Sub-zero South Australian mornings

Guy Dixon, Saturday August 2, 2014 - 12:16 EST

Residents of South Australia felt the chill of a cool morning today in the wake of a strong cold front which passed overhead in the past 48 hours.

Following this vigorous front, a high pressure ridge promptly took hold allowing winds to settle and skies to clear. However, a broad pool of cold air is continuing to linger over southern parts of the nation, resulting in sub-zero minimum temperatures.

Some of the most significant and widespread minima were experienced about South Australia's Mid North, Flinders and North East Pastoral districts where Hawker felt its chilliest August morning in 35 years worth of records. The mercury fell to just minus five overnight, a huge nine degrees below average. This was a stark contrast for residents who felt a minimum of 6 degrees the previous night, an 11 degree discrepancy in the 24 hours period.

Clare also shivered through a cool night with temperatures dropping seven degrees below average to a minimum of minus two. This made it the coolest August night since 1994. Yunta was one of the coolest locations state wide with a low of minus five, more than nine degrees below the August average.

The story continued closer to the coast where Minalton, despite not being as cool as inland regions felt their coolest night for any month since 2008 at 0.7 degrees.

A broad, slow moving high pressure system will maintain clear skies and light winds allowing the freezing mornings to continue throughout the next week. Frost and patchy fog about parts of South Australia will become a high likelihood under these settled skies.
