It's been another exhausting day for firefighters in Colorado. The state is experiencing its worst wildfire season in a decade, with more than a half dozen fires currently burning.
The same pattern causing record heat in Colorado has developed over KELOLAND the past few days. Tuesday, drier air, gusting winds and much hotter temperatures will invade the Black Hills and western South Dakota. The increased threat of wildfires has already prompted a Red Flag Warning. It takes effect Tuesday morning at 10 a.m.
We should also be on the lookout for dry lightning. That's what sparked the Crow Peak Fire near Spearfish. And with a system tracking through Montana, high-based thunderstorms are possible in the Black Hills. This is key because lightning can strike even without rainfall.
