MD 0200 CONCERNING TORNADO WATCH 29… FOR SOUTHEASTERN IOWA AND FAR NORTHEASTERN MISSOURI
Mesoscale Discussion 0200
NWS Storm Prediction Center Norman OK
0751 PM CST Sat Mar 05 2022
Areas affected...Southeastern Iowa and far northeastern Missouri
Concerning...Tornado Watch 29...
Valid 060151Z - 060345Z
The severe weather threat for Tornado Watch 29 continues.
SUMMARY...Storm mode has trended more linear in WW 29. Low-level
wind fields will still support damaging wind gusts and brief
tornadoes.
DISCUSSION...Modest destabilization continues ahead of a broken line
of quasi-linear storms in eastern Iowa and far northeastern
Missouri. Though storm mode has trended less discrete, regional
radar velocity data has shown periodic embedded circulations
developing within the line segments. A couple of measured severe
gusts were reported within the last hour in eastern Iowa. Given the
strong low-level shear and veering seen on the KDVN VWP, there will
be continued potential for this sort of activity. Damaging winds and
brief tornadoes will be the primary threats. The observed DVN 00Z
sounding showed an 8 C/km mid-level lapse rate which would also
support marginally severe hail, despite the less favorable storm
mode.
