Spot Forecast for Sand Lake Piles RX...UPDATED
National Weather Service Aberdeen SD
534 AM CST Tue Feb 11 2025

Forecast is based on ignition time of 0800 CST on February 11.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...Conditions at the burn site at 8 AM CST should
include temperatures at or below -20F degrees, and wind chill
values around -40F degrees. An Extreme Cold Warning is in effect.
Surface high pressure will be centered over the region, so winds
are expected to be rather light and variable or perhaps light out
of the west generally at or below 10 mph. These conditions should
persist during the day as the surface high gradually moves off to
the east and winds respond by becoming light out of the south by
the end of the day.
