A wet and windy morning has marked the end of Melbourne's warmest back-to-back October days in 18 years.
Showers developed in Melbourne last night as a low pressure trough passed over the city ahead of a cold front.
By 9am on Thursday morning, the city had recorded 3mm of rain, although falls were heavier in the east. Ferny Creek and Mt Dandenong both recorded 15mm, while Coldstream's 14mm and Scoresby's 10mm were the highest totals since September.
The showery change this morning marked the transition from a hot air mass to a cooler one, which is a common occurrence in spring.
The change brings an end to the summer-like temperatures of the last two days in the Melbourne. Tuesday and Wednesday both climbed above 30 degrees, making them the hottest consecutive October days in 18 years. In contrast, today will struggle to get above the mid teens.
In addition to this morning's showers, cool southwesterly winds are ensuring an abrupt change from shirts to jackets today. Winds gusted to 80km/h on Port Phillip Bay this morning and will become strong in the city during the day. Due to wind chill, temperatures will feel 3-5 degrees colder than they actually are.
Fortunately, showers and wind will ease during the afternoon as a high pressure ridge builds over the city from the west. Apart from the chance of just a light shower on Friday morning, the working week will end on a much calmer note with a top of 18 degrees.
