More heavy rain in Eastern Montana possible! River stages.

A developing storm system has the potential for heavy rainfall in Eastern Montana and the Western Dakotas late this afternoon through Friday. Gusty winds for the plains as the result of this system on Friday and also a chance of showers and thunderstorms this weekend. Let’s hope we don’t see heavy rain anywhere in the state!

Here is the latest from the Glasgow weather service regarding the impact on the eastern part of the state:

“I know this is the last thing many of you want to hear, but we do have more rain in the forecast, with the heaviest amount still expected from midnight tonight through Saturday morning.

The precipitation totals from this morning through Friday morning:  http://www.hpc.ncep.noaa.gov/qpf/fill_94qwbg.gif

Friday morning through Saturday morning: http://www.hpc.ncep.noaa.gov/qpf/fill_98qwbg.gif
Concern here is with the rainfall in southern Canada coming into Montana’s streams.

This morning through Saturday morning (2 day total): http://www.hpc.ncep.noaa.gov/qpf/d12_fill.gif

So, at this point flash flooding could be a problem once again, and area creeks and streams are expected to rise once again.  The Yellowstone River is seeing rises from the mountain snowmelt, and an additional 1-1.5 inches across the basin will also lead to rises and increased flows.

The Milk River Basin is mainly impacted on the lower end of the basin from Hinsdale east.   Smaller creeks such as Antelope, Brazil and Cherry Creek could once again rise.

On the Missouri River basin below Fort Peck Dam, the small creeks and streams feeding it could also run very high.  Low water crossings could be impacted again, and areas that have had rapid rises in the past two weeks from rain, could see that again.” Tanya Fransen NWS Glasgow
