Only four days ago, the Victorian capital only reached 18 degrees, 6 degrees below average for December. However, yesterday, the city soared to 35 degrees, with the airport reaching 37 degrees, its hottest December day in 2 years. Today, the temperature has plummeted again, with the mercury only forecast to reach 20 degrees. This is 17 degrees cooler than yesterday, after a cold front moved through last night dropping the temperature 13 degrees in just 10 minutes. The cold front was also associated with strong winds with St Kilda recording a gust to 91km/h, and Avalon 85km/h, its strongest gust since September. The temperature is set to soar again rapidly, and as early as Wednesday the temperature should be back into the low 30's. Thursday is expected to be even hotter with a maximum into the mid 30's. Looking further ahead, the unpredictable temperatures should start to stabilise with the next front due around the end of the week, with temperatures set to return to around average.
