DISCUSSION...Surface analysis shows substantial moisture across eastern CO and into southeast WY, with upper 50s to lower 60s F dewpoints. Daytime heating continues, with weak easterly surface winds maintaining the moist air mass. Lapse rates are not particularly steep today, with warm temperatures aloft, and lack of boundary layer mixing. However, MLCAPE is increasing to around 2000 J/kg, and, 20 to 30 kt mid to high level winds are resulting in effective deep layer shear of 30 kt. As such, mixed storm modes are expected. A strong cell has already developed over western Douglas County as of 20Z, possibly producing hail. Additional activity will likely fill in across the entire region through early evening, and some cells may produce hail over 1.00" diameter. Some of the downdrafts may produce strong to perhaps severe gusts, but an organized wind threat is not anticipated. ..Jewell.. 08/14/2026 ...Please see www.spc.noaa.gov for graphic product...
