Ahead of the cold front in southeast Kansas, temperatures were in the mid-80s with dewpoints in the mid-70s. Surface winds were from the south in the warm sector.

Chase Log: Not much to say about this day...we drove up I-335 towards Emporia, thinking we could play either along the warm front a bit further north and east, or along the cold front to the south. Some grunge storms stayed around northeast Kansas for much of the day, and we wound up waiting around for a while for clouds to start bubbling in our area.

By early evening, storms had started to form along the cold front, with the biggest cluster up in northeast Kansas. The storms quickly lined out though, so we didn't have much to play with aside from a semi-isolated storm in front of the line for a bit.
