Storm Event Summary

February 8th-9th, 2011


An arctic air mass had already moved into place across the Missouri Ozarks and southeast Kansas with temperatures during the overnight hours on February 8th in the single digits to teens. Meanwhile, an inverted trough of low pressure and an associated upper level wave of energy pushed from the central and southern Plains into the lower Mississippi valley during the night of the 8th and during the day of the 9th.  Snowfall occurred from eastern Kansas into southwest Missouri and into much of Oklahoma and Arkansas with this event.  The highest snow totals were across Kansas and northern Oklahoma and into far northwestern Arkansas.  The southwest corner of Missouri did have up to a foot of snowfall with a sharp gradient heading to the northeast across the Missouri Ozarks. is the U.S. government's official web portal to all federal, state and local government web resources and services.
