There has been a downtick in the available moisture due to the location of the High, which is helping to produce the clear skies seen in the visible satellite imagery below. There is some mid-level energy that&rsquo;s combining with the residual moisture to produce some cloud cover and light rainfall over northwestern Colorado. However, the main moisture axis is marked by a green dashed line below, which is both south and east of the state.<\/p>\n<p><a class=\"keychainify-checked\" href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2022\/07\/vis_20220707.png\"><img loading=\"lazy\" class=\"aligncenter wp-image-18240\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2022\/07\/vis_20220707-300x192.png\" alt=\"\" width=\"700\" height=\"449\" srcset=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2022\/07\/vis_20220707-300x192.png 300w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2022\/07\/vis_20220707-1024x657.png 1024w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2022\/07\/vis_20220707-768x493.png 768w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2022\/07\/vis_20220707.png 1412w\" sizes=\"(max-width: 700px) 100vw, 700px\"\/><\/a><\/p>\n<p>Despite the overall decrease in moisture from yesterday, <span class=\"glossaryLink\"  aria-describedby=\"tt\"  data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;PW&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;(Stands for: Precipitable Water) The total atmospheric water vapor contained in a vertical column of the atmosphere.
