Agreeing re upcoming severe event ( see map below)
Here are the surface gradient wind streams
showing a line of convergence for a cooler moist boundary from the very large low
interacting with warm/hot dry air from interior ( depending on location) drawn southward across SA and VIC by the large Tasman high
drawing heat across SA and VIC on Wednesday/Thursday
The map from the link below shows the worst scenario by ACCESS interactive
on Thursday morning at 4 am in the west of the state for severe wind/ storms/tornado/ or severe microbursts?
I have marked that line in black
looks chronic..
Although Thursday dawn ,4 am, is not prime time . So l reckon the timing as this goes through could be the difference between a strong change at night versus a severe weather event in the afternoon l would have thought
That convergence line looks wicked..
