Note, I’m at the end of a 2 week family camping vacation near Red Feather Lakes, CO at this time. Internet availability is very limited, so these discussions are shorter and simpler than normal.
The moisture is finally here and the temperatures are down a bit. As I write (internet of opportunity at the library) the afternoon storms have yet to form on Thursday, but hopefully Longmont saw some rain.
Figure 1 shows the returning moisture from the deep southwest as the high pulls off to the east. The severe weather chances are minimal and would be brief under heavier cells, but both Friday and Saturday, storms are expected to be more of the normal storm strength (Figures 2 and 3).
The longer range forecast:
A short wave ridge crosses the state on Saturday and depresses storm chances. A bit of moisture returns Sunday and beyond—temperatures return to just a bit above normal with afternoon thunderstorms chances.
