Weatherzone meteorologist Brett Dutschke said this week in Bathurst has been the hottest of the season so far and it would only get worse on Friday.

“It is all related to the heat we have at the moment; it is all sourced from north western Australia, where it was reaching the mid-40s,” he said.

The wind has drawn the weather across the country to Bathurst, which is why the temperatures have been increasing, Mr Dutschke said.

The average temperature for this time of year is 29 degrees, making Friday’s predicted temperature nine degrees higher.

Mr Dutschke said there is the chance it may even get to 39 degrees on Friday.

“It will probably be the hottest day in two years and there is the outside chance it will be the hottest day in four years,” he said.

Residents will get a slight reprieve from the heat on the weekend.

“[Friday’s temperature] is just ahead of another cooler change and that will come through Friday night or Saturday morning,” Mr Dutschke said.

“That cooler change has the chance of bring rain and a storm.”

Saturday is expected to have a maximum temperature of 31 degrees and there is an 80 per cent chance of rain.

On Sunday, the temperature should drop slightly to 27 degrees and the potential for rain will be just 20 per cent. 

The temperature will start to increase from Monday, with the mercury expected to hit 32 degrees ahead of Tuesday’s forecast of 35-degree temperatures.
