Bismarck (CSi) The National Weather Service on Friday May 27, 2016, issued the Flood and Water Resources Outlook…
This probabilistic Spring Flood and Water Resources outlook is for
the Missouri and James River basins of North Dakota and covers
the period of late May through late August.
The following message has four sections. The first provides some text
on the highlights of this outlook and conditions affecting the local
hydrology. The second section gives the current and normal/historical
risks of flooding as determined by the Ensemble Streamflow Forecast
model of the National Weather Service. The third section gives the
current probabilities for reaching flood stage at the listed forecast
locations. And finally, the fourth section covers the risk of the
river sites falling below the listed stages.
…Flood Outlook Highlights…
This outlook contains the probabilities for reaching flood stage
at the forecast points within the Missouri and James River basins
of North Dakota. Due to recent widespread and heavy rainfall, what
had been seasonally below normal probabilities for flooding are
now much closer to normal as recent rains now occupy a good
portion of the soil column’s capacity to hold water.
…Current Conditions…
Despite recent widespread and heavy rains, rivers tend to remain near
the low end of normal. Recent rains have brought soil moisture levels
into the normal, but not excessively wet range over the past couple of
weeks.
…Weather Outlook…
The month of May has generally seen scattered rainfall totals with no
really large areas being either exceptionally dry or excessively wet.
In the near term 6-10 and 8 – 14 day outlooks the expectation is for
above normal temperatures and below normal precipitation once the
current wet pattern subsides. This transitions into a generally equal
chance for above normal, near normal, or below normal precipitation and
temperature pattern for June with the three month outlook suggesting a
slightly enhanced chance for above normal temperatures while retaining
the equal chance for precipitation.
