August 2022 Update SA *Forecast prepared between August 16th-18th 2022 Review: G’Day everyone, the middle of the month is here and that means time for another little update on proceedings. So far, the month has gone to plan with a broad shift in the patterns from the blocking and high pressure of July to more mobile systems and increased moisture out of the NW. But we have only just started, more significant systems are yet to come through either later this month or spring generally once higher Precipitable Water (PWAT) moisture can feed in. The main change has been the Longwave Trough, which has stood up very strongly over the WA longitude, giving them a significant burst of good falls to start August. This large Longwave resulted in a period of windy conditions over SA with N to NW winds over many days, strong and gusty at times with raised dust in very dry parts, in particular on the 2nd ahead of the first sliding front.

Dry and cold was the order of the month, with a number of blocks of frosty nights caused by significant high-pressure systems. As explained in the mid-month update plus subsequent quick update in the past couple of weeks, the main trigger for all of this has been the powerful upstream blocking caused by a large number of East Coast Lows (ECL’s) and general strong mid-latitude cyclones/lows in the Western Pacific. This effectively held up the traffic causing highs to dominate across Australia with fronts squashed down. There was a slight improvement towards the end of the month which was expected with some moisture
