Direction of light winds through 9 AM may be more variable and terrain-dependent, but direction should become more stable by late morning out of the northwest as the mixed layer deepens and gusts develop. Occasional gusts 20 to 25 mph will be common through the afternoon as the relative humidity drops to 30 to 35 percent. The deep mixing and breezy winds will lead to excellent smoke dispersal by 10 AM CDT. Looking ahead to Thursday, winds will be lighter and favor more of a westerly direction by midday. Deep mixing will again result in excellent smoke dispersal from late morning onward. Humidity levels will be lower on Thursday, dropping as low as 20 percent by late afternoon. .REST OF TODAY...
