A relatively warmer layer of air aloft held strong keeping any meaningful thunderstorm development at bay over NW portions of the District this evening. Now that temperatures are cooling off the threat for any thunderstorm activity has ended for the day. - Monsoon moisture will increase over the District on Friday and continue to impact NE Colorado Saturday and Sunday as a cold front moves through giving us all a nice reprieve from the heat. - Heavy rainfall chances increase significantly on Friday and are expected to peak Sat/Sun, likely lowering into early next week. With the way this monsoon season has been playing out the next few days will feature a high likelihood of flooding in or around the District. Be prepared! STORM RAINFALL POTENTIAL AND DURATION: No meaningful precipitation expected for the remainder of the overnight period.
