State hit by overnight cold snap
IF you felt a bit chilly on last night, you weren't alone with the state experiencing a near record-breaking overnight cold snap.
Senior Weather Channel Meteorologist Tom Saunders said minimum recorded temperatures plummeted to as low as minus 10 degrees Celsius in some parts of the state.
Grafton recorded an overnight minimum of 2.5 degrees Celsius while conditions were slightly warmer overnight, Yamba still dropped to a brisk 6.5 degrees Celsius.
Mr Saunders said the sub-zero temperatures also caused frost areas to extend across every inland district of the state.
The New England Highway was closed to all traffic at about 3am on this morning for safety reasons after large areas of black ice formed on the busy road.
"The minimums were only a few degrees off all-time records due to the perfect combination of cold, dry southerly winds and clear skies," Mr Saunders said.
"Thankfully both cloud and wind will increase during Thursday, allowing slightly milder temperatures for the rest of the week into the weekend."
