The severe weather threat for Severe Thunderstorm Watch 200
SUMMARY...The potential for a tornado will continue from along the Sheridan/Decatur County line into the Norton/Graham County line.
Downstream backing winds and temperature/dewpoint increases are
DISCUSSION...A tornado has been confirmed near Selden, KS with a
supercell that has had relatively persistent 50-60 kt rotational
velocity on KGLD 0.5 degree velocity. The environment ahead of the
storm is expected to continue to support tornadic potential as winds
at Hill City and Norton have backed to east-southeast and
strengthened. Temperatures and dewpoints have also risen slightly. A complicating factor could be developing convection in the inflow
region of the storm, now evident in Graham County. This could
potentially reduce tornado potential quicker than expected.
