NSW has not experienced the heaviest rainfall in decades until a night of thunderstorms drenched part of the state with extreme outpour.
Earlier this week, severe heat waves have been prevalent over the atmosphere, yet brought a swift change last night as showers and thunderstorms were experienced in major parts of NSW.
During the afternoon, storms intensified and delivered more than 100mm of rain to several locations overnight.
For instance, the rain gauge at Condobolin received 127mm of rain during the 24 hours to 9 am today – less than one millimetre off the highest daily rainfall ever recorded at the site: a 127.2mm way back January 1976. It was also intensely heftier than an average 46mm for January’s monthly average for the site.
Meanwhile, Cootamundra’s 52mm during the last 24 hours was its highest January daily total in at least 26 years and its highest for any month since 2012. Among other notable records include 87mm at Murrumburrah in the South West Slopes and 56mm at Temora in the Riverina, which was the highest daily rainfall in a decade.
Sadly, it is already forecasted that the rain will persist over western and southern inland regions of NSW as residents are warned of larger and heavier showers to severe storms are underway which will occur over the weekend. This comes with tropical moisture prevailing across the atmosphere of the state.
Due to the surprise of the sudden change, the Bureau of Meteorology’s latest climate outlook for the next three month period revealed above-average wet weather is more likely to happen.
On the other end, daytime temperatures for February to April are likely to be warmer than average over Tasmania and around much of the Australian coastline.
As per the BOM, this wet weather is a byproduct of La Niña as it remains active in the tropical Pacific. The season has likely reached its ultimate strength yet is expected to continue to influence Australian rainfall patterns until at least early autumn.
