Dry and warmer conditions are expected Wednesday and Thursday. A
cold front will move across northeast Colorado Thursday night
with much cooler temperatures on Friday over lower elevations
along with a slight chance of showers over the far northeast
plains. Dry and warmer again for the weekend and into early next
week.

Gusty westerly winds, low relative humidity and above normal
temperatures may lead to elevated fire danger again across the
northern mountains and northern foothills Thursday and Friday and
possibly into the weekend.
