Tornadic storms that occurred over northeastern Kansas and northern Mi
ssouri on 4 July 1995 are examined by combining the latest in National
Weather Service technology with more routine datasets. The analysis p
rovides an insightful description of the meteorological setting and ev
olution that led to the severe weather on this day. Strong thunderstor
ms first formed where an outflow boundary intersected a cold front, th
en new activity was triggered along the outflow boundary itself. It wa
s found that small-scale outflow interactions may have played an impor
tant role in changing the nature of the convection already under way a
nd were associated with the two most damaging tornadoes of the day. Th
e case is also used to showcase how several new ''modernization'' data
sets can be used together in a quickly accessible manner to provide a
valuable and precise overview of a rapidly evolving meteorological eve
nt.
