Anyway, for the rest of today, pretty dry and warm across much of the state with a chance for storms closer to the front-range.

In the mountains some isolated storms this afternoon, mostly east of a line from Granby to Monarch Pass (north-central and front-range mountains): 2pm-7pm.

For Den/Bou and the northern front-range a chance for isolated to scattered storms from 4pm-8pm again, hit or miss rain.

Third image shows forecast radar at 6pm today from latest HRRR.

Looking ahead it will be dry and warm across the state for Wed-Fri. Windy at times over western CO on Wed and Thu (with a weak wave to our west).

Then tracking a stronger / colder storm system that will impact the state from late Fri night and mostly through the day Sat.... heads up Sat could be rainy (snow above 10k ft) in the mountains, favoring southern CO (southwest flow). More on that soon.
