We are seeing cool and comfortable temperatures to start our day on the Western Slope, but it’ll be a different story this afternoon. High temperatures look to reach the 90s and triple digits for most of the region today, and heat advisories will be in effect for the Grand Valley from noon to 8pm today. Skies will stay clear and sunny all day. Hot highs will carry into tomorrow, but we will start to see some changes in our weather pattern. High pressure will drift to the south tomorrow afternoon opening up moist southwesterly flow. This will push in some cloudier skies for the afternoon hours, and refuel chances for some mountain showers. At the upper levels of the atmosphere a trough will move in from our west at the end of the weekend. This will knock our highs back to our summer time normals in the mid 90s, and increase chances for scattered afternoon thunderstorms for Sunday, and early next week. Relief from the heat is on the way, but it is still a few days out.
