— LOW\/MODERATE<\/strong> flood threat for Front Range, Urban Corridor, Northeast Plains, Palmer Ridge, Southeast Mountains, Southeast Plains<\/em><\/p>\n

— LOW<\/strong> flood threat for Central Mountains, Raton Ridge<\/em><\/p>\n

Fog and low-level clouds this morning for the northeast portion of the state are the result of moist and cooler air over this region. The cooler air and increased cloud cover will help limit high temperatures over this region today, but instability should still be able to build later this morning and afternoon for widespread<\/span> PM showers. Precipitable Water<\/span> (PW<\/span>) is currently over 1 inch over the eastern plains and is forecasted to remain intact throughout the day with the cool, moisture rich air mass moving south. West of the Continental Divide<\/span>, the best moisture will be over southwest region. However, westerly flow at the mid-levels should draw in some drier air from southern Utah that will limit heavy rainfall. The large-scale trough<\/span> will provide west\/northwest flow over Colorado and help usher in shortwaves that will enhance convection<\/span> initiated by upslope flow and outflow boundaries<\/span>. There is an upper-level wind maximum that moves south over our state this afternoon and tonight, that will also help provide lift for showers over the eastern plains into the early morning hours.<\/p>\n

Moisture rich upslope flow is expected to initiate thunderstorms over the higher terrain early this afternoon. Storm coverage will widespread<\/span> east of the Continental Divide<\/span>. As storms move off the mountains, they will initially favor the high terrain of the Palmer and Raton Ridge and have storm motion to the east\/southeast. The storms are expected to quickly form into widespread<\/span>, slow-moving convection<\/span> over the eastern plains and be amplified by a mid-level distrubance. Heavier rainfall is likely near the highest instability, which will be located where daytime heating is the greatest throughout the day. Small hail and gusty winds may be present with the more severe storms. Over the mountains, rainfall rates greater than 1 inch are likely over the Southeast Mountains. Threats include mud flows, debris slides and flash flooding<\/span> especially over burn scars. Over the far eastern plains, localized 24-hour rainfall amounts over 4.5 inches may be possible. Threats include small stream and arroyo flooding, field ponding and road flooding. The threat for the eastern plains last into the overnight hours, and the cluster of storms is expected to exit the state around 3AM. Lingering showers and cloud cover over the plains and southeastern mountains are likely Monday morning.<\/p>\n
