URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 535
NWS Storm Prediction Center Norman OK
635 PM CDT Thu Jul 30 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Central and Eastern Nebraska
* Effective this Thursday night and Friday morning from 635 PM
until 100 AM CDT.
* Primary threats include...
Scattered damaging winds and isolated significant gusts to 75
mph likely
Isolated large hail events to 1 inch in diameter possible
A tornado or two possible
SUMMARY...A linear cluster of severe thunderstorms will likely
progress into the northern portion of the Watch area through the
early evening and spread into eastern and southern parts of Nebraska
through the late evening. Scattered severe gusts 60 to 75 mph are
possible with the stronger thunderstorm cores and associated
outflow. A brief tornado is possible if a supercell can persist
south of the main east-southeastward surge with the convective line
over northern Nebraska through the early evening.
The severe thunderstorm watch area is approximately along and 80
statute miles east and west of a line from 50 miles south southwest
of Hastings NE to 40 miles west northwest of Sioux City IA. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU5).
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.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
SOUTH DAKOTA AND NEBRASKA...
...SUMMARY...
Thunderstorms with severe wind gusts and hail will be possible this
evening from parts of central South Dakota southward into
east-central Nebraska and northern Kansas. Isolated severe gusts may
also occur in parts of the central High Plains, northern Plains and
upper Mississippi Valley.
...Central and Northern Plains...
A mid-level shortwave trough is evident on water vapor imagery from
eastern South Dakota extending southwestward into Nebraska. Another
more subtle shortwave trough appears to be moving through the
northern High Plains. Strong to severe thunderstorms are ongoing
ahead of each of these features, along and near an instability axis
analyzed by the RAP from west-central South Dakota southeastward
into central Nebraska. The greatest potential for severe storms this
evening will be associated with a line segment that is located
across central and northeastern Nebraska, which is near and to the
northeast of the strongest instability.
Along the instability corridor, the RAP has MLCAPE in the 2000 to
4000 J/kg range. The North Platte 00Z sounding is just to the west
of the instability max and has 0-6 km shear around 30 knots, with
0-3 km lapse rates of 8 to 8.5 C/km. This environment will support a
threat for severe wind gusts as the line moves southward across the
remainder of central and eastern Nebraska over the next few hours.
The wind-damage threat could persist into the late evening and early
overnight, as the convective line moves from Nebraska into northern
Kansas.
Additional strong thunderstorms will be possible across parts of the
central High Plains and from the northern Plains into the upper
Mississippi Valley. However, instability is a bit weaker in these
two areas suggesting that any severe threat should be marginal.
