Forecast issued at 4:30 am EST on Thursday 28 July 2016.
A high over South Australia is extending a ridge into New South Wales in the wake of a series of cold fronts. This high will be the dominant synoptic feature in the region during the next few days, moving slowly across southeast Australia and blocking the progress of approaching fronts. The stability of this system should promote fine weather and increasing daytime temperatures in most districts, although mornings will remain cool. Later on the weekend the high is forecast to weaken as it nears the Tasman Sea, allowing the next significant cold front to move through New South Wales early in the new week.
Forecast for the rest of Thursday
A shower or two about the southwest slopes and adjacent ranges, with snow on the Alps above 1500 metres. Fine and mostly sunny elsewhere. Morning frost patches inland, more widespread over the tablelands. Patchy morning fog about the tablelands. West to southwesterly winds, tending light across the north.
Friday 29 July
A shower or two about the southwest slopes and adjacent ranges, more likely in Alpine areas and falling as snow above 1600 metres. Fine and mostly sunny elsewhere. Morning frost over the slopes and ranges. West to southwesterly winds across the south, tending light in the north.

Fine and mostly sunny, apart from the chance of a shower about the southern Alps and surrounds. Early fog and frost patches in the east, mainly about the ranges. Light winds, tending north to northwesterly across the south.
