Look for a return of hot, dry, and breezy conditions tomorrow and Thursday which will likely lead to critical fire weather conditions over southwestern SD. Wednesday does look like the most critical of the two days.
Temperatures will be in the upper 80s to mid-90s across the area, minimum RHs will drop to below 20%, and south to southwest winds will be gusty from 15-30 mph.

Furthermore, these areas of southwestern SD have not seen much for rain over the past 2 weeks with some locales not seeing a wetting rain in over 3 weeks:
The VegDRI product shows much of this dryness across the region.
The primary threat will be over southwestern SD as this is where the hottest, driest, and breeziest conditions are forecast to be. The largest 5 fires since 2000 (table below) show similar conditions to what we have seen over the past 2+ weeks and to what we expect to see tomorrow. In short, pay attention and don't get complacent around new ignitions.
