Denver began Tuesday with muggy conditions, tying its highest dewpoint in 17 years. 💧 Denver's dewpoint (a measure of the amount of moisture in the atmosphere) of 66 degrees at 1 a.m. Tuesday tied the city's highest since 2008, almost equal to Dallas or Austin. The moisture in the air will fuel stronger showers and storms, leading to flash flooding concerns, in the days ahead. Details at the link in our bio. 💧 #cowx #9wx #dewpoint #9newsweather
