Previous Day Next Day
After checking out the morning output from the RUC, it seemed fairly clear that W Central Iowa would be the place to be today, so we punched N from Council Bluffs, IA on the I29, stopping a couple of times to take readings, noting T/Td of as much as 91/66.  We eventually stopped at Sloan for a while not wanting to push too far N and watched the field of Cu fill in.  Several bases became darkened during this time and once it became clear the most impressive convections was firing just to our E we made a move, pushing E on the 141 to Denison, then the 30 to Carroll where we got the impressive pictures of convection (right).

As we arrived at Carroll we decided the cell seemed to be breaking down somewhat... how wrong could we be?... this cell became tornado warned after a sighting, but to get on terms we would have had to punch the core of the storm which was moving at 30mph... unlikely we would have managed it anyway.  We returned to Sioux City by the route given below being treated to a lovely display of mammatus by the setting sun (left). mammatus
Having settled in to a hotel in Sioux City we were treated to a number of cells surrounding us during the late evening from which I was able to make my first attempts at photographing lightning.  (I suspect grabs from the camcorder will be better than the following, but no time to process at the moment).  Notice that along the level of the trees in the centre of the cloud there appears to be a wall cloud back lit by the strobing lightning...

Finally grabbed the stills from the camcorder... nothing stunning but it gives a good feel for our evening.
