Spot Forecast for Old Oak...Vermillion Fire
National Weather Service Sioux Falls SD
1130 PM CDT Sat Oct 19 2024

If conditions become unrepresentative, contact the National Weather
Service.

.DISCUSSION...
Winds will remain light through the overnight/early morning hours,
which will lead to variable wind directions which may favor local
terrain and thus differ from the direction specified in the hourly
forecast below. The light winds and decoupled boundary layer will
also lead to poor smoke dispersal overnight through mid-morning.

Southwest winds will quickly increase after daybreak, leading to
elevated fire danger and potential for rapid fire spread by midday
as wind gusts of 25 to 30 mph become more prevalent.
