Hi Mike,
Yes have had issues for forecast soundings other areas too.
Ok, given it was 14th Feb, the radar echoes which track from the NW towards Cooindah are significant given the distance from the radar, but can't tell if it's a supercell.
Darwin morning sounding. The evening sounding stopped at the 750hpa level but does show 30-35 knots of WNW in the low levels: 950 to 800hpa which is quite strong.
