A powerful storm system continues to move out of the Pacific Ocean towards the west coast of the United States. As this storm crashes on shore, it will spread into the central plains late in the weekend, and then take aim at the northern plains early next week. As is typical with late winter or early spring storms, this system will bring a variety of weather to the plains states severe weather is a possibility in the central plains Monday March 23rd through Wednesday the 25th. To the north of the low, widespread rain, possibly changing to snow will fall over the Upper Mississippi and Red River of the North Basins. Locally heavy rains, on the order of 1 to 2 inches are possible by the time the system moves east Wednesday. Isolated higher rain fall totals are quite possible.
This is a very dynamic system, and will have a significant impact to the weather across our region. The amount of rain, the intensity at which this rain falls, the areal coverage and how much of it turns to snow, will all impact the developing flood. Rain falling on the frozen, snow covered ground of the Sheyenne River Valley will run off very quickly; where the snow has melted but the ground, ditches and drainage systems are all still frozen, expect overland flooding to develop.
Below is the updated forecast of total rain for the Sunday March 22 through Wednesday March 25th. As the storm develops and moves into the plains over the weekend, the NWS will update these outlooks. Residents of the Red River Valley and Lakes Region need to pay close attention to this developing storm system.
