As expected this week, beyond the wintry shift over the coming 24-48hrs for large parts of the nation's south and east, the weather will likely turn back to more seasonal values by Friday and into the weekend, the seasonal weather is anticipated post the last front over the southeast before a spell of above average temperatures.
Moisture is expected to return from the weekend over the west of the nation and across the eastern seaboard with troughs likely to be in phase over these areas, lifting rainfall chances for the end of the month into October.
