Upper Analysis Charts - 850hPa

850hPa chart: This analysis chart provides temperatures at 1500m ASL (850hPa) across the Australian region. The coldest air is shown from purple (in the south) through blue and green, and then warmer air is shown in yellow and oranges, and then purple again over the continent (as the hottest). Updated twice a day showing conditions at 0Z & 12Z.

VICTORIAN ALPINE SNOW POTENTIAL DISCUSSION 3/7/08 1900HRS AEST

OVERVIEW: After the best snowfalls for the season so far earlier this week the snow potential outlook looks a little difficult to analyse for the coming 7 days or so...

A large high pressure system will move into southeast Australia Friday with light winds and sunny days, expect overnight frost especially Saturday morning, the high pressure cell moves east of Victoria through Saturday allowing a broad trough over WA and SA to encroach onto Victoria later Sunday and into Monday, preceding this trough a northeast/northerly airstream will bring rather milder air into Victoria from Sunday to Monday.

An upper cold pool is associated with this trough and appears will manifest itself as a surface depression over the Murray region of SA Sunday and Monday before drifting across northern Victoria Monday and Tuesday. Rain areas will develop across the alpine areas of Victoria from Sunday into Monday and most likely hang around Tuesday as well, at present freezing levels appear near 1800m to 2200m ahead of this trough so at this stage mainly rain with a little wet snow above 1800M is anticipated Sunday and Monday.

On Tuesday the upper cold pool will bring the snow line nearer 1500/1700M so a reasonable chance of snowfalls getting down to intermediate and upper slopes (will keep an eye on the cold pool) if this occurs a reasonable chance of 10 or 20cm falls on the higher ridges Tuesday/Wednesday of next week.

After Wednesday of next week a ridge of high pressure advances east into southeast Australia with snow/precipitation tapering off to a few flurries and freezing drizzle for Thursday.

regards from Aussky...watch for more detailed updates from Sunday....

500hPa chart: The contours are the 18,500' (500 hPa) height field which indicates air flow at that level as well as the overall thickness of the atmosphere between the surface and the 500hPa pressure. The 540 line is marked in black. Updated daily at 0Z & 12Z.
