It is interesting to watch weather systems move across the country by reading attackpoint logs. We had tornado warnings a couple of days ago. I guess it is the same mix of humidity and warm front that went through KC.
Yes, I've noticed some of the same with storms going up the east coast. Additionally, when I fly to places west of DC, it always seems to follow me back home whether I go to Minneapolis, Kansas City or San Antonio. In reality it probably is mixing. The forecasted tornado watch that kept me from going out probably was some of the same weather you got. As far as I know, no actual bad weather really ocurred. For me it just made me lazy.
Have fun at the Possum Trot! I'll be running in Wheaton Regional Park a few miles from home--not our prime terrain.
