"Damaging winds and heavy rainfall that may lead to flash flooding are likely."
"Large Hail and damaging winds are likely with storms near Warwick and Oakington."

EARLIER: Storms loom for southeast Qld with chance of damaging winds
ISOLATED storms are now affecting the Somerset and Toowoomba regions after a hot, humid day.

BOM warned the storms were severe and damaging winds were likely.
Other areas of Queensland are not currently including in the storm warning.
EARLIER: A LARGE, humid, unstable air-mass is sitting over south-east Queensland this afternoon and the Bureau of Meteorology is saying this could lead to storms and damaging winds in some areas.
Queensland Duty Forecaster Annabelle Ford said while no storm warnings had been issued there was a good chance they would be, this afternoon.
"Over the whole of south-east Queensland there's a really unstable air-mass," she said.
"The conditions are probably good for storms but storms can always be really hit and miss - so they could be in one area but not everyone will get one."
Severe thunderstorms are likely in parts of SE #DarlingDowns this afternoon/evening and possible south of #Gympie. Damaging wind gusts are the most likely severe weather! #QldStorm #SEQld pic.twitter.com/VJEWIlusWw— Bureau of Meteorology, Queensland (@BOM_Qld) February 13, 2018
This afternoon the BoM uploaded a map to Twitter saying severe thunderstorms were possible, or likely, for most of the state's south-east.
Non-severe or damaging storms are also possible for most of central coastal Queensland and much of the Cape, according to the forecast map.
"That's kind of indicative of where the moisture is," Ms Ord said of the map.
"In the south-west corner there's some really dry air so while storms are possible there they're more likely in the areas where there's more moisture."
Ms Ford said the nature of the system involved meant it was unlikely to lead to hail, however, she said there was a good chance of strong winds for the area south of Toowoomba.
Ms Ford said that was due to a technical fact about the system which she referred to as wind-shear.
Essentially this means the direction of the winds blowing along the earth's surface, or lower atmosphere, is different to the direction of the winds in the upper atmosphere.
"At the moment we have light north-easterlies in the lower atmosphere and then strong westerlies in the upper atmosphere," Ms Ord said before adding that wind-shear like this often increases the severity of strong winds during a storm.
