For this evening, it looks like isolated to scattered showers/tstms will be seen over the southwest mtns, San Luis Valley and the Sangre de Cristo mtns, with isolated to scattered showers/tstms being possible over the Wet mtns, Pikes Peak area and the I-25 corridor. Then by late evening the NAM and the HRRR show some storms moving out over the far sern plains, mostly ending by 1 am. Sun morning looks dry acrs southern CO, with storms then developing over the mtns in the early afternoon and possibly spreading to the adjacent lower elevations. Temps in the high valley areas on Sun look like they will be similar to today. Over the southeast plains, temps should be warmer than today by several degrees. .LONG TERM...(Sunday night through Saturday) Issued at 239 PM MDT Sat Jul 1 2017 Not much change to the forecast thinking through the extended period. Models are in good agreement and ensemble spreads are low leading to continued higher confidence forecast. Sunday night through Tuesday...high pressure will begin building northward out of the Desert Southwest and across Utah through this period. A slow moving upper disturbance over Eastern Colorado into Western Kansas will keep flow northwesterly. Expect ongoing showers and thunderstorms Sunday night rolling off the mountains and across the Plains through the evening hours. Favored areas continue to look like the Palmer Divide and Raton Mesa. A few storms could become strong to near severe levels with hail approaching 1 inch in diameter and 60 mph winds.
