— LOW<\/strong> flood threat for San Juans, Grand Valley, Central Mountains, Southwest Slope and Southeast Mountains<\/em><\/p>\n

Today’s weather map, shown overlaid on the water vapor image below, has not changed much since yesterday. The broad trough<\/span> is now centered over southern Alberta and has only slowly progressed eastward. However, a more noticeable southern end circulation is seen today over northern Arizona. This will be the most notable feature for Colorado’s weather today. A rather broad cloud deck is noted this morning over the southwest part of the state, stretching back into UT and AZ. This cloud deck is an indicator of the synoptic scale upward motion being caused by the disturbance. As it slowly treks northeast into northern NM and CO, solar heating will cause widespread<\/span> showers and thunderstorms across a similar region as yesterday. However, despite fairly high moisture content with Grand Junction’s morning precipitable water<\/span> reading around 0.9 inches, the broad thick cloud deck will likely limit instability more so than yesterday. Although isolated<\/span> heavy rainfall is expected, today’s flood threat is kept at a Low status due to the expected short duration of such rainfall. Instead, light to moderate rainfall is more likely for most of the afternoon and evening hours for most of the western slope and into the northern parts of the Southeast Mountains. East of the Continental Divide<\/span>, dry air from Wyoming will once again limit rainfall chances, although a shower or weak storm will likely prevail closer to the foothills and mountains.<\/p>\n
