This has helped produce morning cloud cover over eastern Colorado and the Front Range. Moisture is limited to the bottom ~1km of the atmosphere, so expecting this to start burning off throughout the morning as dry air mixes it out. The clouds and the cold air behind the front will help keep afternoon temperatures down with highs slightly below normal. Subsidence over the state and a dry air mass will nix the chances for afternoon showers and thunderstorms. The clear skies will likely cause some low overnight temperatures, as the cloud cover last night helped act as a blanket for surface temperatures. Broken cloud cover is still forecast to increase over the northwest quadrant of the state and over the mountains this evening as the next system (orange &ldquo;X&rdquo;) starts to slip south into Wyoming.<\/p>\n<p>Cooler temperatures and an exiting <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;jet stream&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;Relatively strong winds concentrated within a narrow stream in the atmosphere.
