Central Queensland is bracing for a blast of heat, with temperatures to top 40 degrees Celsius in some areas.
It is expected to reach 41 at Clermont, 40 at Emerald and Biloela and 39 at Rockhampton.
Weather bureau spokesman Brendan Bradford says storms moved through the Central Highlands last night, bringing some rain and strong winds.
"We recorded an 82 kilometre an hour gust at Emerald and 9.8 millimetres of rain there," he said.
"Clermont had 1.2, Springsure 1.6, I got a report at Fairbairn Dam of 5mm and for the west of Springsure, Van Dyke Creek had 18mm, so some moderate falls in those thunderstorms but mostly just gusty winds."
He says some relief is on the way tomorrow, but there is a severe fire danger today.
"Very low humidity, very high temperatures, up to 41 degrees in Clermont and Moranbah, so very high to severe fire danger ratings and quite gusty winds in the north-west developing during the day," he said.
