Thunderstorms gave some Darwin residents an early wake up this morning but fizzled out by sunrise. The storms formed more than 50km inland of Darwin, dumping 35mm of rain over Lambells Lagoon and 19mm over Middle Point in short time. As much as 10mm of this rain fell in just 10 minutes, leading to brief, minor flash flooding. These storms travelled west but died by the time they reached Noonamah, 30km from Darwin. Both Noonamah and Darwin Airport only recorded 0.4 of a millimetre in the rain gauge. These brief storms make it the fifth day this month that Middle Point has recorded some rain and has 27mm all up, more than half way to its October average of 50mm. Darwin's four rain days this month has only amounted to three millimetres, still 68mm short of the monthly average. Darwin and other parts of the western Top End are a chance for another shower or storm later today and on Friday due to a lingering weak low pressure trough. The trough should lose some oomph over the weekend, reducing the chance of showers and storms. Come next week, this trough should gain instability and moisture, making showers and storms more likely again. Darwin is even a chance for a brief heavy downpour, which would give residents some cooling relief from the high humidity.
