Areas affected...Northeast Kansas...Missouri
Concerning...Tornado Watch 154...
Valid 090215Z - 090415Z
The severe weather threat for Tornado Watch 154 continues.
SUMMARY...A wind damage, large hail and tornado threat will continue
late this evening, affecting northeast Kansas and parts of Missouri.
The severe threat will likely persist into the early overnight
period necessitating a new watch further to the east.
DISCUSSION...The latest radar imagery shows a cluster of strong to
severe thunderstorms located from near Salina, Kansas northward into
far southeast Nebraska. These storms are located along the northern
edge of a moderately unstable airmass. The instability and moisture
gradient extends east-southeastward across eastern Kansas into
western and southern Missouri, along which a warm front is analyzed.
Storm coverage will continue to increase with a linear MCS
developing and moving southeastward along this gradient. As a cold
pool organizes, supercells that remain intact as the line forms,
will continue to have a threat for large hail and wind damage. The
WSR-88D VWP at Topeka, Kansas shows a looped hodograph with 0-3 km
storm relative helicity near 450 m2/s2. This will continue the
tornado threat, especially with supercells. The wind-damage threat
is expected to increase as the linear MCS matures, continuing after
midnight as the line moves into western Missouri.
