Issue Date: 6\/1\/2019
\nIssue Time: 8:55 AM<\/p>\n

A LOW FLOOD THREAT IS FORECAST TODAY FOR PORTIONS OF THE FRONT RANGE, URBAN CORRIDOR, PALMER RIDGE, NORTHEAST PLAINS, AND SOUTHEAST PLAINS.<\/em><\/p>\n

On the first day of Meteorological Summer, the large-scale weather pattern features an upper-level low sinking southward along the West Coast, allowing for a building ridge of high pressure over the southern\/central Rockies. Embedded in the southwest flow aloft between these two pressure centers is a ribbon of decent mid-level moisture that will continue to overspread Colorado. This moisture will be the fuel behind a few scattered<\/span> showers\/weak thunderstorms along\/west of the Continental Divide<\/span> today, all of which will be high-based owing to a lack of low-level moisture. Light precipitation and gusty winds will be the main impacts associated with this activity.<\/p>\n

\"\"<\/a><\/p>\n

East of the Continental Divide<\/span>, and mainly along\/east of the Front Range\/Southeast Mountains, easterly upslope flow will usher in the return of surface dewpoints in the 40s\/low 50s. This increase in moisture, coupled with good daytime heating, will allow for the development of scattered<\/span> thunderstorms across the area. There will be enough instability for a few of the storms to become strong\/severe, with the highest relative risk over the far Southeast Plains where the combination of instability\/wind shear<\/span> will be most favorable. The main threats will be strong winds and hail up to 2 inches in diameter; an isolated<\/span> tornado or two cannot be ruled out.<\/p>\n

Zone-Specific Forecasts<\/strong><\/h3>\n

Front Range, Southeast Mountains, Urban Corridor, Northeast Plains, Southeast Plains, Palmer Ridge, and Raton Ridge:<\/strong><\/h4>\n

Scattered<\/span> thunderstorms are expected today, beginning around lunchtime over the Front Range and Southeast Mountains, spreading eastward with time over eastern Colorado. A secondary focus for initiation besides the higher terrain will be a weak surface boundary over the far Southeast Plains; this boundary is the reason for the higher, relatively speaking, severe threat today as mentioned above. The main threats will be strong winds and hail up to 2 inches in diameter; an isolated<\/span> tornado or two cannot be ruled out. Maximum rain rates are as follows:<\/p>\n

Front Range: 0.6-1.0 inches\/hour
\nSoutheast Mountains: 0.4-0.6 inches\/hour
\nUrban Corridor: 0.8-1.2 inches\/hour
\nNortheast Plains, Southeast Plains, and Palmer Ridge: 1.5-2.0 inches\/hour
\nRaton Ridge: 0.5-0.8 inches\/hour<\/p>\n

Timing: Noon – 9 PM for the Front Range and Southeast Mountains, 1 PM – 10 PM for the Urban Corridor, 1 PM – 11 for the Palmer Ridge, and 1 PM – Midnight for the Northeast Plains and Southeast Plains<\/p>\n

Northern Mountains, Northwest Slope, San Luis Valley, Central Mountains, San Juan Mountains, Grand Valley, and Southwest Slope:<\/strong><\/h4>\n

Scattered<\/span> showers\/weak thunderstorms are expected today as daytime heating and orographic effects work on good mid-level moisture. Due to a lack of low-level moisture, activity will be high-based, with the main impacts being gusty winds, light rainfall, and occasional lightning. Rain rates will generally be less than 0.1 inches\/hour everywhere, with maximum rates of 0.15-0.30 inches\/hour over the San Juan Mountains and Southwest Slope.<\/p>\n

Timing: 11 AM – 9 PM, with an isolated<\/span>, lingering shower or two until 11 PM over the higher terrain<\/p>","protected":false},"excerpt":{"rendered":"
