Areas affected...west-central and central MO
Concerning...Tornado Watch 275...
Valid 272256Z - 280000Z
The severe weather threat for Tornado Watch 275 continues.
SUMMARY...Elevated thunderstorms potentially capable of a large hail
threat may prompt a new severe thunderstorm watch and replace
portions of Tornado Watch 275 which is set to expire at 7PM CDT.
The probability for a new severe thunderstorm watch is 50 percent.
DISCUSSION...Radar mosaic shows a cluster of thunderstorms across
central MO in wake of a bow echo located over far southeastern MO.
Surface conditions across central MO have cooled into the middle 60s
degrees F temperatures with lower 60s degrees F dewpoints. Yet,
steep lapse rates advecting eastward from the west will likely
maintain elevated instability and the risk for strong/severe storms
capable of mainly a large hail risk. Convective trends will be
monitored through 630PM CDT with a new severe thunderstorm watch
decision likely by 645PM CDT.
