Moisture also continues to increase, albeit slowly, as weak southeasterly flow brings in moist air from the Southern Plains. Added to the mix is an approaching disturbance from the southwest (see water vapor image below) that will cause upward motion downstream of its vorticity axis. Collectively, expect shower and storm coverage to increase today across southwest and eastern Colorado. Most rainfall will be of the light to moderate variety, and not pose a flood threat. However, two areas are exceptions to this rule. First, along the Raton Ridge, early instability will provide <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;scattered&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;25-40% areal coverage&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>scattered<\/span> storms that will be capable of heavy rainfall due to slow storm motion (much like Monday).
