Over the last week southern Queensland has seen a series of chilly mornings. Despite these cold mornings, days are still warm and sunny. Starting off in Brisbane, morning temperatures have been below the May average since last Saturday, with the coldest morning coming last Sunday at only 10.7 degrees. This trend does not look like it ease up for the next few days with minimum temperatures around 10 degrees forecast until Wednesday. These chilly mornings should ease from Thursday, but the tradeoff will be slightly cooler days. The cool mornings have not been limited to the metropolis either, with the southwest also experiencing some chilly starts. On Saturday, Warrick saw a minimum temperature of 0.3 degrees, a whopping 6.7 degrees below average, and again this morning saw the mercury drop to 1.1 degrees. Early morning respite is unlikely for some time, with mornings forecast below five degrees until the end of the week. Roma has been experiencing a run of cold mornings for over a week, and just yesterday, got down to 1.5 degrees. The forecast for Roma is also looking cold, with near freezing minimums until Wednesday. With all these chilly temperatures frost looks to become more extensive in southern Queensland for the next few mornings. The cause of all these chilly starts is a cold airmass and an extensive high pressure ridge that has been sitting over the state. This has led to clear skies and light land breezes in the mornings. Conversely, it has also been allowing temperatures to heat up during the day.
