Forecast for the week: cooler on front-range, best storm chancs Tue and Wed

06/23/25 10:15am: Morning, its Monday but its least its about 20-30 degs cooler on the front-range this morning compared to Saturday!, with some low clouds / fog in spots. Was only 59 at my house in Westminster when I left this morning, currently 63 in Boulder as the low clouds start to move out. We are in for some cooler weather especially along the front-range over the next 3 days with better rain chances. Best chances will come tomorrow.

Not much action for much of the north-central mountains, especially west of the Divide (just some more comfortable / cool temps) until Wed (best chances for mountains on Wed).

For Den/Bou and the northern front-range for today, highs in the low 70s and then a chance for some isolated to scattered thunderstorms between 4pm-10pm, best chances from Denver north and along/east of I-25 (about 40% chances today).

Then for Den/Bou and front-range tomorrow a much better chance for scattered storms from 1pm-9pm (best chances 2-6pm tomorrow: 50-60% chances in most areas), best coverage south and southwest of Denver tomorrow (foothills, PD).

For the north-central mountains today, seasonable temps, then a slight chance for an isolated storm this afternoon 3pm-8pm, best chance along/east of the Cont. Divide (Front Range mountains).

For the mountains tomorrow a better chance for scattered storms from 12pm-8pm (best chances after 3pm). Best coverage will be over south-central / southeast CO, mostly east of a line from Silverthorne to Buena Vista to Alamosa (and some in the San Juans). Unfortunately not much rain expected over western CO (dry west of Edwards)

Actually looks like best chances for the north-central mountains and parts of western CO will come on Wed: 12pm-8pm as another surge of moisture moves through (so Wed likely wettest day for mountains, less for Front Range on Wed)

Then back to warm and dry conditions from Thu-Sun

First image loop shows forecast radar over the next 48hrs (6am this morning through 6am Thu). Secon image shows forecast total liquid precip over the next 48hrs from HRRR, take with grain of salt but you can see where heaviest rain is expected with the monsoon surge (New Mexico). Image 4 shows current temperature analysis with the cool air over CO (hot to the southeast). Fourth image is current local satellite / surface map overaly showing the low clouds and cooler temps on the front-range.
