Brisbane has enjoyed unseasonable warmth so far during this long weekend, but the heat may come to end on Tuesday with the arrival of thunderstorms.

Brisbane recorded a maximum temperature of 28.7° on Saturday, and those temperatures are more typical for the capital city in November than October. Furthermore, temperatures soared into the low 30s on Sunday and temperatures are expected to reach the low 30s again today and Tuesday. With highs in the 30s, it will certainly feel like summer during the next couple of days.

However, this heat will come to an end later Tuesday. With a surface trough expected not far to the west, unstable conditions will develop across southeast Queensland. The atmosphere will be primed for thunderstorms to develop in southeast Queensland from late morning through to late evening, and there is the chance one of these storms will hit Brisbane.

Some storms in southeast Queensland may become severe on Tuesday, particularly during the afternoon and evening hours. The strongest storms could generate large hail, gusty winds and locally heavy rainfall.

For some locations, a significant temperature drop will be experienced during the passage of a thunderstorm or heavy shower. For those locations untouched by showers and thunderstorms, it may remain muggy until later Tuesday evening when a cooler south to southeasterly air flow arrives. Temperatures will generally fall to the lower 20s in the Brisbane area by late Tuesday evening. Looking further ahead, daytime highs are expected to hold in the 20s for the rest of the week.

On Wednesday, scattered thunderstorms are expected across southeast Queensland so be sure to keep up to date with the latest warnings.
