PUEBLO, Colo. — Southern Colorado is set for another unusually warm October day on Sunday, October 11, with temperatures climbing into the 80s and approaching 90 degrees across parts of the southeastern plains. At the same time, showers and thunderstorms could develop over portions of the mountains, creating a contrast between warm, dry conditions on the plains and unsettled weather at higher elevations.
According to the National Weather Service (NWS) office in Pueblo, above-normal temperatures are expected to continue Sunday, while the greatest potential for showers and thunderstorms remains concentrated over higher terrain, particularly near the Continental Divide.
The forecast could affect weekend plans for residents traveling across southern Colorado, including those heading outdoors, visiting mountain communities, or driving between the plains and higher elevations. Conditions will vary considerably by location, making it important to check local forecasts before heading out.
Southeastern Colorado Could See Temperatures Near 90 Degrees
The warmest conditions are expected across southeastern Colorado, where afternoon temperatures could reach the upper 80s and approach 90 degrees in some communities.
According to the forecast information provided by the National Weather Service, Lamar could reach a high near 90 degrees on Sunday. La Junta is forecast to approach 89 degrees, while temperatures around Eads could climb to approximately 86 degrees.
Pueblo is expected to reach the upper 70s, with Colorado Springs also forecast to see afternoon temperatures in the upper 70s. Farther south, Trinidad and Walsenburg are expected to experience highs in the 70s.
These temperatures would be notably warm for mid-October, extending a period of above-average warmth across parts of the region.
Residents planning outdoor activities may find the afternoon conditions comfortable, although temperatures approaching 90 degrees can still create a risk of heat-related discomfort, particularly during strenuous activity or prolonged exposure to the sun.
Anyone spending extended time outdoors should consider drinking water regularly, taking breaks in shaded areas, and adjusting activities to account for the warmer conditions.
Mountain Showers and Thunderstorms Could Develop
While the southeastern plains are expected to remain unusually warm, the weather could be less settled in Colorado’s mountain communities.
The National Weather Service expects additional showers and thunderstorms across portions of the higher terrain, with the greatest potential near the Continental Divide.
Areas around Buena Vista, Salida, Leadville, and nearby mountain communities could experience changing weather conditions throughout Sunday. The exact timing and location of any showers or thunderstorms may vary, so travelers should monitor updated forecasts before beginning mountain trips.
Temperatures at higher elevations will remain considerably cooler than those across the plains. Some mountain locations are forecast to remain in the 50s and 60s, creating a substantial temperature difference across relatively short distances.
Thunderstorms can bring lightning and brief periods of rainfall. Conditions may change quickly in mountainous areas, particularly for people hiking, camping, sightseeing, or participating in other outdoor activities.
Travelers should be prepared for cooler temperatures and possible rain, even when conditions appear warm and sunny at lower elevations. Checking the forecast for the specific destination is especially important because weather conditions in mountain communities can differ from those in Pueblo and southeastern Colorado.
What Southern Colorado Residents Should Expect Sunday
Sunday’s forecast highlights the different weather patterns affecting Colorado’s plains and mountains.
Across the eastern and southeastern plains, warmer-than-normal temperatures will be the main concern. Afternoon highs near 90 degrees in some locations could feel more like summer than fall, even as the calendar moves deeper into October.
In contrast, higher elevations could experience cooler conditions, scattered showers, and thunderstorms. This difference is particularly important for people planning to travel between the plains and the mountains, where temperatures and precipitation can change significantly along the route.
The forecast information provided does not indicate a widespread severe-weather outbreak. However, the possibility of thunderstorms means residents and visitors should continue checking official weather updates for changes in timing, location, or intensity.
People spending time outdoors in areas where thunderstorms develop should pay attention to changing skies and seek a substantial enclosed shelter if lightning approaches. A vehicle with a hard-topped roof can provide shelter when a suitable building is unavailable.
Drivers heading into the mountains should also allow extra flexibility in their plans in case rain or changing conditions affect visibility or travel comfort.
Where to Find the Latest Colorado Weather Updates
The National Weather Service remains the primary source for updated forecasts, weather alerts, and location-specific information across southern Colorado.
Residents can check the latest forecast from the NWS Pueblo office before leaving home, planning outdoor activities, or traveling into higher elevations. Forecasts may change as meteorologists receive new observations and refine expectations for showers and thunderstorms.
For Sunday, October 11, the main takeaway is a combination of unusually warm temperatures across the southeastern plains and the potential for afternoon showers and thunderstorms in portions of the mountains.
Lamar could approach 90 degrees, while Pueblo and Colorado Springs are expected to remain in the upper 70s. Mountain communities, meanwhile, should prepare for cooler temperatures and the possibility of changing weather throughout the day.
As conditions develop, checking the latest local forecast will help residents and visitors make informed decisions about their Sunday plans.
