Possible Severe Weather for the High Plains Severe thunderstorms, due to a upper level low, will be possible for the high plains. A slight risk of severe weather exists for southern areas of South Dakota and northern areas of Nebraska. This means numerous severe thunderstorms could be seen today. A marginal risk of severe weather exists right outside of the slight area. Cities in this region could see isolated severe thunderstorms for today. The cities in the 15 percent risk might see winds around 60-70 mph. The cities in the 5 percent risk could see winds around 58 mph. The cities in the 15 percent risk might see hail from 1-2 inches in diameter. In the hatched area, cities could see hail above 2 inches in diameter. The cities in the 5 percent risk could see hail up to 1 inch in diameter. There is also a 2 percent tornado risk for today. Although the percentage is very low, it is still above zero percent. This means tornadoes are very possible today.
