Is the dust "wall" itself associated with any particular activity? It is a gust front? Is there any lifting going on? How high?
Actually, in this instance it may have been a gust front that raised the dust. There was a severe cold front and low pressure system producing the
wind, and there was large cumulus present with the dust storm, which is a good indication that it may have been the gust front causing it.
Another factor I ruled out was a dry microburst, but for that to occur there needed to be cumulonimbus present, and there wasnt any at that time.
There is lifting associated with both those, due to turbulent air mixing. Im not sure if you missed it at the start but we had gale force winds at the
time as well. We had sustained winds of around 40-43 knots and gusts over 50 knots, so yeah it was quite windy, lol
