Some places in Queensland had their hottest day in four years on Monday as heatwave conditions intensify across the state. As of 3pm EST, the highest temperature in the state was 45.4 degrees at Thargomindah. Rolleston (42.7C) and Rockhampton (41.0C) were both having their hottest day since 2014. This is also Rockhampton's hottest February day in 46 years. Brisbane's apparent temperature at 3pm was 36 degrees, which was three degrees higher than the actual temperature due to humidity. The heat will linger over Queensland for most of this week, producing a severe to extreme heatwave across most of the state. Today's heat is also helping trigger thunderstorms in the southeast and warnings were issued shortly after 3pm for damaging winds in parts of the Wide Bay and Burnett District.
