7AM EST
thumbnail of 24-hr precip ending 12z 24-hr Accumulated Precipitation During Previous Hydrologic Day
(This image can be seen in more detail by clicking on the image or its label.)  It shows the 24-hr precipitation accumulation for the previous hydrologic day (ending at 7AM EST) as computed from precipitation processing software.  This product is updated usually by 8AM EST each day.

thumbnail of 24-hr HAS 12z QPF Previous 24-hr HAS QPF Image Ending 7AM EST
(This image can be seen in more detail by clicking on the image or its label.)  It shows the previous day's 24-hr total QPF generated by the HAS Unit at the RFC (which should be valid for the same period as the accumulated precipitation in the cell above [except for short delays when one image is updated before another]).  The QPF amounts shown here were used as input to NWS Hydrologic River Models. 

thumbnail of 24-hr absolute error of HAS 12z QPF Absolute Error of HAS Forecast
(This image can be seen in more detail by clicking on the image or its label.)  It shows the absolute error of the previous day's 24-hr total precipitation forecast generated by the OHRFC HAS Unit in comparison to actual precipitation estimates (see top row).

(This image can be seen in more detail by clicking on the image or its label.)  It shows the 24-hr precipitation accumulation for the previous hydrologic day (ending at 7AM EST) as computed from precipitation processing software.  This product is updated usually by 8AM EST each day.

thumbnail of 24-hr WPC 12z QPF Previous 24-hr WPC QPF Image Ending 7AM EST
(This image can be seen in more detail by clicking on the image or its label.)  It shows the previous day's 24-hr total QPF generated by the Hydrologic Prediction Center (which should be valid for the same period as the accumulated precipitation 2 cells above [except for short delays when one image is updated before another]).  This image is generated from national QPF guidance provided by the Hydrologic Prediction Center.
