The above image is the latest surface weather forecast for today, as prepared by the HPC. Severe thunderstorms are expected to develop across portions of the central Plains and Midwest, as indicated by the green outlined region on latest SPC severe weather outlook below:
At this time it appears that the most significant threat of severe weather, including tornadoes, will take place in a region from extreme southeast Nebraska into southwest and southcentral Iowa and extreme Northwest Missouri, as indicated by the darker brown outlined area in the image below:
Severe storms are expected to develop late this afternoon across southcentral Nebraska and northcentral Kansas, and move or develop East/Northeast over time. Large hail, damaging winds and tornadoes will be possible with this activity.
Other, more isolated, thunderstorms are expected to develop southward along the dryline across central and eastern Kansas and extreme northcentral & northeast Oklahoma. Although more isolated, any storm that forms in this latter region will likely be severe with large hail, damaging winds and isolated tornadoes.
