In the three days until Sunday, Hobart experienced its warmest weather this late in autumn in 74 years, averaging a maximum temperature of 21.5 degrees. Nights have also been warm during the past few days with minimum temperatures coming in more than four degrees above the May average. A strong cool change with a front and a low pressure system will see both the days and nights become cooler with widespread showers from Tuesday. Hobart's maximum temperatures will trickle off this week, only hitting 16 degrees on Tuesday, but by the end of the week the daytime temperature will only reach 11 degrees. Residents should be able to give the umbrella a rest next week as the low moves to the east and is replaced by a high. As the skies clear, however, overnight temperatures temperatures will plummet.
