...A long duration of moderate to heavy rainfall on saturated
soil will increase flood potential early next week...

The wet pattern continues as a strong low pressure system moves
into the northern plains early next week. Beginning Sunday night,
rain (with snow in the higher elevations) will overspread
northeastern Wyoming and western South Dakota. This slow-moving
system will bring a long duration of precipitation, which may be
heavy at times. By Wednesday evening, rain totals are expected to
range from 1.5 to 3 inches. Full ponds and creeks, as well as
saturated soil, will contribute to the potential for flooding.
