Isolated thunderstorms moving down from the north will bring a threat of gusty outflow winds into this evening across mainly the northern/central sections of the region. Moisture will increase further on the Fourth of July leading to isolated valley/scattered mountain thunderstorms, mainly during the afternoon and evening hours. Gusty outflow winds will remain a threat with any thunderstorm activity. Thunderstorm chances will increase further Friday and Saturday as additional moisture works into the region. Temperatures will remain at above seasonal levels into the weekend.   (Please visit for more information.)
