— Flooding is NOT expected today<\/p>\n

The impressive large-scale trough<\/span>, centered over southwest Ontario this morning continues to rule the weather pattern in the Central Plains and Rocky Mountain states. The water vapor image, below, shows several disturbances (indicated by tan lines) rotating around the main low-pressure like spokes on a bicycle wheel. The southern disturbance is currently causing light to moderate rainfall in the Southeast Plains. In its wake, sunshine rules the land across central and northern Colorado.<\/p>\n

The sunshine will be limited as clouds are streaming in from Wyoming. Looking ahead, it is this northern disturbance that will affect our weather this afternoon, evening and into the overnight hours. As it quickly moves south, it will cause mid-level lift, and scattered<\/span> to numerous<\/span> showers this afternoon and evening basically across the entire state (with perhaps slightly more coverage east of the Continental Divide<\/span>). If this setup occurred later in the summertime, it could be conducive for a flood threat. However, today, moisture values are rather low with precipitable water<\/span> values only in the 0.4-0.6 inch range. Thus, instability will be suppressed. Furthermore, storm motions will be swift, 35mph+, limiting rainfall in any given locale. Collectively, the best chances of a weak thunderstorm, and associated higher rainfall rates, will be in the Palmer Ridge and Southeast Plains. Even there, though, rainfall intensity will be light to moderate and a flood threat is not warranted.<\/p>\n

A second impact of the large-scale trough<\/span> is a cooler than normal atmosphere. This will promote more high-elevation snowfall. Later this evening, expect snow levels to fall below 8,000 feet once again.<\/p>\n
