Another hot, dry, and windy day will lead to critical fire weather conditions across the southern foothills and Palmer Divide and through the rest of the southwestern part of the state. Please avoid creating fires. Much of the state will be smoky from ongoing wildfires.
Critical fire weather conditions from South Park and points south/west will gradually ease this evening as winds decrease. However, areas of smoke from wildfires burning in southern Colorado will hover across the area through the night. Isolated strong thunderstorms will be possible over the northern plains, possibly starting around Fort Collins and Greeley late this evening and then moving east/northeast.
