High pressure system ‘blocking’ will bring new burst of cold weather

Millions of Australians will be wearing hats and woolen clothing this week as a very cold air mass sweeps across much of the country.

In many parts of southeast Australia, high and low temperatures over the next few days will be well below average.

The cause is high pressure crossing the Great Australian Bight following a cold front that swept through the southeastern regions over the weekend.

While high pressure is common after a cold front, this particular system will stall starting early tomorrow and become what forecasters call a “locking preview.”

It will bring a prolonged run of sunny days but cold, frosty nights across much of Tasmania and large parts of Victoria and southern New South Wales.

Temperatures in Launceston are forecast to drop below zero for the next seven consecutive mornings.

A wax depiction of Abraham Lincoln has fallen victim to a heat wave in Washington, D.C. The sculpture, by Virginia-based artist Sandy Williams IV, was placed outside Garrison Elementary School as part of a series of wax memorials. The temperatures melted the sculpture of the country's 16th president. The school is taking the disfigured head to be repaired, according to local news outlet WJLA.

In Queensland and northern New South Wales, high pressure is bringing persistent south-easterly winds to the coast, increasing the chance of showers each day as well as established ocean swells.

For the rest of northern Australia, higher temperatures to the south will increase winds, leading to warmer days. The increased winds also increase fire danger at the start of the bushfire season in northern Australia.

For parts of South Australia and Western Australia, the high means this week’s low pressure systems and cold fronts will be more likely to bring rain for longer periods than normal.
