Coast and as far inland as the Granite Belt."

He said the potential for storm activity was slightly above average for October and added that storms could impact Brisbane.
"Given that it's so close and forecasts do move around a bit, I wouldn't say that it's impossible for Brisbane to see a severe thunderstorm this week,"
Mr Creagh said.
He said showers were expected to persist across southern areas until Thursday.
"It's looking like showers and thunderstorms are going to stick around for a while through Wednesday into Thursday for a pretty wide area of the state with not much of a settling down as we approach the weekend either," Mr Creagh said.
Rainfall totals are expected to vary across the state, with heavy falls possible for the Gold Coast, while parts of Queensland's far north could receive little to no rain.
"You could see between like one to 20 millimetres. So a pretty wide range," he said.
"Then if you do get a severe thunderstorm or a heavy thunderstorm, you could get in around 20 to maybe 50 millimetres out of that."

Gold Coast resident Catherine Love, who was enjoying a barbecue with her friends in Burleigh on Sunday, said she was not concerned about the incoming weather forecast.
"We're going to enjoy this beautiful sunshine while we have it, and if it rains, we'll enjoy the beautiful rain too,"
Ms Love said.
Isolated showers and thunderstorms are also possible for Chinchilla, Rockhampton and Mackay.
Meanwhile, a maximum temperature of 38C is forecast for Mt Isa on Tuesday.
Central Queensland temperatures are also expected to hover around the mid-30s before dropping to the low-20s later in the week.
"It'll feel a little bit cooler if you do get caught in those showers, but outside of that, it'll feel pretty warm for the first half of the week especially, and then maybe dipping below average a bit for the second half," Mr Creagh said.
