Temperatures plummet as fall-like weather hits Colorado

In Colorado, the weather is experiencing a significant shift towards more fall-like conditions as of August 23, 2025. Temperatures have dropped approximately 10 degrees below average for this time of year in the Denver metro area. Expected afternoon highs will be in the upper 70s for the Front Range region, with southeastern Colorado seeing lows in the 80s and 90s on the western slope. This change in weather is due to the influx of monsoonal moisture that is returning to Colorado, which started on Saturday and is anticipated to increase over the following days. The forecast indicates a 30% chance of storms during the afternoons on Saturday and Sunday, with severe weather conditions potentially affecting the Front Range both days. The predicted severe weather primarily includes gusty winds and hail, both of which pose significant risks during this transition period. In addition, rain showers are likely to occur Sunday night into Monday, increasing the chances of flash flooding due to a combination of heavy rain and dry ground conditions. While this cool and wet weather might seem undesirable for some, it is welcomed news for many in the state facing drought conditions. The return of rain showers can significantly contribute to alleviating the effects of ongoing dry spells and promote healthier growing conditions in agricultural areas. In western Pennsylvania, which also faces shifting weather patterns, the approach of a cold front next week suggests a transition to cooler and more unstable weather. There, temperatures may drop significantly, leading to cool air also settling into the area. This upcoming week will see not only cooler temperatures but also the presence of several disturbances that's expected to deepen the cooling trend throughout the region. Some parts of the area may even experience isolated showers or thunderstorms associated with these disturbances as they make their way across the eastern and southeastern counties. As the weather patterns shift, the chances of precipitation are anticipated to decrease around sunrise on Monday before gradually intensifying again in the afternoon hours. This continual variation in weather will underscore the dynamic nature of late summer in both Colorado and surrounding regions.
