— LOW flood threat for portions of Northeast Plains<\/p>\n

A strong disturbance moved into western North America over the past few days, and will influence our weather beginning today. The water vapor image, below, shows that the main circulation is located in southern Saskatchewan today. Draped to the southwest is a trough<\/span> axis that extends into the Great Basin. As this disturbance approaches Colorado, it will cause large-scale lift and generate plenty of showers and thunderstorms. West of the Continental Divide<\/span>, limited instability will keep rain rates below flood-prone intensity. East of the Continental Divide<\/span>, a pocket of higher moisture exists in northeast CO today. Acting against this is a plume of very dry air being advected from the southwest by a strong subtropical jet. This will limit the heavy rainfall threat to areas along the Nebraska border. Also acting against the flood threat will be very swift storm motions, above 40mph. Nonetheless, a Low flood threat has been issued for parts of the Northeast Plains for isolated<\/span> flash flooding<\/span>.<\/p>\n

Perhaps the bigger story today will be the potential for severe weather – most notably gusty winds up to 75mph and large hail, up to 1.5 inches. These hazards will occur with the strongest storms. However, overall, expect windy conditions across northern Colorado today as high jet stream<\/span> speeds get mixed downward into the boundary layer<\/span> courtesy of solar heating.<\/p>\n
