Wednesday: Moderate SW winds will persist today bringing cold temperatures to the resorts with freezing levels generally below 1000m. Snow showers will be infrequent during the day.
Snow: 2-5cm in the west, mainly clear in the east.
Thursday: Cold and cloudy at first as the SW air stream persists. Winds will be moderate around 30-40km/h. A high pressure ridge should move in by Thursday bringing the afternoon which should see skies clear.
Friday: As the country remains under high pressure skies should clear. Winds will be light and variable. My pick of the week to go skiing.
Saturday: Very similar to Friday as the high pressure system remains stationary. Another great day
Sunday: Fine at first however cloud will begin building by late afternoon as a low pressure system approaches from the Tasman Sea. Should be a good day skiing as most of the cloud looks like it will form late into the afternoon/night.
Monday: A front looks like it will approach from the west. Winds look like they will begin to strengthen from the NE, with possible wind gusts up to 100km/h. Freezing levels look to warm for snow, and rain is possible late in the afternoon. Not a fantastic day for skiing.
Tuesday: The weather models are a in a bit of disagreement however it looks like there will be a period of rain before a cold front crosses, winds turn south-west and snow begins to fall. A little too early to determine amounts.
Looking Ahead: The great snowfalls of yesterday and Monday were thanks to a surge in an upper level weather pattern known as the "jet stream." The best chance of a decent front and low occurs when this pattern is wavy and active. Looking ahead it looks like it may become active again next Wednesday and Thursday. I will be keeping an eye out on the charts and keep you posted about these systems as they develop.-NZsnowforecast
