The weekend storm is certainly still impacting the region, but the worst of the rain and/or snow is behind us. The radar from Mayville was recording rain across much of eastern North Dakota as of 12:30 PM CDT on May 11, 2015. That band should move east and slowly dissipate during the day, but still producing 0.25 inches to 0.50 inches of additional moisture potential.
The High Resolution Rapid Refresh Model (HRRR) projected radar movement for the rest of the day is presented below. There will likely be a bit more snow on the western edge of this band than what is shown.
Accumulated rain since Sunday is presented below for station in the North Dakota Agricultural Weather Network. Highest totals were near and south of Interstate 94. Linton (1.80″) and Wishek (1.86″) totals may be a bit low as that area recorded several inches of snow and some of that moisture may not have melted properly into the automatic rain gauge.
In addition to those totals the CoCoRaHS observers (Community Collaborative Rain, Hail and Snow Network) reports through mostly 7 or 8 AM are presented below for locations that reported 0.50 inches or higher.
Besides rain, there was also a significant snow in southern North Dakota. Besides the reports below there were others that reported 2 to 4 inches briefly that quickly melted. But the highest totals appeared to be in Sioux County in south central North Dakota.
Next threat of rain appears to be later Wednesday into Thursday, and then a more significant system on Sunday/Monday of next week.
