It's an extremely chilly Wednesday in Adelaide by late October standards with the mercury cautiously edging up to a predicted top of just 15°C, but unfortunately there's not much rain accompanying the unseasonable cold.

"I can confirm that a hoodie wasn't enough for my morning coffee run," Adelaide-based meteorologist Stephen King said around 11 am local time, when the city's apparent or "feels like" temp was just 7.7°C.

You can see the surge of cold air pushing northwards over southern parts of South Australia in the three-hour loop to 9:10 am morning.

While light showers are occurring across southern SA from about the Yorke Peninsula eastwards, there's not enough moisture with this system to generate significant rainfall.

• Overnight, falls were only in the vicinity of a millimetre or two at most weather stations in the southeast, with similar readings expected today.
• Some spots have missed out entirely on rain in this system as at 10:30 am local time, including Adelaide's "official" weather station at West Terrace/ngayirdapira and most other nearby stations, which is bad news for the city’s parched parks and gardens.

Take a look at the 12-month rainfall graph for Adelaide.

After a relatively wet first half of the year, the last four months have all had significantly below-average rainfall – and there's almost no rain expected between now and the end of the month.

Further afield in Victoria, the cold air has also arrived this Wednesday, with Melbourne likely to reach just 14°C - its coldest day since October 4.

Like the southeast of SA, southern and central Victoria likely won't see big rainfall totals from this event.

This cold airmass is well and truly cold enough for snow in the mountains with an 11 am temperature of -1.4°C at kunanyi/Mt Wellington above Hobart and -1.8°C at Mt Buller, northeast of Melbourne.

But again, lack of significant moisture means that Victoria has so far dodged the flakes and it’s completely sunny in the Snowy Mountains of NSW.

However snow has fallen in parts of Tasmania, as evidenced by the live cam at Mt Mawson, about two hours west of Hobart.
