MD 2193 CONCERNING SEVERE THUNDERSTORM WATCH 640... FOR PORTIONS OF SOUTHERN MN INTO WESTERN WI

Mesoscale Discussion 2193

1156 PM CDT Tue Sep 01 2026

Areas affected...portions of southern MN into western WI

Concerning...Severe Thunderstorm Watch 640...

Valid 020456Z - 020700Z

The severe weather threat for Severe Thunderstorm Watch 640
continues.

SUMMARY...Thunderstorm clusters could continue to produce strong to
severe wind gusts and hail into the overnight hours. A downstream
watch into parts of southeast Minnesota and western Wisconsin is
uncertain, but a small downstream watch may be needed depending on
storm trends.

DISCUSSION...A cluster of storms over southern MN has weakened some
over the past 30-60 minutes as it has continued to lift northeast.
With this storm motion, convection has shifted further away from the
modest low-level jet oriented across IA, and northward into more
modest instability and midlevel lapse rates. Most recent observed
wind gusts have generally been in the 40-55 mph range, with 1.75
inch hail reported nearly an hour ago. Overall convective
organization has become more messy with time. Given overall
environment, sporadic severe wind gusts or hail could persist into
the overnight hours across southeast MN and perhaps west-central WI.
Damaging wind potential could increase if the cluster can track more
easterly near a surface boundary across southern MN. Depending on
short term trends, a small downstream watch could become necessary,
but remains uncertain.

WW 639 SEVERE TSTM IA MN NE SD 012050Z - 020400Z

URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 639
NWS Storm Prediction Center Norman OK
350 PM CDT Tue Sep 1 2026

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Far Northwest Iowa
  Far Southwest Minnesota
  North-Central and Northeast Nebraska
  Southeast South Dakota

* Effective this Tuesday afternoon and evening from 350 PM until
  1100 PM CDT.

* Primary threats include...
  Scattered damaging winds likely with isolated significant gusts
    to 80 mph possible
  Scattered large hail likely with isolated very large hail events
    to 2 inches in diameter possible
  A tornado or two possible

SUMMARY...Initial supercells will likely pose a threat for large
hail up to 2 inches in diameter. A tornado or two may also occur
with any sustained supercell, especially if thunderstorms can remain
at least semi-discrete through early evening as low-level shear
increases. Otherwise, a bowing cluster is expected to eventually
develop and pose a greater threat for severe/damaging winds up to
70-80 mph as it tracks generally eastward across southeast South
Dakota/northeast Nebraska and vicinity.

The severe thunderstorm watch area is approximately along and 60
statute miles north and south of a line from 60 miles northwest of
Burwell NE to 35 miles east southeast of Sioux Falls SD. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU9).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

&&

OTHER WATCH INFORMATION...CONTINUE...WW 638...

AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 70 knots. A
few cumulonimbi with maximum tops to 550. Mean storm motion vector
25030.

SPC Severe Thunderstorm Watch 639
WW 639 SEVERE TSTM IA MN NE SD 012050Z - 020400Z

URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 639
NWS Storm Prediction Center Norman OK
350 PM CDT Tue Sep 1 2026

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Far Northwest Iowa
  Far Southwest Minnesota
  North-Central and Northeast Nebraska
  Southeast South Dakota

* Effective this Tuesday afternoon and evening from 350 PM until
  1100 PM CDT.

* Primary threats include...
  Scattered damaging winds likely with isolated significant gusts
    to 80 mph possible
  Scattered large hail likely with isolated very large hail events
    to 2 inches in diameter possible
  A tornado or two possible

SUMMARY...Initial supercells will likely pose a threat for large
hail up to 2 inches in diameter. A tornado or two may also occur
with any sustained supercell, especially if thunderstorms can remain
at least semi-discrete through early evening as low-level shear
increases. Otherwise, a bowing cluster is expected to eventually
develop and pose a greater threat for severe/damaging winds up to
70-80 mph as it tracks generally eastward across southeast South
Dakota/northeast Nebraska and vicinity.

The severe thunderstorm watch area is approximately along and 60
statute miles north and south of a line from 60 miles northwest of
Burwell NE to 35 miles east southeast of Sioux Falls SD. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU9).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

&&

OTHER WATCH INFORMATION...CONTINUE...WW 638...

AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 70 knots. A
few cumulonimbi with maximum tops to 550. Mean storm motion vector
25030.
