RAIN and cool conditions gave reprieve to Hunter firefighters over the weekend, helping to bring fires threatening the region back under control.
Temperatures crashed at the weekend, following record highs of up to 45.2 degrees on Friday.
Lake Macquarie, which notched the hottest spot in the Hunter, dropped 20.1 degrees by Saturday before recording a mild 21-degree high on Sunday.
Nobbys followed a similar pattern, falling from 42.5 degrees on Friday to 21 degrees on Sunday.
The cool-off was welcomed in the fire-struck Coalfields, one of several parts of the Hunter to record more than 10 millimetres of rain on Sunday.
Weatherwatch meteorologist Anthony Cornelius said the cooler trend may continue for the week.
Mr Cornelius said a spell of hot north-westerlies would likely swing around to blow moisture off the ocean into the region.
"It's likely we're going to get a few showers right through into next weekend," he said.
"It's still going to be quite warm and humid and there will be some isolated thunderstorms but most of the activity looks like it will be inland."
NSW Rural Fire Service Lower Hunter duty officer Inspector Glenn Byrnes said firefighters were grateful for the change after battling blazes in sweltering heat last week.
But he said firefighters remained alert, running patrols throughout the weekend to keep fires, including Aberdare, under control. They were also vigilant for new fires, he said.
"[The Aberdare fire] will be monitored for the next couple of days."
"With a major fire patrols are pretty regular, just observing and putting out any hot spots."
Inspector Byrnes said firefighters were hopeful the recent threat and forecast lull in dangerous conditions could prompt more home owners to compile bushfire survival plans.
