Thunderstorms today/tonight

Showers and thunderstorms are expected to develop across the Black Hills and western SD this afternoon and continue through the overnight hours. Thunderstorms imply lightning and that implies the potential for ignitions. The forecast radar reflectivity image for 1800 hrs tonight is shown below.



Although greenup has started, it has not progressed far enough to mitigate the fire risk presented by the dead grasses from last year's growing season. With the Lone Tree, High Plains, and Coyote Fires all occurring over the past week, we should be cognizant that a few lightning strikes may pose a threat for wildfire ignitions.

Luckily, these storms should come with showers but that in of itself does not preclude a fire threat. Lightning can strike outside the main core of the storm and holdover ignitions are possible. Total estimated precipitation through noon tomorrow is below.



Stay aware and don't be surprised if we see a few fires pop up tomorrow.
