KUSA - After nine days of 90-degree temperatures, cooler air has arrived bringing a relief from the heat. The combination of this cool-down and monsoon moisture could cause flash flooding in some parts of Colorado Sunday.
Afternoon highs will be in the mid to upper 80s with storms developing first in the mountains. Scattered storms are possible along I-25 through late this afternoon and early evening. Brief heavy downpours are possible but rain amounts will be limited in the Denver metro area. Higher rain amounts will fall near the Foothills and the Palmer Divide. Expect gusty winds and a lot of lightning with the developing storms.
Burn scars like Waldo Canyon will be susceptible to flash flooding through tonight. A flash flood watch will be in effect through midnight for central southern Colorado.
Stronger thunderstorms are possible Monday afternoon, while locally heavy rain and flooding will cause some problems in Tuesday's and Wednesday's forecast. Below average temperatures are expected for the rest of the workweek.
