Heat sweeping across the southeast

James Casey, Monday January 11, 2016 - 12:33 EDT

The next few days are set to heat up across the southeast with Adelaide, Melbourne, Canberra and Sydney all set to see two to three days above the mid 30s.

A very hot airmass is filtering in ahead of a slow moving trough, bringing a hot spell for the southeast of the nation.

Adelaide and Melbourne will see heat gradually build from today. It should reach the mid 30s today for both cities despite cloud and the odd shower lingering throughout the day.

Tomorrow will see Adelaide continue to warm, reaching the mid to high 30s, while Melbourne has a day off from the heat as a weak southerly change keeps the temperature below 30.

For both Adelaide and Melbourne the heat will peak on Wednesday. Temperatures will soar into the high 30s with the potential to tick over the 40 degree mark.

For Canberra and Sydney it is a similar story. The heat will begin today and gradually build to a peak on Thursday.

Canberra will see the next four days exceed 35 degrees, which hasn't occurred in January since 2014.

Meanwhile in western parts of Sydney, the temperature will reach the high 30s today and tomorrow before a slight dip with a southerly change on Wednesday. The heat will return with a vengeance on Thursday, soaring above 40.

For coastal parts of Sydney it will be five to six degrees cooler as the seabreeze moderates the temperature. Tuesday may be the exception as a hot and dry westerly wind could bring the hot weather to the coast.

A southerly change will bring the end to this spell of heat across the southeast. Adelaide will see the change arrive on Wednesday afternoon, while Melbourne, Canberra and Sydney will see the change arrive on Thursday, in the morning for Melbourne, middle of the day for Canberra and in the evening for Sydney.

This southerly change will bring cool showers and blustery winds, dropping the daytime temperature by 15 to 20 degrees. By the weekend the sun will make a return allowing temperatures to heat up closer to average for the start of the week.
