A cooler and more unsettled weather week lies ahead beginning this evening. At Noon a sharp cold front had blasted through Casper, WY (Casper at Noon was about 30 degrees cooler than Boulder and Denver). That front should move through Cheyenne this afternoon and then down the Colorado Front Range late this afternoon and into the evening. There will probably be some showers and thunderstorms around with the front (or just after the front) but some folks may miss out. Later tonight and Thursday morning will probably see the development of some areas of low clouds and drizzle.
A warmer air mass will try to make a comeback late Thursday or early Friday, but another cold front is likely from the north during the day Friday. After that it may be hard to squeeze in a truly warm day for a while, but I’ll update when we are closer to the weekend.
A large storm system will dominate the western United States this weekend and into early next week and is likely to bring mountain snow and valley rains, including parts of western Colorado. For the Front Range and eastern plains the chance for significant precipitation is not as certain, but not out of the question yet for the Saturday-Monday period.
