Winter is coming ... cold snap finally on its way
WE'VE had a good run, but Grafton residents might want to put an extra blanket on the bed tonight.
For the first time this year, since September in fact, the temperature is forecast to drop below double digits.
A low of eight degrees is predicted for Grafton tonight, while Yamba looks set to escape with a low of 12 degrees.
Weatherzone meteorologist Kim Westcott said the weather change was not a result of the intense low pressure system sweeping the lower half of the nation, but a large high pressure system sitting over the rest of the country, which is expected to bring sunny, cloud-free days.
This will translate to clear nights; great for star-gazing but not so good for trapping heat.
"What we have currently is a system bringing really sunny and settled conditions," she said.
"But because we've got this big high, (Grafton residents) will notice more than one cool morning in the next week and a half," she said.
"It's going to be a bit of a shock to the system for some people, but winter is not really coming yet because the days are still quite warm.
"Maybe we're starting to see autumn."
Over the next week in Grafton, top temperatures are expected to average about 26-27 degrees, while Yamba will be slightly cooler with tops of 24-25.
Ms Westcott said the long-term average May temperature in Grafton was 23 degrees.
Eleven days in, the current average for this month is 28 degrees.
