Moisture/humidity from the Gulf and mid and upper level subtropical moisture will combine to bring periods of rainfall (locally heavy) Tuesday. On Wednesday the remnants of Hurricane Polo will likely bring additional potential heavy rain. The areas shaded in yellow stand at least a 15% chance (slight risk) of flash flooding within 25 miles of a point.
Rain chances return today through Wednesday night across all of western and north central Nebraska. On Wednesday, an upper low pressure system (containing the remnants of Hurricane Polo) could bring a slight risk for flash flooding to parts of the area.
