Nearly the entire northeast quadrant of the state is no longer experiencing any drought conditions, along with a pocket of Huerfano and Pueblo counties. Overall, the percent area of the state experiencing no drought conditions increased to over 23%, compared to 13% last week, and 0% of the state just three months ago. On the western half of the state, extreme to exceptional drought conditions are still present, with really no change in the percent area from last week. <\/p>\n<p><a href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd.png\"><img loading=\"lazy\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd-1024x791.png\" alt=\"\" width=\"910\" height=\"703\" class=\"aligncenter size-large wp-image-13926\" srcset=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd-1024x791.png 1024w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd-300x232.png 300w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd-768x593.png 768w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd.png 1056w\" sizes=\"(max-width: 910px) 100vw, 910px\"\/><\/a><\/p>\n<h4 class=\"collapseomatic \" id=\"id6a1c7aa3443f4\" tabindex=\"0\" title=\"Click Here For Map Overview\">Click Here For Map Overview<\/h4><div id=\"target-id6a1c7aa3443f4\" class=\"collapseomatic_content \">\n<p>The 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.
