You can take off a layer of clothing before going to bed this weekend, with the mercury set to sky rocket to a sweat inducing -1 degree Celsius.
OK it may not be the summer warmth we’ve been dreaming of but it’s certainly an improvement from the Antarctic cold snap that has rendered our open fires and electric blankets useless.
“Saturday, Sunday, Monday and Tuesday were the four coldest (consecutive) nights since July 1971,” a spokesman forthe Bureau of Meteorology (BOM) revealed. An average low of -5 hit the Yass Valley during that period and it is believed to be the result of a strong cold front caused by the cold air coming from Antarctica.
“We’ve only seen this three timesin the last 50 years in terms of consecutive nights,” the spokesman said.
Because of the clear nights, light winds and low humidity, the frosty mornings will greet us for a while longer but we’reslowly coming out the other side.
“Very gradually…generally July is the coldest month of the year and we can see that the weekend is expected to be -1 so the cold front is easing,” he said.
Essential Energy recorded a noticeable increase in consumption during the last week.
“The demand for power for the Yass and Gunning areas has trended upwards in the past week with an average increase ofaround eight per cent for the five days from August 2-6 compared to the previous week (July 26-30),” said Simone Reading, South Eastern Community Relations manager.
“Electricity demand typically increases during periods of extreme weather. For example, in the early morning hours ofWednesday August 6 customers across Yass and Gunning drew around 27 per cent more power than they did at the same time the previous week,” she said.
Wednesday morning’s temperature bottomed out at a bone chilling -5.5 but the day time temperature was a pleasant 13degrees (the average for the week).
More worrying for farmers than the cold snap is the forecasted lack of spring rain.
“The eastern side of Australia is looking at above average temperatures and below average rainfall, that’s the negative,”the BOM spokesman said.
“The positive is that the Indian Ocean is in a favourable phase for above average spring rainfall. So the west and centralAustralia will see lots of rain, and sometimes when that happens, it can get all the way over to the south-east.
“So we’re looking to the Indian Ocean rather than the Pacific.”
He explained that our best chance of substantial rain is in the next three months.
“Certainly the best chance of rain is in spring and a lot depends on whether we get El Nino or not.”
According to BOM there is a 50 per cent chance that we will receive a hot and dry summer (El Nino) and that is the most
likely outcome with La Nina and Neutral making up the other 50 per cent.
