INDO/AUSTRAL/PACIFIC TROPICAL & CONVECTIVE WEATHER DISCUSSION

0800HRS 30/04/2008 AEST VIC

DISCUSSION: Large scale convection remains over parts of the Bay of Bengal and also spreads into central Burma/western Thailand. isolated convection appears over the Indonesian islands except southeast Borneo where large scale multicell groups appear. A marked split phase appears across the western Pacific with a northern hemisphere alignment running from near 136 east/3 to 10 north to east of the dateline mainly multicell groups and occasional merging larger scale convection, over the southern hemisphere a band of showers and storms trail from southeastern Borneo to Papua then terminating near the Solomon's. A mid latitude trough digs into the tropics from the southeast of Papua to south of Fiji before merging with an active trough passing through New Zealand.

VICTORIAN ALPINE SNOW POTENTIAL DISCUSSION 6/05/08 0600HRS AEST

OVERVIEW: A weak 'westerly' airstream affects the Alpine areas of Victoria this week alternating between northwest and southwest, indications show a gradually cooling trend through the week as a high pressure system strengthens southwest of Adelaide from Wednesday, meanwhile a serries of weakish cold fronts will pass over the alpine areas with showery spells/drizzle and plenty of highland fog, the cooling trend will bring sleet and snow showers initially to the higher peaks from Tuesday night ( above 1600M) then gradually descending to near 1400/1500M after Wednesday...mainly brief and light falls. The high pressure system moves in for the weekend with more settled weather and cold frosty nights. The next trough appears early next week with freshening north winds and showers ahead of another colder trend after next Tuesday.
