<\/a><\/p>\nJust when you thought the monsoon<\/span> season was over, mother nature decides to toss you another late season heavy rainfall event. But first, there’s going to be a quick 1-day event before a drying and warming trend begins for the weekend. For Event #1, a bit of mid-level lift is expected to track across the northern portion of the state, which should help produce some widely scattered<\/span> showers north of I-70 with residual moisture from this last system. Due to decreasing moisture and moderate to quick WSW storm motion, there is No Apparent threat issued. As we head into the weekend, High pressure is forecast to begin to rebuild over Texas\/Oklahoma. This should produce both drier and warmer conditions for most of the state, but weak, isolated<\/span> mountain showers may develop in the afternoons. By early next week, a few daily high temperature records may be broken over the far eastern plains as temperatures potentially reach into the mid to upper-90s °F for the area.<\/p>\n Event #2 will likely begin late on Monday into Tuesday after a cutoff Low<\/span> sets up off the west coast. It’s becoming more likely that the counterclockwise rotation from the Low paired with clockwise rotation around the High (over Texas\/Oklahoma) will produce strong southerly flow that will extended in to Colorado. If this occurs, as long-term guidance is suggesting, it will likely transport a late season subtropical moisture plume northwards and into the state.<\/p>\n The GEFS plumes below show the nice decrease in moisture that is forecast over the weekend, and paired with subsidence from the High, this should cause a downtick in the chance for precipitation. Looking ahead to Event #2, there is fairly good consensus between model members that PW<\/span> values will increase over the state by mid-week. With both east and west PW<\/span> values well above average during this period, an Elevated flood threat has been issued. There are still plenty of differences between model members regarding the magnitude of moisture, since this event is 5-7 days out, but there may need to be 1 to 2-day upgrade to a High threat in Monday’s FTO.<\/p>\n Scroll down to view more details about the two events outlined in today’s FTO.<\/p>\n Residual moisture and mid-level lift are likely to produce widely scattered<\/span> storms over northern Colorado, but there is No Apparent<\/span> flood threat issued.<\/strong><\/p>\n Widely scattered<\/span> showers are likely tomorrow over the northern tier of the state favoring the high terrain for coverage. Over the adjacent plains, rainfall is expected to be more isolated<\/span>. Max 30-minute rain rates up to 0.75 inches may be possible. With only isolated<\/span> brief and moderate rainfall rates anticipated, there is No Apparent flood threat at this time. In addition to rainfall, stronger storms that develop are likely to produce some brief windy conditions and lightning.<\/p>\n<\/a><\/p>\n<\/a><\/p>\nEvent #1:<\/strong> Friday (9\/<\/strong>16<\/strong>)<\/strong><\/h3>\n
