We are seeing a clear start to the day on the Western Slope, but clear skies and dry conditions will not last. Once we get into the afternoon hours we will see several scattered rain showers and thunderstorms drift into the region. Storms will start to pick up around 4pm in the valleys, and the heaviest rain for today will be late this afternoon and evening. Highs for the day will be cooler than yesterday, but still in the 80s for most of the region. Chances for rain showers will continue through the overnight hours and all day Wednesday. Stronger thunderstorms will return to the region at 9am tomorrow. We will also see rain chances for most of the day on Thursday. Highs for the middle of the week will drop all the way down into the 60s and 70s. Due to heavy rain over the next three days flood watches have been issued for the Western Slope. Be careful driving in narrow canyons. The heaviest rain from this system will land on Wednesday afternoon. Once we get to Friday dry air will move in causing rain chances to clear up. With sunnier skies, and dry conditions expected for Friday and the weekend highs will return to the upper 70s in the Grand Valley by Saturday and Sunday.
