...Brief Landspout Tornadoes Possible...

At 225 PM CDT, conditions are becoming favorable for the development
of landspout tornadoes in and close to the Kansas and Nebraska
border. However, at this time it is unknown which if any storm would
produce a landspout. Any landspouts which develop are expected to
pose a limited threat.

Locations impacted include...
McCook, Norton, Oberlin, Indianola, Almena, Bartley and Norcatur.

To report severe weather, contact your nearest law enforcement
agency. They will send your report to the National Weather Service
office in Goodland.

Landspout tornadoes can form with a developing thunderstorm before
rain, hail, and even thunder is observed. Landspout tornadoes are not
usually associated with a wall cloud and are often difficult to
detect with weather radar.
