Tornado Watch #404

Tornado watch #404 has been issued for northeast South Dakota, southeast North Dakota, and western Minnesota.

The watch is valid until 10:00 PM CDT.

There is a high risk of tornadoes in this watch box, as high wind speeds in the atmosphere. Supercells are expected to form in due time, and they are expected to potentially become tornadic.

Moderate Risk for Northern Plains Today

The northern plains, including Minnesota, is under a moderate risk for today.

The jet stream is expected to increase deep shearing, and adding to high instability to create the scenario of potential tornadoes. The low itself will also be deepening, which in turn should tighten the surface wind field and increase surface conductivity for tornadic thunderstorms.

The images are the overall risk, hail risk, and tornado risk.
