Hobart has been chilling through its coldest nights in 21 years but can now look forward to something a bit warmer.
The stagnant weather pattern has led to a run of five nights with an average minimum of just 0.9 of a degree, its coldest five-night spell since 1992. In that year it was also in June when there were five consecutive nights with an average minimum of 0.2 of a degree.
In the next few days a high pressure system which has been responsible for the long run of cold nights across Tasmania and Victoria, will finally shift east, allowing nights to warm up.
The high will make way for fronts, bringing an increase in wind and cloud, the main features which keep nights from getting so cold.
The next few nights should be much closer the June average minimum of 5.2 degrees. By early next week some nights will stay warmer than about 10 degrees.
Initially the fronts will be weak, containing relatively mild air and very little rain, hence also bumping up daytime temperatures.
In the past 12 days Hobart has not warmed past 11.1 degrees but should get close to 14 or 15 degrees each day from Thursday to the middle of next week.
Today the city had only reached 7.9 degrees by 4pm. If it stays below eight degrees until 9am tomorrow, this will have been its coldest day in two years.
