It was a cold night across northern NSW, with the Hunter Valley, Northern Tablelands and the Northwest Slopes and Plains experiencing particularly cold and frosty conditions.
Thursday in Cessnock saw a much warmer than average morning where the minimum temperature was 6 degrees above average, while the next day saw a minimum temperature 13 degrees cooler at -2.7 degrees. This was Cessnock's coldest night in 2 years and 7 degrees below the August average. Further north, Tocal recorded its coldest August night since 2008 dropping down to 0.9 degrees.
The Northern Tablelands and the Northwest Slopes and Plains weren't spared from the cold either. Barraba saw its coldest August night in 5 years reaching a low of -6 degrees while Glen Innes Airport saw a crisp low of -8.7 degrees, its coldest temperature this year so far.
Over the next few days, the Hunter Valley and Northern Tablelands will see warmer overnight temperatures due to a trough moving over the region bringing with it cloud and wind.
A cold front will move in to the area on Monday evening bringing with it a much colder airmass. A high will then follow the front, causing clear skies and light winds. This combination will allow for a return of cold and frosty mornings from Tuesday which is likely to persist until later in the week.
