New mini convergence zoneJake Smethurst wrote: ↑Tue Oct 16, 2018 6:59 pm Some good rain here at the moment, though only up to 3mm so far. Hopefully a bit more to come over the next hour or so with some heavier stuff to the north (slowly edging eastwards). Still unstable to the west of this band with fresh storms developing east of Port Campbell and northwest of Ballarat (a little line potentially forming).
Generally speaking Wilko, where more air is entering an area than actually leaving it (at a specific level). It causes vertical motion, typically upward forcing if it's lower-level convergence (the air has to go/leave somewhere). And if we have upwards forcing we can get development of showers and storms if other conditions are present. If you look at the wind obs, you can see the northeasterly winds meeting the northwesterly winds - a zone of sorts. Hopefully that explains it a little … and others feel free to add or explain better
You’re on track to be the one spot in Vic to get above average this month (though hopefully we all get there). Lucky for your area your MTD must be near 80mm now27mm in my gauge, a lovely rainy spring day. Very happy.
