A series of cold fronts are expected to sweep through Victoria and Southern NSW across the next week, with the strongest coming through on Tuesday and others on Friday into Saturday. On Tuesday, a vigorous cold front is likely to move through South-Eastern Australia producing widespread showers and rain across Victoria and Southern NSW. While damaging to destructive winds (more than 125km/h) and heavy rainfall of 50-75mm (possibly higher) are expected over the Alpine region, and 5-15mm across VIC, conditions are expected to be far too warm for snow to occur and this may see a lot of the snow melting. Its on Wednesday, Thursday and Friday when conditions ramp up and any melted snow is restored.
Forecast Rainfall on Tuesday via BSCH / OCF. Totals are conservative and may be doubled.
During Wednesday evening / night, an upper level trough being dragged behind the Tuesday cold front is expected to start impacting Victoria and Southern NSW where snow is likely to originally fall down to around 1400m. Only light falls are expected on Wednesday due to the timing of the colder air. On Thursday and into Friday, the coldest air is expected over the region and combine with high moisture levels to produce snow down to 1000m and possibly down to 800m. Damaging winds will also add to the equation creating hazardous blizzard conditions at times. Falls of 40-60cm are expected over Thursday and Friday alone.
As the second cold front moves through later on Friday and lingers into Saturday, it should continue to top up snow totals with light constant falls into the weekend where another 10cm+ is likely and possibly higher. By Sunday night, up to 80cm may have fallen over the Snowy’s giving a 14-18 day total of more than 200cm!
