MD 1067 CONCERNING SEVERE THUNDERSTORM WATCH 321... FOR PORTIONS OF FAR NORTHEASTERN KS AND NORTHWESTERN MO

Mesoscale Discussion 1067
NWS Storm Prediction Center Norman OK
0350 AM CDT Wed Jul 01 2020

Areas affected...Portions of far northeastern KS and northwestern MO

Concerning...Severe Thunderstorm Watch 321...

Valid 010850Z - 011015Z

The severe weather threat for Severe Thunderstorm Watch 321
continues.

SUMMARY...A strong to locally damaging wind threat continues with a
line of storms moving southeastward. Downstream watch issuance is
not expected at this time.

DISCUSSION...Recent observed wind gusts across southeastern NE from
a small, bowing line of storms have generally been in the 30-35 kt
range. There may still be potential for locally strong to perhaps
damaging winds in the short term along the apex of the line
currently along the KS/MO border, where inbound velocities from TMCI
show some enhancement to 45-55 kt around 1200 ft AGL. Regardless,
the modest, 25-35 kt southwesterly low-level jet being estimated by
recent VWPs from KTWX should continue to slowly weaken over the next
few hours. This should result in eventual weakening of the line as
it moves southeastward. Given this expectation, downstream watch
issuance to the southeast of ongoing Severe Thunderstorm Watch 321
is not expected at this time.
