Severe Thunderstorm Watch Number 444
NWS Storm Prediction Center Norman OK
1140 PM CDT Thu Jul 2 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Western Iowa
Northern Nebraska
Southeast South Dakota
* Effective this Thursday night and Friday morning from 1140 PM
until 600 AM CDT.
* Primary threats include...
Scattered damaging wind gusts to 70 mph possible
Isolated very large hail events to 2 inches in diameter possible
A tornado or two possible
SUMMARY...Occasionally strong to severe thunderstorms are expected
to continue early in the overnight mainly across northern
Nebraska/far southeast South Dakota, but may further increase and
gradually organize as they progress east-southeastward into western
Iowa. Bouts of large hail and damaging winds will be possible, and
damaging winds could become a bit more prominent should a
well-organized cluster/linear MCS develop overnight.
The severe thunderstorm watch area is approximately along and 45
statute miles north and south of a line from 10 miles south
southwest of Ainsworth NE to 50 miles east southeast of Storm Lake
IA. For a complete depiction of the watch see the associated watch
outline update (WOUS64 KWNS WOU4).
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 441...WW 442...WW 443...
AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 60 knots. A

MD 1461 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR NORTHERN ILLINOIS...FAR NORTHWEST INDIANA...FAR SOUTHWEST MICHIGAN

Mesoscale Discussion 1461
NWS Storm Prediction Center Norman OK
1143 PM CDT Thu Jul 02 2026
Areas affected...Northern Illinois...Far Northwest Indiana...Far
Southwest Michigan
Concerning...Severe potential...Watch possible
Valid 030443Z - 030645Z
Probability of Watch Issuance...40 percent
SUMMARY...The severe threat may continue for a few more hours across
parts of northern Illinois and far southwest Michigan. Isolated
severe gusts and hail will be the primary threats. The threat may be
enough to consider watch issuance.
DISCUSSION...Latest surface analysis shows an outflow boundary
extending from eastern Iowa east-northeastward into northern
Illinois, along which an east-to-west corridor of strong to severe
storms is ongoing. The storms are located along a relatively tight
gradient of moderate instability, where MLCAPE is estimated by the
RAP in the 2000 to 3000 J/kg range. In addition, the storms are
located along the southern edge of a 40 to 50 knot mid-level jet,
which is providing enough deep-layer shear for organized storms.
Low-level lapse rates are still steep along this instability
gradient, suggesting that a wind-damage threat will continue to be
possible with the stronger storms. Hail could also occur. As
instability decreases in the early overnight period, the severe
threat should eventually decrease.

Mesoscale Discussion 1460
NWS Storm Prediction Center Norman OK
1040 PM CDT Thu Jul 02 2026
Areas affected...Eastern Montana
Concerning...Severe potential...Watch unlikely
Valid 030340Z - 030545Z
Probability of Watch Issuance...20 percent
SUMMARY...A wind-damage and hail threat will likely continue across
part of eastern Montana late this evening. The threat is expected to
become more isolated with time, and additional watch issuance
appears unlikely.
DISCUSSION...The latest radar imagery over eastern Montana shows a
line of strong to severe thunderstorms ongoing about 70 statute
miles to the south of Glasgow. The storms are located just to the
northwest of a surface low in an area where surface dewpoints are in
the mid to upper 50s F, and MLCAPE is estimated by the RAP around
1000 J/kg. The line currently has a wind-damage threat, which is
being supported by very steep lapse rates in the low-levels. This
line may continue to remain intact as it moves toward the
Montana-North Dakota state line late this evening. Hail could also
occur within the strongest of cores. However, as instability weakens
across the region, the line of storms is expected to become more
disorganized with any severe threat becoming marginal and isolated.

Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0745 PM CDT Thu Jul 02 2026
Valid 030100Z - 031200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS FAR
EASTERN SOUTH DAKOTA INTO FAR SOUTHWEST MINNESOTA AND EXTREME
NORTHWEST IOWA...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
THE NORTHERN HIGH PLAINS TO THE GREAT LAKES AND WESTERN KANSAS...
...SUMMARY...
Scattered severe storms are still possible from the northern Plains
into the Midwest and Great Lakes regions this evening. More isolated
severe storms will be possible across the Central High Plains.
...High Plains into the Midwest...
Several clusters of thunderstorms are ongoing across portions of the
Dakotas into northern Iowa and southern Wisconsin/northern Illinois.
Across the western Dakotas, clusters of multi-cell and supercells
are ongoing. Given moderate instability and some supercellular
modes, large hail to very large hail and damaging wind will continue
to be a threat through the evening. Additional thunderstorms may
move out of Montana and or southern Canada through the evening with
additional chances for large hail and damaging wind.
A cluster across southeastern South Dakota moving into
Minnesota/Iowa has a history of producing significant gusts 90-100
mph. More recent observations have been around 60-70 mph. It is
likely that the damaging wind potential will continue downstream for
the next couple of hours, with potential for additional development
along the trailing outflow into northern Nebraska later this
evening. The 00z sounding from OAX sampled a large cape profile with
steep low to mid-level lapse rates.Confidence in exact evolution
remains low but some CAM guidance does suggest a secondary MCS
structure may move eastward later this evening across northern Iowa.
Given the large MLCAPE gradient extending across southern South
Dakota into northern Iowa and a continued reservoir of steep low to
mid-level lapse rates, this may pose additional potential for
damaging wind through the evening.
...Central High Plains...
A few isolated supercells are ongoing across portions of eastern
Colorado, southern Nebraska, and western Kansas. These have had
occasional stronger MESH cores around 2 inches. The 00z sounding
from DDC sampled strong instability and steep low to mid-level lapse
rates amid large dew point depressions within the near surface
profile. Given strong deep layer shear, inverted v soundings, and
moderate to strong instability, these supercells will continue to
pose a risk for large to very large hail and severe wind.
...Northeast...
A line of thunderstorms is sagging southward out of Quebec. These
may pose some potential for a few instances of strong to severe wind
through the evening. See MCD#1455 for more information.
