The last weekend of March will bring severe storm threats from the Midwest to the Gulf Coast in a pattern that has become familiar in recent weeks.

00:00The stormy theme is going to continue for some into the weekend here, with many areas facing scattered thunderstorms into a large area from Missouri, Arkansas, eastern parts of Oklahoma, and into other areas farther east.
00:12So this weekend, we've got severe storms moving through parts of the Midwest and South. Spring snow into parts of the upper Midwest and New England, and moisture will return as warmth eases in the east.
00:22This storm system is ultimately going to be coming from the Gulf of Alaska. It's still a long ways away here, so we have to, again, just kind of pace ourselves.
00:29And again, we'll get a better handle on the specifics on the exact timing of the severe weather and so forth as this gets closer to the lower 48 states.
00:38But we're going to have a huge contrast on the north side of this storm, separating the 30s and 40s from 70s.
00:44It might just be 110 miles, 120 miles between 40s and 70s at some points on Saturday afternoon.
00:51And on the north side of all this, we're going to be dealing with some sleet and freezing rain.
00:56We're most concerned about northeastern Wisconsin, northern parts of Michigan, and also parts of Ontario for some significant ice buildup that will bring trees down and power outages will be a result for some.
01:07But to the south of that snowy, icy zone, big storm system brings us that severe weather threat in many areas here.
01:13So we're going to be following this, and overall it comes in two phases. There are really two separate areas of low pressure, the first of which will be moving across the plains on Saturday evening.
01:23Here's our area of low pressure. We've got flow from the south driving moisture northward, and there will be some scattered strong thunderstorms with this one and maybe a few farther south as well.
01:31As that moves east and gets kind of gobbled up by a front, a new area of low pressure will be moving through a similar zone with strong and severe thunderstorms into the Ohio Valley, parts of the Mid-South, and the Ozarks there on Sunday evening and Sunday night.
01:45So Saturday, severe risk, Missouri, eastern Kansas, eastern Oklahoma, Arkansas, northeast Texas, Shreveport, Louisiana facing some of that.
01:53We've got a big zone here for Sunday, though, from Illinois, Indiana, and Ohio all the way down to east Texas, Mississippi, and Alabama.
02:00And that storm system with the front associated with it plows east here right into Monday, and that will be eastbound moving through the mid-Atlantic states and the southeast with severe thunderstorms, hail, flash flooding.
02:11And the risk is still possible for a tornado or two, but the greater threat there is going to be a little farther to the west and into Saturday and Sunday.
