  SA Quick update Upper trough with showers and thunderstorms Feb 28th-Mar 1st 2022 G’Day all, thought I’d whip out a quick little update on things tomorrow, after a fairly quiet spell here we are finally getting a bit of instability (well today we already saw the start over the Lower SE) Meteorological Discussion In short, we will see an upper-level low move up from the SW overnight to be located over the Spencer Gulf by sunrise.
