Freeze Warnings were in effect for portions of the Northwest and Southwest Slopes as well as over the higher elevations in the Northern Mountains. With the jet over the state yesterday, it remained breezy during the afternoon. Thankfully, it doesn&rsquo;t look like there was much (if any) change in ongoing wildfire behavior. Generally, winds were in the 8 to 15 mph range (from the northwest) over the northern and central mountains. Slightly higher winds were recorded over the highest elevations. Gusts reached between 15 and 25 mph with a couple 30+ mph gusts recorded over the mountains. Near surface smoke was highest north, near the Cameron Peak\/Mullen fires, but most of this smoke was aloft along the Front Range and Urban Corridor. Much cooler temperatures were recorded yesterday behind the front, and the dry air mass\/subsidence kept rainfall out of the forecast. Light showers over the Southeast Mountains during the morning hours cleared out as dry air filled in from the north. Other than some cirrus over the Northwest Slope, it was a clear, fall day.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter wp-image-13355 size-full\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2020\/09\/24hr_min_temps.png\" alt=\"\" width=\"723\" height=\"498\" srcset=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2020\/09\/24hr_min_temps.png 723w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2020\/09\/24hr_min_temps-300x207.png 300w\" sizes=\"(max-width: 723px) 100vw, 723px\"\/><\/p>\n<p><span style=\"text-decoration: underline;\"><strong>Large ongoing Colorado wildfires update (as of 9:40AM from InciWeb):<\/strong><\/span><br>\nCameron Peak in the Medicine Bow Mountains: 124,026 acres; 21% contained<br>\nMiddle Fork Fire in Routt County: 7,897 acres; 0% containment<br>\nWilliams Fork in the Arapaho National Forest: 12,889 acres; 14% contained<\/p>\n<p>To see precipitation estimates over your neighborhood the last 24 to 48-hours, scroll down to the State Precipitation Map below.<\/p>\n<h4 class=\"collapseomatic \" id=\"id6a1cb73c71059\" tabindex=\"0\" title=\"Click Here For Map Overview\">Click Here For Map Overview<\/h4><div id=\"target-id6a1cb73c71059\" class=\"collapseomatic_content \">\nThe map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (<span class=\"glossaryLink\"  aria-describedby=\"tt\"  data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;QPE&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;&amp;lt;strong&amp;gt;Q&amp;lt;\/strong&amp;gt;uantitative &amp;lt;strong&amp;gt;P&amp;lt;\/strong&amp;gt;recipitation &amp;lt;strong&amp;gt;E&amp;lt;\/strong&amp;gt;stimate; an estimate of the amount of precipitation that has fallen at a particular location or across a region based on several different data sources, such as radar or satellite; QPE is often calculated using remotely-sensed data sources&lt;\/div&gt;\"  data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>QPE<\/span>) across Colorado.

The 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences.

Also shown optionally are vulnerable fire burn areas (post 2012), which are updated throughout the season to include new, vulnerable burn areas.
