MONTHLY WEATHER REVIEW - ARMIDALE NSW
June 2012 was cool, dry and partly cloudy.
Although there were a number of light falls throughout the month, the rain total of 30.8 mm was well below the average. The highest daily fall was just 6.0 mm on the 27th.
Temperatures were mostly close to normal with three exceptions described below.
Prevailing winds were light to moderate westerlies.
5th - An upper level pool of cold air passed across northern New South Wales. This system, combined with moist south-westerly winds generated by an intense low pressure system in the Tasman Sea, produced very cold air over the Northern Tablelands, so showers falling above about 1300 metres arrived on the ground as snow. Armidale missed out, but the Guyra/Black Mountain/Ben Lomond areas all received light non-settling snowfalls. Armidale’s maximum temperature was 6.5C, the coldest day temperature since 11th August 2008 (6.5C).
24th & 25th - The minimum temperatures of -8.8C and -9.0C respectively were the lowest temperatures recorded in Armidale since 30th June 2010. Clear skies, combined with cold dry air following the passage of a cold front on the 22nd, resulted in the very chilly mornings. Temperatures of -8.0C or lower occur on average of two days per year.
