Wintry end to the week in NSW

Ben Domensino, Wednesday July 1, 2020 - 12:09 AEST

Rain and snow will return to parts of NSW during the next few days as a pair of cold fronts pass over southeastern Australia.

The first front will cross the state between Wednesday night and Thursday, causing a burst of wind and showers. The strongest winds will occur on the central and southern ranges, with damaging winds possible in some exposed areas. At midday on Wednesday, a severe weather warning was in place for the damaging winds above 1600 metres elevation in the southern ranges.

Rain from this first front will be mostly confined to the southern and central inland, on and west of the ranges. These showers will fall as snow in the alps and could reach down to about 1300 metres elevation by Thursday night.

Another weaker front will follow on Friday, bringing a second surge of cold air and showers during Friday and Saturday.

On Friday, a few showers will develop about the northern slopes and ranges at the leading edge of the approaching cold air mass. Parts of the Northern Tablelands and Northwest Slopes could see 5-10mm. Some of these showers could also affect the north coast, although falls will be patchy and light east of the divide.

Further south, another round of showers will affect the southern and central inland of NSW between Friday afternoon and Saturday morning. These showers could fall as snow down to about 1000 metres in the southern ranges and 1,200 metres in central NSW.

All up, most areas of NSW will only see light falls from these two fronts, with many areas, unfortunately, missing out this time around. The heaviest falls will occur on and west of the southern ranges, where some places could see more than 20mm by Sunday.

This pair of fronts will also deliver some much needed snow in the alps, with around 10-20cm expected to accumulate by the end of the weekend. This will help improve the natural snow base, which was sitting only 24cm deep at Spencers Creek in the middle of last week.

Winter is Coming: Chilly day for Sydney, rain pelts eastern seaboard

17:22 AEST Just as we forecast yesterday, a coastal trough has deepened along the NSW and southeast Qld coasts as a low in the Coral Sea continues to inch closer to Qld. The trough has brought some interesting weather to NSW in the past 36 hours or so, particularly along the coastal fringe, giving those New South Welshmen a “Stark” Game of Thrones reminder: winter is coming.
