Cooling signifies turn of the season

Guy Dixon, Wednesday March 25, 2015 - 12:29 AEDT

Following a noticeably warm beginning of the season, much of inland New South Wales is facing a spell of cooler temperatures.

A few strong cold fronts this week have drawn colder air over much of the state, replacing a persistent warm airmass which has been lingering due to regular low pressure troughs.

In comparison to long-term averages, the warmest places this month have been concentrated across the North West and Central West.

Maximum temperatures have been trending more than four degrees above average this month in places such as Brewarrina, Walgett, Dubbo and Trangie. Minimum temperatures have also been noticeably warm with Brewarrina and Bourke about three degrees above average.

Since Thursday last week, three significant cold fronts have crossed southeastern Australia, leading to distinct cooling and the first prolonged cooling event of the season. The greatest contrast will be felt in the early mornings where minimum temperatures are likely to be as much as 10 degrees colder than average and as much as 15 degrees cooler than earlier in the month.

Leading into the weekend, many inland areas, including Albury and Cobar are likely to have their coldest March nights in seven years. Broken Hill and Menindee may experience their coldest March night in 20 years.

The troughs which were responsible for the warm conditions earlier this month also produced regular showers and thunderstorms in the north. However, only pockets, including Narrabri, Tamworth and Coffs Harbour have gained more than their monthly average rainfall.

The rest of the state has been drier than average this month and unfortunately the cooler air in the week ahead will also lack moisture and therefore rainfall will mostly be confined to the northeast.
