It seemed doubtful we’d reach the promised 29C yesterday. At lunch time in Brisbane it was still only a mild 25C. But the temperature continued to rise in the Northerly winds until it reached exactly 29C at 3pm. It was cooler on the coast at Redcliffe with 27C. Between 3pm and 4pm the wind swung around to the West South West as the cold front from a low in the Tasman Sea swung through.
A cold front is a wedge like mass of cooler air that pushes the warmer air ahead of it up. Cold fronts can sometimes produce severe weather and thunderstorms. In this case there were some small weak showers around the Border Ranges and Tweed River area.
Behind the cold front the South-Westerly winds have been quite blustery, with wind gusts hitting up to 41km/h in Brisbane and up to 54km/h at Brisbane Airport. The strongest gust was 72km/h at Cape Moreton at 8:03pm last night. Gusts are still above 40km/h there now at 7am. Winds in Brisbane have moderated this morning.
Russia apparently has the largest per capita concentration of dashcams in the world. This video was recorded yesterday. It looks to me to around F1 or so on Fujita scale. It does a pretty good job of the roof but doesn’t move the car or knock down walls.
Hopefully as dashcams become more common here we’ll start to see a lot more footage of rare weather and sky phenomena.
If you’re in South East QLD you’re likely already feeling the spring warmth coming from northerly winds. They’re still pretty light at the moment, but they’re bring in warm air from northern central Australia across the eastern coast. This is producing warmer than average temperatures.
Later in the week a pre-frontal trough and cold front will move through moving us back to cooler temperatures again. There’s still a bit of cool weather ahead of us, but the worst has passed!
