— A LOW<\/strong> flood threat has been posted for parts of the Front Range, Palmer Ridge, Central Mountains, San Juan Mountains and Southeast Mountains<\/em><\/p>\n

A persistence-type weather pattern continues over Colorado for today. The trough<\/span> of low pressure has moved only slightly eastward over the past 24 hours, and near-surface and column moisture remains virtually unchanged. This morning’s PW<\/span> at Denver dropped slightly from 0.72 to 0.69 inches, while Grand Junction stayed unchanged at 0.64 inches. The main difference in today’s weather setup is the presence of more widespread<\/span> cloud cover over southeast Colorado due to a cut-off low<\/span> over New Mexico. This will tend to suppress heavy rainfall over the southern portion of the Southeast Mountains today. However, aside from that, the persistence pattern warrants the continuation of a Low flood threat over the higher terrain of southern and central Colorado. A moist atmospheric column, instability up to 700J\/kg and sufficient southerly wind shear<\/span> will support 30-60 minute bursts of heavy rainfall up to 1.0 inch per hour. This is capable of causing isolated<\/span> flash flooding<\/span>, debris flows and mud slides over steeper terrain. East of the Continental Divide<\/span>, away from the higher terrain, a slight decrease in rainfall activity is expected due to weak subsidence to the west of the low pressure trough<\/span>.<\/p>\n
