08/24/26 8:35am: Morning, its Monday. We do have some weather to talk about with some fairly active days coming up (in terms of thunderstorms).

Models show more monsoon moisture combining with a cold-front that will move down the front-range Tue afternoon / evening into Wed am...these will combine to enhance the thunderstorm chances, especially on the front-range and east of the Divide.

For today (Mon) good thunderstorm coverage across the mountains. On Tue decent thunderstorm coverage across the mountains and also the front-range, later in the day. On Wed best chance for stronger storms on the front-range (including Den/Bou).

For today, scattered thunderstorms across the north-central and south-central mountains form 1pm-9pm, favoring areas generally along/south of I-70 and east of the Cont. Divide.

For tomorrow in the mountains, most of the activity will be east of the Cont. Divide: 12pm-7pm. On Wed not as much coverage over most of the mountains, some east of the Divide again, mostly after 2pm Wed.

For Den/Bou and the front-range more isolated to scattered thunderstorms today (Mon): 3pm-9pm (best chances after 5pm, around the edges). For tomorrow: scattered thunderstorms: 1pm-7pm, favoring the foothills.

On Wed, best chance for stronger / severe storms between 3pm-9pm (could be some hail in spots, favoring areas alon/east of I-25).

It will also be cooler for Den/Bou and the front-range Tue and especially Wed with highs in the upper 70s.

Then looking ahead towards the weekend, the atmosphere dries out and warms up again from Thu-Sun with some hot temp returning to the lower elevations.
