Tonight is another mild spring night with the temperatures in the mid to high 30s for most of the region. Sunday looks to be another pleasant day with highs in the 60s to low 70s once again. Look for some isolated showers to develop over the mountains in the afternoon..with a HIGH FIRE DANGER through the San Luis Valley. The weather will become more active across Colorado early next week. A strong area of low pressure will move across the southern half of the state Monday and Tuesday. Heavy mountain snows and strong to severe thunderstorms across the eastern plains are possible Monday afternoon and evening. After a strong cold frontal passage on Tuesday, snow may be possible across the San Luis Valley, I-25 corridor, and the eastern plains. Some forecast uncertainty exists in the track of the low pressure center. Please continue to monitor for the latest.   (Please visit for more information.)
