A severe storm developed on the southern border ranges and moved northeast towards Beaudesert, eventually merging with a line of storms moving east from the Darling Downs to form a squall line which moved northeast across the Southeast Coast district. The line continued to develop northwards and ultimately moved through both the Wide Bay and Capricornia districts as well. Gusty winds and heavy rainfall were the predominant effects of the storms but hail up to 10 cent piece size was reported from some Brisbane suburbs and the Nanango area. Tree and power line damage was reported from northern Brisbane suburbs. Minor flooding was also fairly widespread in the Brisbane area
