by Rapid City, S.D. – A dynamic weather pattern is unfolding across Western South Dakota as a weak cool front passes through, bringing a mix of showers, smoke, and rising summerlike temperatures throughout the week.
Residents should prepare for light rainfall and increased smoke levels before temperatures climb into the 80s and 90s later this week.
Showers and Thunderstorms: A Brief Cool Front Passage
Clouds are rapidly building across the region as the weak cool front moves in, leading to an increase in shower activity, mainly concentrated in Northeast Wyoming. Although some thunder is possible, the most significant chance for storms is confined to areas outside Western South Dakota.
- Showers are expected to arrive after midnight in Western South Dakota.
- Rainfall activity is predicted to be light and taper off between 6 and 9 a.m. Monday.
- Any thunder and heavier showers will likely remain northeast of the state border.
Smoke Conditions: Extended Visibility Concerns and Health Advisories
Following the showers, smoke levels will increase due to ongoing wildfire activity, especially in Northeast Wyoming. This smoke is expected to spread into Western South Dakota during the early morning hours and persist through portions of Tuesday before gradually dissipating by evening.
“People with respiratory sensitivities need to be cautious about the amount of time they spend outdoors. Moving plans indoors as much as possible during smoke conditions is usually the best rule,” advised local meteorologists.
- Smoke will thicken in early morning hours, affecting air quality significantly.
- The smoke is projected to linger through Tuesday evening before tapering off.
- Health officials recommend limiting outdoor activities for vulnerable groups during smoke episodes.
Shifting to Summery Heat: A Warm Week Ahead
Once the smoke clears, summerlike temperatures will dominate the weather pattern moving into midweek. Daytime highs are expected to reach the lower 80s in the Hills, with mid-to-upper 80s across many areas. The warmest temperatures, approaching the lower 90s, are anticipated near Rapid City, Philip, and Kadoka.
- Temperatures will peak in the middle of the week with dry, summery conditions.
- Lower 80s expected in the Hills region.
- Mid-to-upper 80s and near 90 degrees forecast near Rapid City and surrounding areas.
This forecast underscores the variability typical of early September weather in the region, with a transition from cool, wet conditions to smoky skies and finally settling into warm, sunny days.
How to Stay Safe and Informed
- Keep abreast of updated weather alerts from local sources.
- Limit outdoor exposure during periods of thick smoke, especially if you have respiratory issues.
