Stormy Skies and Shifting Temps: Toowoomba Braces for a Humid Sunday

Sunday Forecast Overview: A Mix of Sun and Storms

Residents of Toowoomba should keep an umbrella handy today, Sunday, 22 March 2026. While the morning may start with relatively calm conditions, local meteorological data suggests a shifting pattern as the day progresses. The region is expected to experience a maximum temperature reaching between 24°C and 28°C, with overnight lows dipping to a cool 15°C. Humidity levels are expected to be high, particularly in the early hours, contributing to a somewhat muggy feel throughout the day across the Garden City.

Morning: Cloudy Starts and High Humidity

The day is set to begin with a significant amount of cloud cover and mist, typical for the Toowoomba Range at this time of year. Early morning temperatures will hover around 16°C to 18°C. There is a moderate 30% chance of light showers during the early commute and breakfast hours, though no significant accumulation is expected before midday. Humidity will be at its peak during this period, potentially reaching as high as 98% at dawn, before settling into a range of 55% to 69% as the sun rises higher.

Afternoon: Thunderstorm Risk and Peak Heat

As we move into the afternoon, the probability of precipitation increases significantly. Current predictions identify a 60% chance of rain, specifically highlighting the risk of a thunderstorm developing between 1:00 PM and 4:00 PM. While the total expected rainfall is modest—estimated at approximately 1mm—the potential for sudden electrical activity and increased wind speeds means outdoor plans and sporting events should be monitored closely. Temperatures will hit their peak of 24°C to 28°C during this window, though the prevailing cloud cover may provide some relief from direct UV exposure, which is currently rated at a moderate level 5.

Evening and Night: Clearing Skies

The weather is expected to stabilize by the early evening. The risk of storms will diminish as the sun sets around 6:01 PM, with skies becoming mainly clear and calm. Temperatures will drop steadily toward the overnight low of 15°C. This clearing trend is predicted to continue into the start of the new work week, providing a crisp and pleasant end to the weekend for local residents.

Wind Conditions and Safety Notices

Breezes will primarily originate from the East and East-North-East, maintaining a steady speed of approximately 19 km/h to 22 km/h. Residents should be aware of occasional gusts reaching up to 29 km/h, especially during the potential afternoon storm window. While there are currently no severe gale or flood warnings in place for the Toowoomba region, the combination of high humidity and atmospheric instability suggests a day of unpredictable conditions. No formal alerts have been issued by emergency services, but standard caution is advised during any lightning activity.
