Climatology for tornadoes in March is not promising:
Nebraska 1970-2003
Month: 03 Number of Tornado Days: 008 days Percent: 01.32 % Average
Tornado Days for Month: 0.24 days

South Dakota 1970-2003
Month: 03 Number of Tornado Days: 001 days Percent: 00.24 % Average
Tornado Days for Month: 0.03 days

Will climatology win out again?

I don't know, but it's too conditional and too far away for me to drive out there to find out. The GFS looks more believable to me in terms of surface features, showing the best theta-e air barely making its way into South Dakota by 21Z Friday to 0Z Saturday. Futher south, where the better instabilities wait, there's no support aloft.

That being said, if last night's ETA verifies in its entirety, storms along the warm front in South Dakota would definitely have the potential for tornadoes.

What I'm more interested in is Oklahoma on Saturday (I know it's a different thread so I'll be brief). Down there the moisture will have been in place for some time, and there's no question about wind profiles. I thought even last night's ETA showed strong potential, with the general co-location of moisture, shear, and lift. You can't try to pin ETA surface features down at 72 hours--just have to see if all the ingredients are in the same neighborhood.

That and March tornadoes in Oklahoma are not a once every quarter-century freakshow.

Back by popular demand, upper level support in West Texas just put Friday back on the map in the southern plains. No moisture questions here, just cap issues and winds aloft. The impulse swinging into the area Friday afternoon (see hot-off-the-press 12Z ETA) may address those issues. This s/w comes from the Mexican data void, so break out your channel imagery and profilers.

I see a caprock in my future. 8)

I live in Rapid City. Right now its partly cloudy and sunny out.
Towards the East you can see some thunderheads but no dark clouds. I can take pictures and post if anyone would like to see them since I am probably horrible at describing the weather. This is crazy to have T-storm warnings in March. Maybe we will have an active year this year?
