Spot Forecast for Road 9 Fire...BIA
National Weather Service Rapid City SD
458 PM MDT Sun Jun 15 2025

Forecast is based on forecast start time of 1700 MDT on June 15.
If conditions become unrepresentative, contact the National Weather
Service.

DISCUSSION...Thunderstorms are expected to move toward the fire
area this evening. The best chance for storms over the spot
location will be after 1900 MDT. Some storms this evening may be
severe with strong winds and hail being the main threats, although
a tornado cannot be ruled out today. Given the nature of the
storms today, precipitation will be hit or miss. However, ample
moisture is available so that any stronger storms can be expected
to produce moderate to heavy rainfall. Winds will be generally out
of the southeast this evening, however gusty and erratic winds
near storms.

Excellent overnight RH recovery expected tonight (~85%) with mostly
cloudy skies; thunderstorm chances wane after 2200-2300 MDT.

Warm and humid again Monday with afternoon and evening thunderstorms
possible; strong winds, hail, lightning, and heavy rain are the main
hazards.

Near-daily chances of thunderstorms will persist into next week along
with a severe weather threat at times. Winds will shift from south-southeasterly
Monday morning, becoming north-northeasterly.
