— NO Flood Threat Today<\/em><\/p>\n

Though it certainly may not feel like it outside, today’s weather map has “Fall Is Here” written all over it (see water vapor image below). A potent large-scale trough<\/span> is entering the west coast of North America. The resulting dynamics will help develop a low-pressure circulation over the northern U.S. Rockies by later this afternoon. Meanwhile, a push of subtropical moisture is also noted over southern California. In fact, the eastern fringes of this have already made it into Colorado: the precipitable water<\/span> has jumped from 0.4 inches yesterday to 0.8 inches this morning. Note that this moisture transport is from the west (as opposed to south or southwest), potentially signalling that the Southwest monsoon<\/span> may be waning. Collectively, these factors will support a continuous, widespread<\/span> light to moderate rainfall across the Continental Divide<\/span>, and locations to the west. However, the fast steering winds (increasing to 35mph and higher) and unfavorable moisture profile (low-levels remain dry) will preclude the threat of heavy rainfall. Thus, we get an optimal result: beneficial widespread<\/span> rainfall, but no flood threat.<\/p>\n
