414... FOR PARTS OF NORTHEASTERN KANSAS....SOUTHEASTERN
NEBRASKA....SOUTHWESTERN IOWA...NORTHWEST MISSOURI
Mesoscale Discussion 1439 NWS Storm Prediction Center Norman OK 0935
PM CDT Sat Aug 07 2021
Areas affected...Parts of northeastern Kansas....southeastern
Nebraska....southwestern Iowa...northwest Missouri
Concerning...Severe Thunderstorm Watch 414...
Valid 080235Z - 080400Z
The severe weather threat for Severe Thunderstorm Watch 414 continues.
SUMMARY...An organized cluster of storms may continue to pose a risk
for severe wind gusts as it progresses eastward, mainly between the
Interstate 80 and 70 corridors of the lower Missouri Valley, through
11 PM-1 AM CDT. Trends are being monitored for an additional severe
weather watch east of WW 414.
DISCUSSION...An evolving cluster of storms continues to become better
organized with rear inflow intensifying in excess of 50 kt to the
south of a developing MCV now west of Concordia. Recent surface gusts
to 55+ kts have been observed at Concordia and Salina on the leading
edge of east-northeastward surging convective outflow, with forward
motion now in excess of 40 kt. New model output suggest that the MCV
will track into the Omaha area through 04-06Z, with the potential for
moist east/southeasterly inflow to maintain vigorous convective
development as far east as the Kansas City area. Activity may develop
as far northeast as Des Moines, if outflow associated with warm
advection driven storms near the Interstate 80 corridor, across
eastern Nebraska into western Iowa, does not interfere. South of the
Interstate 70 corridor, warmer elevated mixed-layer air may
increasingly tend to suppress thunderstorm development.

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM
CDT Sat Aug 07 2021
Valid 080100Z - 081200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE OKLAHOMA
PANHANDLE VICINITY NORTHEASTWARD TO SOUTHERN PARTS OF MINNESOTA AND
WISCONSIN...
...SUMMARY...
Scattered severe storms capable of producing damaging winds and hail,
will continue this evening and into the overnight period from the
central Plains to the upper Mississippi Valley.
...Discussion...
Several clusters of strong/locally severe storms are ongoing across
the outlook area at this time, particularly from the Texas Panhandle
northeastward into Nebraska, and then also over parts of central and
southern Wisconsin. The convection is ongoing ahead of an advancing
mid-level short-wave trough, within a moderately unstable environment.
Increasing low-level warm advection this evening -- tied to a
strengthening low-level jet -- will sustain vigorous storms across the
central Plains region this evening, along with likelihood for upscale
growth into one or more convective clusters. One of these clusters --
likely to be associated with a corridor of locally strong/damaging
winds -- is expected to evolve in the next couple of hours and move
across north central and northeastern Kansas/south-central and eastern
Nebraska, and possibly surviving into western Iowa later tonight.
Other strong/locally severe storms farther south, will likely spread
eastward into south-central Kansas/western Oklahoma, and also may
evolve overnight from the southern Minnesota vicinity eastward across
southern Wisconsin, where locally damaging wind gusts will be the
primary severe risk.
