A strong\u00a0high\u00a0pressure\u00a0system has delivered some of the coldest weather in years across parts of Australia, with many residents reaching for an extra blanket overnight as freezing mornings gripped the southeast,\u00a0as well as\u00a0unusually chilly conditions extended far north into Western Australia and the Northern Territory under a very dry atmosphere.\u00a0<\/p>\n

Some locations recorded their coldest morning in years, including:\u00a0<\/p>\n


\nBraidwood, NSW: -6.1\u00b0C (coldest in 3 years),\u00a0
\nDelegate, NSW: -6.1\u00b0C (nearly 3\u00a0years),\u00a0
\nDum In\u00a0Mirrie, NT: 12.8\u00b0C (2 years),\u00a0
\nCape\u00a0Fourcroy, NT: 13.3\u00b0C (2 years),\u00a0
\nKalumburu, WA: 8.3\u00b0C (2 years),\u00a0
\nStrathalbyn, SA: 0.6\u00b0C (2 years).\u00a0 <\/p>\n

The\u00a0cold weather\u00a0has been caused by a strong\u00a0high pressure\u00a0system sitting over southeastern Australia. High pressure overhead brings clear skies and light winds, allowing heat at the surface to effectively escape into space overnight. Normally, clouds act like a blanket by trapping some of the Earth’s warmth, but with little cloud around, temperatures can fall rapidly after sunset.\u00a0<\/p>\n

High pressure systems also\u00a0provide ideal conditions for fog to form overnight. While morning fog usually rises and clears after sunrise, parts of inland Victoria remained shrouded in fog well into the afternoon yesterday, with similarly persistent fog\u00a0likely again\u00a0today. The fog blocked much of the sun’s warmth, keeping temperatures low throughout the day.\u00a0<\/p>\n

As a result, several Victorian locations recorded their coldest July day in decades, including:<\/p>\n


\nStawell: 6.9\u00b0C (coldest\u00a0day on record, 30 years)
\nLongerenong: 8.1\u00b0C (24 years),
\nHorsham: 8.1\u00b0C (22 years),
\nEdenhope: 9.1\u00b0C (10 years),
\nWalpeup: 9.0\u00b0C (6 years),
\nCharlton: 8.2\u00b0C (6 years),
\nHopetoun Airport: 9.4\u00b0C (6 years),
\nSwan Hill Aero: 8.9\u00b0C (6 years),
\nWarracknabeal Airport: 7.4\u00b0C (6 years). <\/p>\n

Fog and low cloud\u00a0is\u00a0once again shielding much of northern Victoria from the sun this Sunday, bringing a second bitterly\u00a0cold day\u00a0in a row.\u00a0The\u00a0high\u00a0pressure\u00a0system is expected to keep conditions mostly dry and settled across southeastern Australia over the coming days, with light winds bringing further cold mornings and allowing fog to form and linger in some areas.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"A strong\u00a0high\u00a0pressure\u00a0system has delivered some of the coldest weather in years across parts of Australia, with many residents…\n","protected":false},"author":2,"featured_media":809591,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[64,63,44],"class_list":["post-809590","post","type-post","status-publish","format-standard","has-post-thumbnail","category-australia","tag-au","tag-australia","tag-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/809590","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=809590"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/809590\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/809591"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=809590"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=809590"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=809590"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
