A hot airmass is building across southeast Queensland with high temperatures expected to be sustained for the next week. Brisbane's daytime temperatures are expected to average more than 34 degrees from today through to next Monday. This will make it the city's hottest week in nine years. Temperatures will peak over southeast Queensland tomorrow when the mercury will rise to 37 degrees in Brisbane and the low forties for inland parts of the southeast. Ipswich is expected to reach 41 degrees tomorrow, which would make it the hottest day in nine years and will be on track for its hottest week in 15 years. For the remainder of the week, daytime temperatures are forecast to reach 33 to 35 degrees each day in Brisbane. These high temperatures will combine with high humidity in the city making it feel even warmer. The hot airmass is filtering across the state from the west, where temperatures have been consistently hot since the start of the year. Birdsville has already seen average maximum temperatures above 45 degrees during the first week of the year and is likely to experience at least another week of similar heat. This will make it the hottest fortnight in its 57 years of records. The dry and hot conditions will affect much of western, central and southern Queensland during the next few days resulting in increased fire dangers.
