After a day of funnel clouds teasing us in southeast Colorado, we found ourselves crossing the border back into Kansas just before sunset, as the storm we had been lurking around all day weakened in intensity overall and began to join a developing line of storms in the area.

Chances of a tornado were now assumed to be over for this storm.  There was a much more prominent storm moving towards the northeast slowly, well ahead of the developing line which we were just in front of at the time.

As darkness ascended upon us and the day came to a close, something ominous was brewing.  A deep, violent rumbling could be heard in the open skies…coming from the car.
