Big Severe Weather Event for Northern Plains Tuesday

A busy pattern continues Tuesday as showers move through the eastern Midwest and Tennessee Valley, which could result in some areas of heavy rain and flooding. Another system is moving through the northern Rockies and will move into the Northern Plains later Tuesday. Doing so should cause a significant severe weather event from the Dakotas down to Nebraska, with more isolated severe storms farther south to the Texas Panhandle. 

Highs: 50s/60s Pacific Northwest; 60s/80s Canadian Prairies, far northwestern Plains; 80s/90s elsewhere.
