At the end of this set I'll get into some technical discussion about what made this storm special and why it did or did not do whatever it did.\n\nAnyway, the target was somewhere around Arthur and this storm fired up near Grand Bend along a surface trof riding under a mid level moisture plume. The storm quickly developed and tracked north but really looked like crap on radar, and I mean just CRAP!\n\nDave Patrick and I who met up just north of Aurther raced north on hwy 6 as the storm came into view and were greeted by this rapidly developing wall cloud.<\/div><\/div><\/div><div class='afg-row'><div class='afg-cell' style='width:100%;'><a class='afgcolorbox' rel='example419'  href='https:\/\/farm6.staticflickr.com\/5345\/8797171735_1f0bd4c7ef_b.jpg' title='Supercell & Wall Cloud 2'><img class='afg-img' title='Supercell & Wall Cloud 2' src='https:\/\/farm6.static.flickr.com\/5345\/8797171735_1f0bd4c7ef.jpg' alt='Supercell &amp; Wall Cloud 2 \u2022 &lt;a style=&quot;font-size:0.8em;&quot; href=&quot;http:\/\/www.flickr.com\/photos\/65051383@N05\/8797171735\/&quot; target=&quot;_blank&quot;&gt;View on Flickr&lt;\/a&gt;'\/><\/a><div class='afg-description'>This was really one of those &quot;wow, it going to probably drop a tornado soon, I feel like I'm in Oklahoma&quot; moments.

A couple neat things happened, a combination of tree scud and pooled moisture that was overrun by the warm boundary or forced up the escarpment allowing up slope cooling created dense pools of fog which get sucked into the storm making for some cool skies. (no pun intended)\n\nSecondly, while out in what was essentially the middle of nowhere Dave and I ran into Todd Rittinger, or well we were parked and he ran into us! This is the second time I've run into another storm chaser in the field in Southern Ontario this year.
