Brisbane will have a hot and stormy end to the week as a trough crawls over southeastern QLD.
Very warm northerly winds are being directed into the state's southeast today ahead of the trough, tapping into heat that built up over the nation's interior during the week.
Brisbane will reach about 33 degrees today before a sea breeze stops the mercury from rising further. To the west though, places like Ipswich and Gatton should reach about 37 degrees, making it their second hottest day since January.
The trough will move closer to Brisbane this evening, bringing a few showers and the chance of thunderstorms, most likely in the west.
Saturday will be another warm and humid one, although cloud, showers and thunderstorms will stop the mercury from climbing above the low 30s. Most of the storms will again occur to the west of Brisbane on Saturday, however the city can expect to see the heaviest falls on Sunday.
Showers and storms between Friday and Sunday have the potential to bring widespread rainfall totals of 20-30mm in the state's southeast, with some places likely to see more than 50mm.
Looking ahead, the trough will move off the coast and into the Coral Sea on Monday, allowing showers and storms to ease.
