KEY MESSAGES

- Showers and scattered thunderstorms are expected today. Lightning remains the primary hazard though gusty winds and some small hail may occur.

..Isolated Severe Thunderstorms Today

Instability across southeast North Dakota, the southern Red River Valley, and west central Minnesota will be supportive of a few strong to severe thunderstorms this afternoon and evening. Soundings confirm the presence of surface CAPE values generally just below 1000 J/Kg, but with very little shear. Dry air is in place at the surface, which supports a mention of wind gusts; however, with weak CAPE and shear, updrafts are expected to be somewhat short lived. With the taller storms, we could see just enough moisture loading to support 1 inch hail and wind gusts to 60 mph. Many storms, however, will struggle to reach severe strength.
