...HOT AND WINDY THE NEXT TWO AFTERNOONS...
.Hot weather and windy conditions in the afternoons will cause very high fire danger across portions of eastern Colorado in areas that have not had much recent rainfall. The winds will be strongest on the plains and in the southern Front Range foothills on Tuesday afternoon, along with humidities of 10 to 15 percent. On Wednesday, the winds will not be as strong, but it will be drier, with humidities as low as 8 percent. In the areas with greener grass, there is still potential for fires to move quickly due to the wind, but the fuel moisture will reduce this potential.
