But first, let&rsquo;s discuss Event #1. The aforementioned <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;trough&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;An elongated area of relatively low atmospheric pressure; the opposite of a ridge.&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>trough<\/span>, which has been anchored to the western US\/Canada for days now, will finally make its way to the east and weaken, bringing a slight uptick in moisture and broad-scale support for showers\/thunderstorms on Tuesday. A weak surface boundary will lay across eastern Colorado, providing a focus for a few thunderstorms over the plains. Only a couple weak showers\/storms are expected over the mountains, as moisture will be lacking compared to eastern regions. All in all, the storms are not expected to bring any flood threat, so Event #1 gets a &ldquo;No Apparent Threat&rdquo; designation. Stay tuned to tomorrow&rsquo;s FTB for the latest.<\/p>\n<p><a href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2016\/09\/WV_20160905.png\"><img loading=\"lazy\" class=\"  wp-image-3729 aligncenter\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2016\/09\/WV_20160905.png\" alt=\"WV_20160905\" width=\"548\" height=\"363\"\/><\/a><\/p>\n<p>In Thursday&rsquo;s FTO, our forecast mentioned the need to pay attention to a potential tropical cyclone off the coast of Mexico for our midweek storm chances, and one has indeed developed (red circle). &ldquo;Newton,&rdquo; as it is named, will recurve to the north\/northeast and push into the desert southwest over the next couple of days. The westerly flow aloft will keep much of the tropical moisture associated with Newton to the south and east of Colorado, so it does not appear to bring any flood threat to Colorado at this time. This will still need to be monitored closely by the FTB, as any shift northward in the track of the moisture will have profound effects on the forecast. Stay tuned for more on that in the coming days.<\/p>\n<p>Otherwise, the next chance at showers\/thunderstorms will appear early next week (Mon. 12th\/Tues. 13th) as an upper-level low\/<span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;trough&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;An elongated area of relatively low atmospheric pressure; the opposite of a ridge.&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>trough<\/span> tracks across the region. At this time, it appears to be a quick-hitting event, devoid of blocking flow on either side that would slow its progression.
