Valid 140048Z - 140215Z The severe weather threat for Severe Thunderstorm Watch 408, 409 continues. SUMMARY...Severe thunderstorm complex will propagate southeast this evening. New Severe Thunderstorm Watch may be warranted downstream. DISCUSSION...Numerous robust thunderstorm clusters are gradually merging into a larger complex early this evening. Over the last hour or so, an expanding precip shield is beginning to evolve and an MCS now appears imminent as the convection propagates southeast. Sustained southwesterly 1km inflow appears to be aiding new updrafts along the western flank of the MCS over northern MO. The majority of large hail reports have been noted across this region, and latest MESH data suggests this continues. Given the upscale growth and the available reservoir of instability immediately downstream over east-central MO into central IL, there is increasing confidence the leading edge of this activity will spread beyond ww0409 shortly. New ww may be warranted soon. ...Darrow.. 06/14/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!668KJYZLvoXyENXDxwFSoFGuSkfWQMHjCRxKGMOOjL-1S-uSsH4ZA6061F9Ebr4UBcAQIugUO= aRzkxSbEUCGHNV5Bq4$ for graphic product...
