The mercury refused to drop below 26 degrees for Adelaide last night, bringing a warm and muggy night ahead of a hot day today.
Yesterday saw the temperature rise above 35 degrees in South Australia's capital, 10 degrees above the November average. This is the first time in eight months that Adelaide has seen this kind of heat.
There was little relief for the city overnight as cloud cover limited cooling, making it the warmest November night in nine years. In fact, last night was warmer than the average maximum daytime temperature for this time of year.
Since sunrise the mercury has continued to increase, with thermometers reading 36.8 degrees at about midday. With the city reaching 35.9 degrees yesterday this makes it the warmest two-day November spell in three years.
Northwesterly winds ahead of a slow-moving low pressure trough are dragging hot air from central Australia where it has been reaching the high 30s all week.
Early this afternoon winds will turn from northwesterly to westerly, bringing a gradual cooler change, taking the temperature to the low 30s. By 12:30pm this westerly change had cooled the airport and some beach suburbs from 35 degrees to below 30. Late afternoon or early evening wind will turn southwesterly, cooling the city below 30 degrees, dipping to the mid 20s by about 8pm. Tonight will eventually cool to about 16 degrees, 10 degrees cooler than last night.
A trough building over South Australia will produce showers in Adelaide tomorrow, with the city only likely to warm up to the low 20's over the next couple of days, giving some respite to current conditions. Though, this cooler weather is unlikely to last long with heat returning as early as this weekend.
