Showers and thunderstorms moved through the Northern Rockies and Northern Plains on Tuesday. A low pressure system over western Canada pushed a trough of low pressure and associated cold front through the Northwestern corner of the nation. This system had obtained moisture from the Pacific Ocean, which allowed for showers and thunderstorms to spread from Idaho through the Dakotas. Some of these storms turned severe with strong winds and large hail. Heaviest rainfall was reported in Beach, North Dakota with a mid-day total of 1.47 inches of rain. Strong winds with gusts over 60 mph blew down trees and power lines across Idaho and western Montana. The strongest wind gust was 72 mph reported at Craters of Moon, Idaho. High wind advisories remained in effect for most of the North-Central U.S.

Ahead of this system in the Plains, a trough of low pressure pushed warm air into the Upper Midwest and Great Lakes, which produced a warm front that kicked up scattered showers and thunderstorms. These storms have not yet turned severe. This warm air from the south allowed for high temperatures to range from 10 to 15 degrees above seasonable from the Southern Plains through parts of the Upper and Mid-Mississippi River Valley.

In Texas, a strong but small trough of low pressure over eastern Texas pulled abundant moisture in from the Gulf of Mexico. This triggered widespread showers and thunderstorms, some areas saw periods of heavy rainfall and strong winds, but severe storms have not been reported.
