An update from the National Weather Service in Pleasant Hill says conditions appear to be coming together for a widespread damaging wind/derecho event impacting northern Missouri. The system is also impacting southern Nebraska and northern Kansas.
Storms have caused the issuance of several severe thunderstorm warnings and two flash flood warnings in parts of northwest Missouri. Trees have been reported down near Cainsville, Bethany and Trenton.
Thunderstorm activity is said to be rapidly growing ahead of an advancing cold front that will eventually interact with a low-level jet that continues to strengthen.
The Weather Service is concerned that instability near the I-70 corridor could lead to widespread and potentially significant wind damage, continuing as storms spread from northern Missouri into central and eastern Missouri overnight. Central Missouri could see “enhanced” wind damage and possible tornadoes.
There is also significant concern about heavy rain and flash flooding.
