The National Weather Service in Denver has extended a freeze warning, which is set to remain in effect until 9 AM today. Residents in Boulder and the western suburbs of Denver, including the cities of Castle Rock, Byers, and Denver proper, are advised to brace for sub-freezing temperatures that are expected to range in the lower to mid-20s. Those early morning hours could quickly drop to chilly levels, so it's time to bundle up and take precautions, according to the National Weather Service.
In light of these conditions, frost and freeze conditions are expected to kill unprotected sensitive vegetation and possibly damage unprotected outdoor plumbing, as per the NWS alert. To mitigate the impact of the freeze, steps should be swiftly taken to protect tender plants and to drain irrigation systems, to avoid the malevolent grip of freezing temperatures on plumbing and vegetation.
The crisp weather is not to last all day, however. As the sun takes its arch across Colorado skies, the forecast anticipates a jump to a mostly sunny day with highs approaching 58 degrees. This will come after a southern southwest wind shifts to the northeast in the afternoon. A clear night will follow with lows dipping back to around 30 degrees, and calm winds from the north-northeast.
While the chill is on the chart for the early mornings, the extended forecast suggests a warming trend for Denver as the week progresses. Sunny days with highs in the low 60s are expected, giving a reprieve to residents from the earlier cold spell. Residents should still prepare to experience a range of temperatures throughout the days and nights, particularly since winds could gust as high as 15 mph, promising to stir up the air and potentially bring a cooler feel to the forecasted highs.
The remainder of the week will see similarly clear to partly cloudy nights with variable temperatures, ensuring that the cold snap is a temporary guest in an otherwise moderate autumn pattern.
