Weekend change for South Australia

Ben Domensino, Friday October 14, 2016 - 16:00 AEDT

Adelaide will have a weekend of two halves as hot and windy conditions on Saturday gives way to cold and showery weather on Sunday.

Southern parts of Australia can experience large shifts in temperature at this time of year as cold fronts sweep from west to east. These changes can cause the mercury to plummet by more than 20 degrees in under an hour.

One of these fronts is scheduled to cross South Australia in the next 48 hours, reaching Adelaide smack bang in the middle of the weekend.

Hot and gusty northerly winds on Saturday will push the mercury up to 29 degrees in the capital and close to 40 degrees in the state's west. It is forecast to be the hottest day since April for Adelaide (29C), March for Cleve (32C), Wudinna (34C) and Elliston (34C) and since February for Ceduna (37C).

A cool southwesterly change will move over the west coast on Saturday afternoon and reach central areas, including Adelaide, during the evening. Most other areas east of Adelaide will see the change on Sunday morning.

Temperatures behind the change will be 10-20 degrees cooler for some areas. Ceduna is expected to drop from 37 degrees on Saturday to 18 degrees on Sunday, while Adelaide is forecast to drop from 29 to 17 degrees.

A band of rain will develop behind the wind change, exacerbating the contrast in conditions across the state.

Rain will affect southern districts from Sunday morning and eastern areas into the afternoon, with more isolated showers, isolated thunderstorms and areas of small hail continuing across the agricultural areas throughout the day.

Temperatures will remain cool in Adelaide during the first half of next week, with help from another cold front on Monday night.
