The light winds aloft mean there is little wind shear that would lead to dangerous "super-cell" thunderstorms - so the threat for tornadoes is low. However, the light winds aloft also mean that the storms will not move away very fast, so local flooding will be the main threat, along with loads of lightning.

The best chance for storms will be in the mountains and along the I-25 Corridor. The atmosphere will be more stable over the eastern plains, so thunderstorm chances will be lower east of a line from Fort Morgan to Limon.

This weather pattern will linger through the week, so expect sunny mornings, building mid-day clouds and late afternoon and evening thunderstorms through at least Friday.

Highs will be in the upper 80s to low 90s on the plains and in the 70s to low 80s in the mountains. Nighttime lows will be in the upper 50s to mid-60s for lower elevations and in the 40s to low 50s in the mountains.

Saturday will be a little hotter and drier, while more thunderstorms and slightly cooler weather can be expected for Sunday.

Hotter and drier weather will return early next week.
