A couple of scorchers are on the way for Adelaide, Melbourne, Canberra and Sydney over the next few days. How hot will it get?

A hot airmass ahead of a low pressure trough will sweep across the southeastern capitals, starting with Adelaide. It is expected to heat up in the South Australian capital today, reaching 34 degrees ahead of tomorrowâ??s thundery change. These storms should arrive on Monday morning bringing widespread falls of at least 5-10 millimetres.

The hot air will shift to Melbourne tomorrow, making it a sweaty day for the those in town to watch the Australian Open. The Victorian capital should reach 35 as cloud builds throughout the day. The roof at Rod Laver may need to be put into use as a few millimetres of showers are expected to develop in the afternoon.

Canberra will see a pair of hot days tomorrow and on Tuesday, both days reaching 35 degrees. The heat will come to an end for the ACT on Tuesday afternoon as the trough sweeps across causing cloud to build and a few showers are likely. 

On Tuesday, the thermometer in Sydney is expected to soar the highest, reaching 38 on the coast and 42 in the west. Hot northwesterly winds will see the temperature rapidly warm up in the morning before a southerly change cools things down in the afternoon. Showers and possible thunderstorms with the change will bring 5-10 millimetres.

The next round of heat across the southeast is expected from Friday 27th but it isnâ??t looking to be quite as hot.
