Brisbane Chills: Rain to Dampen Spring Temps

Brisbane is expected to remain colder than other Australian capital cities on Monday, with forecasts indicating a temperature of only 20 degrees Celsius. This cooler weather is attributed to a band of rain situated over the state's south-east, a pattern driven by moist easterly winds interacting with an inland trough.

This weather system is predicted to persist until early next week, bringing substantial rainfall to Brisbane and surrounding areas. By the end of Sunday, the city could receive up to 150 millimetres of rain. Recent observations show inner-northern Brisbane and bayside suburbs experiencing heavier downpours.

Forecasters warn of a potential for flash flooding, especially in urbanised environments where water absorption is limited. While temperatures are expected to rise throughout the week, thunderstorms are forecast for Wednesday and Thursday, with the heaviest rains anticipated later in the week.

Despite the persistent wet conditions, pockets of clear weather are expected, including easing rain on Monday afternoon and fine breaks on Tuesday. This follows a period of unseasonably warm September days in Brisbane, with October already recording significant rainfall.
