STRONG winds to more than 90kmh are set to buffet the Sunshine Coast on Thursday as a series of fast moving storms push through the south east from early afternoon.
The Bureau of Meteorology anticipates severe thunderstorms will be associated with a trough now moving through the Channel Country in inland Queensland and being steered towards the state's south east by powerful upper atmosphere winds.
Forecaster Chris Joseph said "serious" fast moving storms would begin pushing into the Sunshine Coast as Thursday's temperature hit a 30-degree peak just after noon.
"The main threat will be from the winds," he said explaining that if the systems had been slower moving they would generate more rain than the anticipated maximum of 8mm.
Mr Joseph said there was a real threat of winds to 90kmh and higher.
"The whole of the south east is in that zone," he said.
A squall line of storms was expected bringing the powerful winds from the west.
Offshore, northerly winds to 37kmh would reach 55kmh by evening with seas to 1.5 metres increasing to 2.5m around midday with an easterly swell remaining below a metre.
Mr Joseph said the trough would clear from Friday although thunderstorms may be present early in the morning.
Conditions would remain sunny and fine through to Sunday when another trough was expected to push through the south east repeating Thursday's instability.
Wednesday was expected to hit a peak of 28 degrees with light north westerlies early turning north north east at 15-25kmh then north west at 15-20kmh later in the day.
Thursday would hit 30 degrees off an overnight low of 18 with winds expected to increase from the north, north west.
Friday would be sunny following the chance of an early storm after a muggy night where temperatures were not expected to drop below 20 degrees. They would hit a peak of 31 degrees with winds north west early at 15-25kmh later turning south west at 15-20kmh.
Saturday will be partly cloudy though with only a slight chance of rain with winds expected to remain light throughout.
Sunday's maximum was expected to climb back to 30 degrees on a mostly sunny day but with an increased chance of rain as the expected trough pushes through.
Winds would be otherwise light.
