Jane Bunn's Snow Forecast Discussion
Updated: Thursday morning.
A trough is weakening off the NSW coast, while a high pressure system settles in over the southern Tasman Sea. This makes it warm in northerly winds.
THURSDAY: All dry. Areas of sunshine and areas of cloud. (Some cloud from the trough to the east, other cloud over northern slopes, thanks to northerly winds coming up the slope).
FRIDAY: All dry. Areas of sunshine and areas of cloud.
A cold front arrives over the alps on Saturday, but the cold air lags behind. Expect a period of rain, finally changing to snow later.
SATURDAY: Persistent rain for much of the time. [10 to 20 mm of rain]. Changing to snow in the evening.
0 to 2 cm of snow on Saturday night, lowering through alpine elevations.
Another cold front moves through on Sunday into Monday. This precipitation is lighter and patchier - so its a fight between the cold air from the front, mixing with warm sunshine. So it may fall as snow at times, and rain at times, and be quite variable.
SUNDAY and MONDAY: A mix of sun and cloud, with snow and rain showers.
2 to 5 cm of snow, falling down to 1200m at times.
High pressure extends a ridge back over the alps on Tuesday and stays there for much of the week. Weak fronts may pass to the south.
TUESDAY, WEDNESDAY and THURSDAY: All dry. A mix of sun and cloud.
