Right now we are seeing dry air and clear skies over the Western Slope. Thanks to these drier conditions morning lows are about 10 degrees below our summer time averages. The cooler temperatures will stick around for the start of the day, but afternoon highs will still be average for the day. As we move through the week moist air will begin to move into the Western Slope. Moist southwesterly flow will generate chances for scattered, afternoon mountain thunderstorms tomorrow, and this pattern will continue through the week. The best chance to see rain in the valley will be Thursday. Storms will mostly stay over the higher terrain, an form during the afternoon hours. With these much needed rain chances moving in, high temperatures will be rather stagnant in the 80s for most of the region this week.
