Snow Level Drops to 1500 Feet, Thunder Could Come
To put this in perspective, the San Fernando Valley's elevation varies between about 250 and 1200 ft, so says Wikipedia. Between 3 a.m. and 9 a.m., tomorrow, a frost advisory--meaning at least two hours of subfreezing temperatures--has been issued for the San Fernando Valley and other areas in the region, according to the National Weather Service who says there "is the potential for increasing rainfall intensities and even a slight chance of thunderstorms. Some of these showers could produce bursts of heavy rainfall." For recent burn areas below the snow level, the flash flood watch remains until at least 8 p.m. tonight.
