Tomorrow's weather conditions are not expected to be as severe as first forecast.
But, the Bureau of Meteorology says temperatures will still hit the high 30s around Coonabarabran.
The duty forecaster Sarah Hicks says there will be winds of up to 30 kilometres an hour.
"So we have a high pressure system which on Wednesday was sitting over the Tasman Sea and that's been bringing a little bit of northern to north-easterly winds but as the trough has approached, we're seeing those winds turn a little bit north-westerly and bringing in more hot air from inland Australia," she said.
The hotter weather is set to be followed by a cool change.
Ms Hicks says temperatures will then drop by up to five degrees at the weekend.
"When the change comes through on Saturday, we're expecting it to be around about the middle of the day.
"It's probably going to be similar wind strength as we might have seen the day before the change so maybe about 20-30 kilometres per hour and we're expecting temperatures to begin to drop once that change goes through in the middle of the day on Saturday."
