The NWS Storm Prediction Center has issued a

SUMMARY...Multiple corridors of severe thunderstorm development are

expected through late afternoon/early evening. Moderate to strong

the primary risks.

statute miles east and west of a line from 40 miles north of Garden

City KS to 15 miles southeast of Lubbock TX. For a complete

depiction of the watch see the associated watch outline update
