Inundating Rainfall Expected Across the Region

From the NWS in North Platte

(via: http://www.crh.noaa.gov/lbf/?n=flashfloodconcerns):

On Tuesday upper level low pressure will move onto the Great Plains, as moisture gets pumped north ahead of this strong low pressure system. This upper low is expected to close off across northwestern Kansas by Tuesday afternoon. Of main concern is the North Platte River and areas of southwest into north central Nebraska for flooding, as the potential for heavy rainfall and possible flooding exists.

By Wednesday the storm system slides into north central Kansas and strengthens. This upper low will finally drift further east by Wednesday night into Thursday, as high pressure builds into the region behind the departing storm system.

Low level southeast winds will help develop some moderate to locally heavy rain across the high plains and into the Rockies, including the Black Hills. As recent heavy rains have saturated the ground in these areas, flooding and flash flooding concerns will increase with the impact of the incoming storm system.

Localized rainfall amounts of 2 to 4 inches will be possible across western and central Nebraska. Stay tuned to your local media or NOAA All Hazards Weather Radio for further information on the impacts of the approaching system.
