AREAS AFFECTED...SOUTHERN IOWA AND FAR NORTHERN MISSOURI
CONCERNING...SEVERE THUNDERSTORM WATCH 310...
VALID 111133Z - 111300Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 310
CONTINUES.
SUMMARY...THE THREAT FOR 60-80 MPH WINDS WILL CONTINUE IN SOUTHERN
IOWA. BRIEF TORNADOES ASSOCIATED WITH THE MCS WILL ALSO BE A
CONCERN. WITH DISCRETE DEVELOPMENT AHEAD OF THE MCS POSSIBLE, TRENDS
WILL NEED TO BE MONITORED FOR A POTENTIALLY GREATER TORNADO THREAT.
DISCUSSION...A COMPACT MCS WITH A HISTORY OF 60-80 MPH WINDS AND A
COUPLE OF BRIEF TORNADOES CONTINUES EAST WITHIN SOUTHERN IOWA. AHEAD
OF THIS MCS, WEAK THUNDERSTORM DEVELOPMENT HAS BEEN NOTED IN
SOUTH-CENTRAL IOWA. THE PRIMARY CONCERN THIS MORNING WILL CONTINUE
TO BE SEVERE/DAMAGING WINDS AS THE DOWNSTREAM ENVIRONMENT BEGINS TO
FURTHER DESTABILIZE. A SECONDARY CONCERN THAT NEEDS TO BE MONITORED
IS THE POTENTIAL FOR STRONGER DISCRETE DEVELOPMENT AHEAD OF THE MCS
NEAR THE SURFACE BOUNDARY. THE LOW-LEVEL JET CORE IS EXPECTED TO
MOVE INTO MORE OF CENTRAL/EASTERN IOWA THIS MORNING. THIS COULD LEAD
TO A GREATER TORNADO RISK IF DISCRETE STORMS CAN FORM/MATURE.
