Better chances of rainfall may remain just east of the incident with only modest chances of wetting rainfall. The best opportunity for rain will occur this evening and overnight. Good overnight recovery will be followed by slightly drier conditions Tuesday. Although temperatures will be much cooler through the middle of the week, a dry airmass will sweep back across the wildfire site allowing minimum humidity levels to fall back into the teens. ...Thunderstorms imply gusty winds...
