"Sydney, Australia has just shivered through its coldest July day in a decade after maximum temperatures struggled to just 12.1C (53.8F) on Friday afternoon.

That Friday high of 12.1C (53.8F) was Sydney’s coldest July maximum since 2011

... Sydney’s record cold comes after a particularly icy week for the state of NSW, as well as for the entire Australian continent as whole

— every state and territory managed to register temperatures cold enough for frost, and all but one saw the mercury plunge below -2C (28.4F), reports 9news.com.au.

The reason for the frigid mornings was string of high pressure systems kicked-up from the polar regions.

These caused a combination of clear skies, light winds and extremely cold, dry air — the ideal ingredients for frost-producing lows at this time of year.

Perisher in the NSW snowy mountains recorded Australia’s first -10C (14F) of the year, while Alice Springs woke to sub-zero temperatures twice in one week, a very rare occurrence.

Further chills are to be forecast across the Australian continent over the weekend.


Upper Michigan suffers a rare Summer Freeze

Several locations in Upper Michigan suffered a rare summer freeze on Friday, July 9.

The mercury struggled to 31F (-0.6C) yesterday morning at Baraga Plains, Doe Lake and Stonington “in the 2nd week of July!”, exclaimed a recent woodtv.com article.

With dry air (low dewpoint) and a polar breeze, the temperature managed to plummet across the UP, even with the relatively short nights of mid-summer.

For many locales, the overnight drop was stark — in Stonington, for example, the high on Thursday touched 74F (23.3C),

but that 31F (-0.6C) low logged by Friday morning meant the city suffered a whopping 43F (23.9C) temperature drop

— another example of the increased swings between extremes we experience during times of low solar activity.

While not a freeze, the mercury did dip into the 30s across a significant portion of the U.P.

Low temperatures included 38F at Ironwood and 39F at Marquette (airport) — all record lows for the time of year."
