Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0752 PM CDT Wed May 11 2022

Valid 120100Z - 121200Z

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE UPPER MISSISSIPPI VALLEY...

...SUMMARY...
Severe thunderstorms will spread across the upper Mississippi Valley
this evening. Damaging winds, hail, and a few tornadoes remain
likely.

...Upper MS Valley...

Long-lived MCV that evolved over the northeast TX Panhandle Tuesday
night has tracked across eastern NE/southeast SD into southwest MN
early this evening. Considerable amount of convection has developed
ahead of this feature and a pronounced MCS has matured over
central/southern MN into extreme northern IA. Well-defined warm
front has advanced into southern WI, arcing across southern MN into
this MCS near MKT. Numerous discrete cells continue to form just
north of the warm front ahead of the leading squall line surge
associated with the MCS. Shear/buoyancy continue to favor the
potential for tornadoes, both with the discrete cells and embedded
QLCS tornadoes with the primary surge. Damaging winds appear likely
as this activity surges east/northeast along the warm front.

...Central/Southern High Plains...

Nocturnal cooling will prove detrimental to diurnally driven
convection that developed near the dryline this afternoon. Several
updrafts have begun to wane a bit early this evening though isolated
robust storms persist across western KS and far west TX. Overall,
this activity should gradually weaken after dark.
