— <\/em> LOW<\/em><\/strong> flood threat for Southwest Slope, San Juan Mountains, Northeast Plains<\/em><\/p>\n The monsoon<\/span> moisture plume sticks around for another round of thunderstorms today. The Denver sounding this morning had 1.13 inches of Precipitable Water<\/span> (PW<\/span>), while the Grand Junction sounding had 0.93 inches with more drying in the mid-levels. Dew points<\/span> over the eastern plains are as high as 65F and are also still high over the southwestern corner of the state. The high PW<\/span> is marked in the water vapor image below. The mid-levels may dry out a bit over the course of the day with winds from the north, but not enough to limit heavy rainfall again this afternoon. Cloud cover continues over the southern and central mountains as well as the southern Urban Corridor, Palmer Ridge and Southeast Plains. The cloud cover will help limit temperatures again today, but has a much better chance of at least partially burning off by the afternoon allowing some instability to build unlike yesterday. With the ridge off to our north over Canada, light westerly flow will be present at the upper-levels.<\/p>\n Expect storms to start firing off the higher terrain just after noon to the north and a bit sooner over the south. Storms will begin to slowly move off the mountains onto the adjacent plains in the late afternoon likely favoring the higher terrain of the Palmer Divide<\/span> and Raton Ridge. Storm motion will be 10-15 knots moving E\/SE. Rain rates over the mountains will be as high as 1.3 inches in 1-hour with 3 to 6-hour totals up to 2 inches. There is a chance storms forming over the Cheyenne Ridge may move over the border into the Northeast Plains.<\/p>\n Over the San Juan Mountains, storm totals around 2 inches will warrant a Low flood threat with the antecedent rainfall. Heavy rainfall again today will create dangerous conditions over already saturated soils and burn scars. Threats include mud flows, debris slides, small stream and road flooding, so burn scars need to be watched carefully again today. Over the adjacent plains, expect storms to have max 1-hour rain rates up to 2.25 inches with 3-6 hour totals up to 4 inches. Threats include arroyo and street flooding as well as field ponding. Storms over the mountains should end a couple hours after sundown, while storms over the SE corner of the state will continue until midnight.<\/p>\n <\/p>\n
