Storm Potential Update

The 5% tornado risk was expanded this afternoon to include all of the eastern half of our viewing area.

Moisture is flowing northward which will aid in the instability but a lack of sunshine is inhibiting the potential somewhat. Individual cells will have to be watched in areas to the northwest of Springfield until the early evening hours for severe tendencies.

Otherwise, a squall line will eventually form and move southeast through our area the rest of the evening. Hail and bowing segments with damaging wind potential and a small risk for tornadoes are the threats.
