Spot Forecast for Antihorse RX Unit Quebec...USFS
National Weather Service Rapid City SD
846 AM MST Mon Nov 10 2025

Forecast is based on ignition time of 0900 MST on November 10.
If conditions become unrepresentative, contact the National Weather
Service.

.DISCUSSION...Dry conditions are expected this week with upper
level northwest flow. The upper ridge axis becomes centered over
the fire area by late Thursday, resulting in warm temperatures. As
the ridge axis shifts east Thursday night, the flow pattern will
become southwesterly, resulting in an increase in
moisture/humidity. A cold front moves through the fire Friday
afternoon, which will shift the winds from the south to the north.
There is a chance for precipitation Friday night, but at this time
a wetting rain (>0.1") looks unlikely.
