Yesterday was Adelaide's coldest day of the year so far, but even colder weather is on its way.
Thick cloud and showers combined with a lingering cold airmass brought one of the chilliest June days in recent history on Tuesday. Leigh Creek only warmed to 10.4 degrees, and Roxby Downs to a mere 13.6 degrees, experiencing their coldest June day in 27 and 12 years, respectively. Wommera (13.2 degrees) had its coldest June day in five years while Tarcoola (14.3 degrees) and Ceduna (14.7 degrees) had their coldest June day in four years.
Adelaide reached 14.2 degrees yesterday, the coldest day of the year so far; but there are colder days to come with a powerful cold front set to arrive on Thursday.
This front is expected to bring 10-20mm of rain to coastal areas, with 2-6mm for inland areas. The heaviest rain is expected to fall in the area around Mount Gambier, with 30-50mm possible. Snow is a chance along the Mount Lofty Ranges, but falls are expected to be fairly light.
Winds will become very gusty from the west-southwest, reaching 80 km/h for exposed coastal areas during Thursday afternoon. The ocean will also become very rough as a six metre swell hits just off the South Central and Lower South East coasts. Large swell coupled with abnormally high tides plus the addition of heavy rain have the potential to cause some minor flooding as well as some areas of coastal erosion.
Another weaker front is set to move through early on Sunday continuing the run of colder days, with the temperature in Adelaide unlikely to rise above 14 degrees from Friday until Sunday.
A high pressure system will build in the wake of the second front allowing showers to clear and daytime temperatures to begin to warm up. Overnight temperatures will cool below ten degrees until the middle of next week.
