A borderline critical day

My two cents on today's wildfire potential:

The wildland fire danger across South Dakota is elevated today due to strong winds and RHs below 30% in many areas.


But conditions aren't nearly as critical as they could be because of the recent precipitation. Every reporting weather station (ASOS and RAWS) across the state has received a wetting rain within, at most, the last 10 days. If the exact same meteorological conditions as we are seeing today occurred after 20+ days since the last wetting rain, I'd be far more concerned about the potential for large fire growth.

It's definitely windy out there (and a bit dry) but historically we just don't see big fires this soon after widespread precipitation events.
