DISCUSSION: As a low-pressure continues to move slowly off to the south and southeast later today, the threat for accumulating snowfall across eastern sections of Queensland as well as eastern sections of New South Wales. As seen in the radar graphic included below courtesy of the Higgins Storm Chasing group, there is light to moderate snowfall occurring across New South Wales currently. This light to moderate snowfall is the result of persistent warm-air advection emerging off of the Western Tasman Sea effectively slides over the colder air located across Southeastern Australia. This trend for persistent snowfall is expected to persist for at least the next 6 to 12 hours before the associated low-pressure system begins to slowly pull out of the regions as it heads further southeast with time!

MIXED BAG EVENT PROJECTED FOR EASTERN AUSTRALIA! (credit: Melbourne Storm Chasers)
DISCUSSION: As a complex forecast situation evolves during the course of this week, there are expectations for a complex low-pressure system to slowly develop over Central to Eastern Australia before impacting sections of East-Central and Southeastern Australia. As this process gets underway, much colder air filtering into the aforementioned regions behind the passage of a cold front will help to support the generation of hail in association with intense thunderstorm (i.e., located primarily across the Southeast parts of the country) while snow and sleet predominantly falls across the higher terrain of regions located closer to Central and East-Central Australia! It is important to bear in mind that while across much of the Northern Hemisphere we are entering the beginning of the Summer months, it is the beginning of the Winter season across many parts of the Southern Hemisphere including across many parts of Australia as detailed further in the post below courtesy of the Melbourne Storm Chasers staff!

HEAVY RAINFALL EXPECTED ACROSS PARTS OF QUEENSLAND! (credit: Higgins Storm Chasing)
DISCUSSION: As a slow-moving low-pressure system gradually makes its way eastward across Northern Australia and onward towards Northern and Eastern Queensland, Australia there will be an increasing threat for heavy rainfall and widespread flooding. This flooding threat is expected as a consequence of a slow-moving low-pressure system which will become stationary along the Gold Coast region of Australia. Therefore, as the week comes to a close and next weekend unfolds, the threat for heavier rainfall will increase as also reflected by the information in the graphic below courtesy of the Higgins Storm Chasing group!

ACTIVE WEATHER IMPACTING THE GOLD COAST OF AUSTRALIA! (credit: Higgins Storm Chasing)
DISCUSSION: As a weak low-pressure system slowing moving south continues to induce strong lifting of warm/moist air along the Gold Coast of Australia during this morning and on into this afternoon, strong to severe storms will continue slowly moving south with time! As a result, strongs winds and heavy rainfall can certainly continue to be expected as this persistent convection continues to slowly head south! If you are currently living or visiting this part of Australia and you encounter flooded roadways, do the same thing the National Weather Service office promotes over in the United States "Turn Around and Don't Drown!"

CLASSIC ALTOCUMULUS UNDULATUS IN TASMANIA A FEW DAYS AGO! (credit: Bureau of Meteorology)
DISCUSSION: As of just a few days ago, this was the "post-card" like scenery captured by Toby's View Photography in Tasmania (located off the southeast coast of Australia). Note how you can identify the alternating rows of "wobbling" clouds; indicating the presence of gravity wave-like features which were causing the undulation in the clouds streets which formed in the vicinity of the coastline. This cloud cover is typically a result of a passing cold front which leaves behind residual moisture in the atmosphere and in the presence of a gravity wave which is essentially an oscillating gravitational force which forces clouds to develop at the base of each gravitational wave where moisture condenses the most!
