Humid monsoon flow is moving into Colorado this week, delivering a break from recent heat and a multiday period of cooler, wetter conditions for much of the state. Forecasters say daytime temperatures along the Interstate 25 corridor will generally remain in the upper 70s to low 80s, and scattered storms are expected through the weekend.
"We are finally in for a nice break from the heat!"
What to expect this week
National and local meteorologists are projecting four days of below-normal highs after a stretch of 90-degree weather. The most widespread and intense showers are slated for Thursday and Friday, when models indicate higher moisture and instability could yield periods of heavy rain. That heavier rainfall raises the possibility of localized flash flooding in vulnerable areas, including burn scars, steep terrain and urban drainage corridors.
By Saturday and Sunday, forecasters still expect scattered afternoon and evening storms, keeping the pattern unsettled but likely less organized than midweek. Slightly warmer and drier conditions should return early next week, and another day reaching 90 degrees is not expected until Tuesday.
Where impacts are most likely
While much of the state will see some showers, the most noticeable cooling and rain are expected along and west of the Front Range, including the I-25 corridor. Local advisories will be issued if storm cells become slow-moving or extremely wet.
- Temperatures: Upper 70s to low 80s for daytime highs across the Front Range.
- Timing: Heaviest rain potential Thursday–Friday; scattered storms continue through the weekend.
- Hazards: Localized flash flooding, especially in burn areas and urban low spots.
Practical safety tips
Officials recommend residents keep an eye on local forecasts and be prepared for sudden downpours that can reduce visibility and produce rapid runoff. Key precautions include:
- Avoid driving through flooded roadways; turn around, don’t drown.
- Watch for rapidly rising water near creeks, drainage ditches and burned slopes.
- Secure outdoor belongings that could be swept away by storm runoff.
- Monitor local alerts and weather radars for warnings tied to heavy rainfall.
Short-term outlook and timing
Forecasts show the wetter, cooler weather holding through Sunday, with the greatest concentration of moisture arriving midweek and tapering only slightly over the weekend. Early next week looks comparatively warmer and drier, though forecasters caution that monsoon patterns can be variable and localized downpours remain possible until moisture diminishes.
Below is a compact view of the expected high temperatures and precipitation trend for the next several days across the Front Range corridor:
| Day | Forecast | Highs |
|---|---|---|
| Thursday | Scattered to numerous storms; heavier rain possible | Upper 70s–low 80s |
| Friday | Periods of heavy rain and storm chance; flash flooding risk | Upper 70s–low 80s |
| Saturday | Scattered afternoon/evening storms | Low 80s |
| Sunday | Scattered storms continue | Low 80s |
Residents should consult trusted local sources for hourly updates and the latest warnings. Many news outlets and agencies provide live radar and real-time alert services that can help people plan travel and outdoor activities during this unsettled stretch.
While the cooler temperatures will be welcome after several hot days, the increased moisture brings its own set of hazards. Awareness and simple preparedness measures can reduce the risk from flash flooding and other storm-related impacts as monsoon moisture moves through Colorado.
