A cold-frontal passage and associated trough<\/span> entered the state from the northwest late Sunday evening, drastically changing the weather pattern for Colorado. Thunderstorms began to form in the Northwest Slope and Northern Mountains ahead of the front in the early evening, and included some high, gusty winds – a 46-mph gust was reported in Hayden. With the eastward progression of the front, showers became more widespread<\/span> over the Northern, Central, and Front Range Mountains but lacked the necessary instability for heavy rainfall due to the timing of the passage over the evening hours into the night. Temperatures were also lowered enough from the frontal passage for precipitation to fall as snow at high elevations, which limits runoff. <\/p>\n What's this? Can it be? Yes, the latest system brought a little bit of snow over the northern peaks overnight. This image is from Rabbit Ears Pass @ColoradoDOT<\/a>. It's not much but we will take it! Enjoy the cool, fall temperatures today! #COwx<\/a> #UTwx<\/a> pic.twitter.com\/HFrpCcVQhv<\/a><\/p>\n — NWS<\/span> Grand Junction (@NWSGJT) September 20, 2021<\/a><\/p><\/blockquote>\n \n
