Cool overnight lows will make a return to Western Slope. Our morning lows will drop 5 – 10 degrees and fall to slightly below average temperatures thanks to a passing cold front. Unfortunately this cold front is not bringing any rain to the Western Slope. This cold front will have even more of an impact on our afternoon highs. Tomorrow afternoon expect high temperatures in the 60s for the valleys and 50s at the higher elevations. Cool northerly winds will continue to cool our morning lows for Friday. High pressure will begin to build back up again and we will return to the 70s for the valley just in time for the weekend. We will cool down once again at the start of next week.
