Residents in WA's southwest have shivered through their coldest July night in many years, but warmer nights are just around the corner.
Across the region the mercury dropped between five and seven degrees below average in the early hours of Sunday morning. Inland areas were the coldest, with frost affecting many parts.
The residents of Manjimup would have been reaching for their ugg boots. It was their coldest July night in eight years, with an overnight minimum of only one degree.
For Katanning and Wandering in the Great Southern, it was the coldest July night since 2006, with one and minus three degrees respectively.
The mercury also fell to minus three at Cunderdin Airfield, nearly eight below average and their coldest July night in three years. It was the same story for Busselton, where it dropped to just one degree.
Elsewhere, it was the coldest night of the year so far for Salmon Gums, Witchcliffe, Bridgetown and Norseman.
Another frigid evening is on the way, thanks to a high pressure ridge lingering over the region. This system is bringing clear skies and light winds, which are combining with a cold airmass to bring the teeth-chattering nights.
Warmer nights will kick-in from Tuesday, as an approaching cold front brings cloud, showers and gusty winds. This will prevent cold air from settling near the ground at night and most parts will be at least five degrees warmer for several days, with more wet weather expected later in the week.
