Severe Thunderstorm Watch #0269

Locations Affected

Northwest Nebraska

Western and Central South Dakota

Eastern Wyoming

Severe Thunderstorm Watch Summary

Thunderstorm coverage is expected to increase over the next few hours from eastern Wyoming into northwest Nebraska and western/central South Dakota. Primary threat initially will be large hail, with the threat transitioning to strong to severe gusts as storms move from a more clustered cellular mode to a more linear, bowing segment mode. A few gusts over 70 mph are possible. There is also a low-probability tornado risk if a storm can mature while remaining discrete and cellular.

Severe Weather Threats

Scattered large hail and isolated very large hail events to 2 inches in diameter possible

Scattered damaging wind gusts to 70 mph possible

A tornado or two possible

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Northwest Nebraska
  Western and Central South Dakota
  Eastern Wyoming

* Effective this Tuesday afternoon and evening from 140 PM until
  900 PM MDT.

* Primary threats include...
  Scattered large hail and isolated very large hail events to 2
    inches in diameter possible
  Scattered damaging wind gusts to 70 mph possible
  A tornado or two possible

SUMMARY...Thunderstorm coverage is expected to increase over the
next few hours from eastern Wyoming into northwest Nebraska and
western/central South Dakota. Primary threat initially will be large
hail, with the threat transitioning to strong to severe gusts as
storms move from a more clustered cellular mode to a more linear,
bowing segment mode. A few gusts over 70 mph are possible. There is
also a low-probability tornado risk if a storm can mature while
remaining discrete and cellular.

The severe thunderstorm watch area is approximately along and 80
statute miles east and west of a line from 5 miles northeast of
Lemmon SD to 35 miles southeast of Scottsbluff NE. 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.

&&

AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 500. Mean storm motion vector
24025.

Severe Thunderstorm Watch #0270

Locations Affected

North Dakota

Severe Thunderstorm Watch Summary

Thunderstorms are expected to continue through this afternoon and evening along and ahead of a cold front moving into central North Dakota. Moderate to strong buoyancy and moderate vertical shear will support the potential for supercells, with large to isolated very large hail as the primary hazards. There is a low-probability tornado risk, mitigated by the expectation that cells will trend towards a more clustered mode rather quickly. Damaging gusts are also possible later in the convective cycle as bowing line segments become more common.
