Rain is expected in parts of the region on Christmas Day as a cooler change moves into the region.
Meteorologist with weatherzone.com.au, Rob Sharpe, says while above average temperatures have been recorded throughout December it's expected to cool down significantly for Christmas Day.
He says rainfall is expected across both the Northern Tablelands and North West Slopes and Plains weather districts, with more likely in the southern parts.
"Christmas Day we're expecting a few showers to be about and it could be quite wet in some parts of the North West Slopes and Plains and the Northern Tablelands, but some parts may miss out [because] it's going to be a bit patchy," he said.
"There is also the risk of thunderstorms within the region and they could be fairly heavy."
Rob Sharpe says cooler temperatures will be experienced at Christmas, but conditions are expected to warm up again by the weekend.
"For Tamworth, the last 15 days of December have been above the long-term average for December and that's been a feature across the Northern Tablelands and North West Slopes and Plains," he said.
"But, until the temperatures rise again, we are going to see a cool change on Wednesday, Christmas Day.
