Shallow Convection

A deep upper level trough worked through the midwest during the middle part of the week bringing much colder temperatures and overall unpleasant weather for this summer lovin' fella. However, during the day on Thursday, very cold upper level temperatures created lapse rates that were steep enough to kick off isolated areas of shallow convection across northern Illinois. Most of these little areas were having trouble getting their precipitation to make contact with the ground before evaporating due to the very dry lower levels. This in turn led to some photogenic 'virga'. I sat looking out my window for a while as I did some work on the computer thinking to myself that it might behoove me to grab the camera and go for a little drive. This ended up being a fairly decent idea on my part.

I immediately gave pursuit to one little cluster that had just moved through the DeKalb area that had a very photogenic precipitation shaft extending from its base, again, with much of it evaporating before reaching the surface. At one point, the slowly setting Sun cast a vibrant rainbow. I was unable to get to a worthy foreground however, before this disappeared.

I did still manage to have a little fun as daylight waned, and will slap a couple photos in the space below.

Attention is already beginning to turn to a potential major storm system at the end of the coming week. At the end of October, I'm always game to turn my attention to something well into the future to take my attention off of the gross weather currently in place. I'd like to get out and get back in the star trails game, but it seems we are back in that pattern of sunny days with a nice deck of upper level clouds moving in during the overnight that block out the stars. One can't complain after the northern lights display that I caught the back end of earlier in the week, I suppose.
