Warmer temperatures and mostly sunny skies will start today. A weak disturbance will approach from the west this afternoon while a cold front moves south across the plains. The combination of features will spark off a few showers and thunderstorms mainly along and west of Interstate 25 late this afternoon. Any storm that does occur will be weak...with brief gusty winds and light rain. Conditions should remain dry across the plains of Wyoming and western Nebraska. Monday will see cooler and overall calm conditions. More active weather looks to return for Tuesday and Wednesday.
