A cold front advanced toward Iowa from the northwest during the evening hours of the 1st. The cold front by late evening extended from southern Nebraska, across far northwest Iowa, into northwest Wisconsin. Ahead of the front the airmass was quite unstable, albeit quite warm. Temperatures at the 700 mb level were around +12 C. with the freezing level approaching 16,000 feet. Lifted indices were around -6 C. The LCL was quite high, around 2000 meters, which limited the threat of tornadoes.
