***Scattered thunderstorms in the Sierras again today***

Some remnant moisture from former tropical storm Hernan has entered the central part of the state.  This has resulted in a few thunderstorms during the early morning hours around Fresno and the foothills south of the French Fire.  These storms will dissipate by 9 am, but further thunderstorm activity is expected in the Sierras once again this afternoon.  The storms should develop mainly along the Crest before moving slowly to the northeast this afternoon.  Other areas from Los Angeles County northward will see abundant high clouds which may hold temperatures down a couple of degrees from yesterday.  Overall, expect high temperatures to reach the 90s in the valleys and foothills to 110 in the low desert.  Winds will remain light.  Some mid slope areas from 1,500 to 5,000 feet may see RH drop into the teens for 4-6 hours during the middle to late afternoon.  Thursday and Friday, expect less high cloudiness, but overall the weather will change very little through the end of the work week.  This weekend, models suggest a plume of subtropical moisture may reach the southern part of the state.  This may result in scattered wet thunderstorms returning to the deserts and nearby areas of the San Bernardino, Cleveland and Angeles National Forest Saturday and Sunday.  Conversely, the Sierras should see an end to the afternoon thunderstorms by Friday.  Temperatures may trend a bit cooler over Central California this weekend with a return of the marine layer.  Next week looks cooler and drier at this point.

Fuels/Fire Potential

Scattered thunderstorms in the Sierras will likely generate gusty, erratic winds in the vicinity of the fires.  Downsloping, terrain-channeled winds may be possible at the French Fire due to convection in the area.  Although the threat of new starts will continue to be lower this week due to less lightning, any new start will have the potential for rapid growth through all fuel types due to the exceptional drought covering most of the area.  This weekend, the highest potential for new starts will shift southward into Southern California as another surge of monsoon moisture is expected to arrive.  Moderate IA and resource demand is expected in Central California through Friday, then moderate IA will develop over Southern California during the weekend.
