LOW FLOOD THREAT IS FORECAST FOR PORTIONS OF THE FRONT RANGE, NORTHERN MOUNTAINS, AND NORTHWEST SLOPE.<\/em><\/p>\n

The upper-level low currently centered over California will continue its slow shift eastward today, bringing deep southwesterly flow aloft across Colorado. This southwesterly flow will continue to stream mid- and high-level moisture across the area (along with an embedded mid-level disturbance), bringing an increase in clouds and precipitation during this period, especially to the High Country. Storms will mainly be high-based across the mountains, which will provide more gusty winds than rain, and plenty of virga<\/span> will be noted. Near the CO\/WY border, the threat of heavy rain will exist where the best overlap of moisture, lift, and instability will occur. As indicated in the Precipitable Water<\/span> chart below, moisture over western Colorado is above the 90th percentile (as measured at Grand Junction) for this date. With that consideration in mind, the inclusion of a low-end, low flood threat is warranted.<\/p>\n

Further east over the lower elevations, “inverted-V<\/span> soundings” are noted this afternoon and evening, which will limit precipitation but enhance the risk for strong winds\/microburst activity. The best chances for this activity will be along\/near favorable terrain, such as the Urban Corridor, western portions of the Southeast Plains, Raton Ridge, Palmer Ridge, and the Cheyenne Ridge. Rain rates will remain on the low side; details are given in the zone-specific forecast discussions below.<\/p>\n

As we move into the evening and overnight hours, storms will diminish from south to north across the lower elevations as drier air moves in from the south\/southwest. For the higher terrain, isolated<\/span> showers and perhaps a few weak thunderstorms will continue overnight and into tomorrow morning.<\/p>\n
