These locations have already had heavy rain during the past few days and more is expected Saturday.
Highs will be in the low 80s on Saturday thanks to cloud cover. Storms will develop by early afternoon and scatter along the Front Range, especially during the afternoon and evening.
The storms will move slowly and bring a lot of rainfall. Flooding is possible because some locations have already received heavy downpours.
