The burn site will still see quite a bit of cloud cover through the day, with a combination of both mid and upper level cloudiness. Winds will be out of the southwest to west ahead of an approaching cold front. This front will weaken and possibly wash out this afternoon as it approaches the burn site. However winds will not diminish with the front, with wind speeds through the day up to 15 mph and wind gusts between 25-30 mph. Transport winds will also continue to be strong today. .REST OF TODAY... Sky/weather.........Mostly cloudy (65-75 percent). Chance of pcpn......10 percent. LAL.................No Tstms.
