On a day when Australia's parliamentary stability has increased, the stability of the nation's weather is on the decrease, proving that the two are not linked, at least not proportionally. A cluster of storms has been raging over the southeast corner over WA, gradually moving into SA. Cloud from these showers and thunderstorms has been caught in strong winds aloft and spread over SA like a blanket. The widespread cloud has delivered a remarkable outcome: a cold September day for inland SA. Ernabella barely saw the mercury move as showers kicked in from mid-morning. All in all about 16 millimetres has been recorded, their wettest day since April and the third wettest day this year. Ernabella's maximum was also quite notable. Topping at only 14 degrees, this was their coldest September day in 13 years of records. Coober Pedy, in the heart of the state, was also quite cool for this time of year. The temperature there only reached 17, the coolest September day in five years. Tomorrow, the cloud continues to spread east, keeping temperatures unusually cool for this time of year. The unstable conditions will also persist, bringing a few storms to eastern SA.
