For the north-central mountains also isolated rain showers / weak thunderstorms from 1pm-7pm, best chances along/south of I-70.

Best coverage of storms from Leadville to Colorado Springs to Pueblo and south / southeast 12pm-8pm.

For tomorrow (Friday) just some isolated to scattered storms over the north-central / south-central mountains from 2pm-8pm. Den/Bou and the front-range likely remains dry on Fri.

How much rain did you get the last 2 days? How about the last 30 days?

Its actually been a very wet stretch for the northern front-range (including Den/Bou) for the last 1 month...later we will look at some precip total / percentage of average, its been great to see!
