A Stormy Start for the Week

Monday and Tuesday will be busy weather days even though this depiction of the surface weather (the Sunday afternoon GFS) doesn't look impressive with a low near Omaha at noon Monday.

But there will be an outbreak of severe thunderstorms
across Louisiana, Mississippi and southern Alabama Monday afternoon and night with large hail, damaging wind and tornadoes. It looks like there will be short lines of severe thunderstorms. Heavy rain (2-3") will fall over eastern Arkansas, Mississippi and western Tennessee. The rain will be enough to cause flooding. The heavy rain will be over eastern Tennessee, eastern Kentucky, Alabama and northwest Georgia on Tuesday -- and there will be a lot of flooding there.

Meanwhile the Northern Plains will get some heavy snow Monday and the Upper Mississippi Valley will get blasted on Tuesday. Many areas will have 3-6" of snow and 35 mph wind. Western Minnesota and eastern South Dakota may pick up 10" of snow with the same for the Black Hills of South Dakota.

Washington State gets whacked Monday night and Tuesday with 2 to 4 inches of rain below 4500 feet and 2 to 3 feet of snow above 5000 feet.
