— Moderate flood threat for Palmer Divide<\/span> and Southeast Plains
\n— Low flood threat for Northeast Plains, San Juans, Raton Ridge and Southeast Mountains<\/em><\/p>\n

Moisture has substantially increased over all of Colorado in the last 24 hours. This is courtesy of the remnants of Hurricane Dolores, which is currently spinning just off the southern California coast (see water vapor image below). Certainly a rarity. Precipitable water<\/span> values (PW<\/span>) climbed from the 0.6 – 0.8 range yesterday into the 1.0 – 1.3 inch range this morning. These values are very high, and certainly support a heavy rainfall threat. However, not all ingredients are supportive of heavy rain today. A thick cloud deck this morning across western and central parts of the state will limit solar heating, and thus, atmospheric instability. However, the southeast quadrant of the state is mostly cloud free, which is where most of today’s action will be. This will also be aided by a weak front that is expected to develop along and south of the Palmer Ridge, courtesy of the diurnal lee-side low pressure circulation.<\/p>\n

For today, we expect mostly cloudy skies to continue over and west of the Continental Divide<\/span>. Meanwhile, sunny skies will lead to scattered<\/span> thunderstorms over the Palmer Ridge and stretching southwestward into the San Juans. A Low flood threat is in place for these regions. Farther east, towards the Kansas border, storms will intensify by early evening, paving the way for a very heavy rainfall threat. A Moderate threat is in place for this region.<\/p>\n
