Southern parts of Western Australia shivered through chilly morning beneath settled skies today.
A broad high pressure ridge residing over southern parts of WA yesterday gave rise to some frigid temperatures in the early hours of this morning. Clear skies and cool temperatures in the wake of Monday's cold front allowed the mercury to fall, particularly about inland areas where winds were calm.
Pearce RAAF Base dropped to almost six degrees below the July average with a minimum of three degrees. It was a similar story at Perth Airport where temperatures dropped five degrees below average.
In contrast to these crisp temperatures, a broad band of cloud extending from the Pilbara to the Goldfields with an upper level trough kept minimum temperatures higher than usual.
Meekatharra enjoyed their warmest night in more than five weeks with a minimum of 11 degrees. Similarly, Paraburdoo's minimum was 4 degrees above average which also made it their warmest night since the same event.
Interestingly, Paraburdoo has only seen one other above average minimum temperature so far this month which was only 0.4 degrees warmer than the July mean.
Leading into the weekend this upper level trough is expected to deepen and distribute moisture over Pilbara and Northern Interior districts. A similar northwest cloud band delivered in excess of 200mm over the Kimberley region last weekend.
This system isn't looking quite as moisture laden however, isolated falls up to 50mm are a chance about the Pilbara region tomorrow.
