Severethunderstorms will be possible from eastern Wyoming into adjacent portionsof South Dakota and western Nebraska on Monday as the cold front movesinto the Great Plains. The cold front will not make much southern progressacross the western U.S. however, and a shift toward zonal flow in themid-levels of the atmosphere will be accompanied by warming temperaturesthrough mid-week for the West.
