Strong northwesterly flow helped moved these storms to the SE throughout the morning, and they eventually exited the state by early afternoon. These storms stabilized the atmosphere over the San Juan Mountains, portions of the Front Range and far Southeast Plains. Thunderstorm from yesterday that moved into these regions quickly dissipated. Around 1PM diurnal heating created an upslope pattern and storms began to initiate over the high country starting in the north. The heavier rainfall and stronger thunderstorms formed over the Southeast Mountains, which had higher instability and more availability to moisture. As the storms moved to the SE off the higher terrain, they found themselves in a favorable environment over Elbert and Lincoln Counties. A cluster of strong storms formed that were able to produce heavy, local precipitation. Storms began to quiet down quickly after sunset, though some <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;isolated&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;less than 10% areal coverage&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>isolated<\/span> showers were able to lingering overnight in the mountains.<\/p>\n<p>Both the thunderstorms over Elbert County and the Southeast Mountains had areal flood advisories issued for heavy rainfall.
