Areas affected...Central MO
Concerning...Tornado Watch 248...
Valid 192304Z - 200030Z
The severe weather threat for Tornado Watch 248 continues.
SUMMARY...Isolated damaging wind gusts and/or a brief tornado remain
possible for the next hour or so but a gradually diminishing severe
threat is anticipated.
DISCUSSION...Well-developed MCV and an associated line of storms
continues to move northeastward across central MO. Recent radar
imagery has shown decreasing storm intensity within the line but
more cellular activity has developed ahead of the line. Some brief
strengthening and/or forward propagation of the northern portion of
the line is possible as it interacts with this more cellular
activity and/or the warm front extending across the region. However,
after this brief intensification, the gradual diminishing trend
noted over the past hour or so is expected to continue as the line
continues into a less favorable thermodynamic environment
characterized by temperatures in 60s and MLCAPE less than 1000 J/kg.
Given the strength of the flow aloft and potential enhancement of
the low-level wind fields by the MCV, some isolated damaging wind
gusts and possibly a tornado are still possible but the overall
severe threat appears to be diminishing.
