National Weather Summary for Monday, March 6, 2017

by David Moran, on Mar 6, 2017 11:29:46 AM

Thunderstorms are expected to develop on Monday across portions of the Plains and mid-Mississippi Valley along a cold front. Snow will continue for portions of the Pacific Northwest through noon Monday as cold air filters into the region. As an area of low pressure continues to track eastward across the Plains, snow is likely across portions of the northern Plains. Elevated winds and seas will continue for portions of the Gulf of Mexico as a ridge of high pressure persists over the eastern US.

Region 1
An intensifying area of low pressure in the Dakotas will push northeastward into southern Manitoba and Ontario over the next day. A trailing cold front will extend southwestward from the low into Missouri, Kansas, and Oklahoma. Daytime heating will allow for enough destabilization for the development of severe thunderstorms ahead of the cold front during the afternoon. Isolated severe thunderstorms will be most likely from central Minnesota southwestward into eastern Kansas from the mid afternoon through the early evening. Large hail and damaging winds will be the primary hazards, but a few tornadoes will be possible if any isolated storms form ahead of the front. High resolution models are indicating the potential for strong supercells across southeastern Kansas this evening between 6pm and 10pm. Late this evening through early tomorrow morning, a squall line with damaging winds and perhaps an isolated tornado is forecast to progress southeastward from southern Minnesota into eastern Oklahoma. The line will more than likely weaken with a few instances of damaging wind before it moves into the mid-Mississippi and Ohio Valleys near daybreak tomorrow.
