Scattered showers and thunderstorms will develop this afternoon and linger into the early evening hours. Rainfall amounts will range from one quarter inch to one half inch. However stronger thunderstorms could produce up to an inch or more of rain in less than 45 minutes in a few locations.
There will be a lull in activity this evening however rain and a few thunderstorms may increase in the northern foothills and mountain areas north of I-70 after midnight as upslope flow develops. Additional rainfall amounts of one half inch to one inch may occur between midnight and 6 am Sunday morning in some locations. For Sunday there will be periods of rain along with a few thunderstorms in the mountains and in and near the foothills. Additional rainfall amounts of 1 to 2 inches could occur in some locations by late Sunday afternoon.
Thus if this additional heavy rainfall occurs then there could be more flash flooding as the ground is extremely saturated.
