URGENT - FIRE WEATHER MESSAGE
National Weather Service Medford OR
1141 AM PDT Sat Jul 20 2024

.An upper level low will move up from the south along the
California coast late this afternoon, and will tap into
increasing mid-level moisture. Meanwhile, elevated instability
will increase and this combined with a moderate to strong trigger
could result in isolated to scattered thunderstorms this evening
into Sunday morning, and again Sunday afternoon and evening. Given
how dry fuels are, along with continued hot temperatures,
lightning efficiency will be high to very high for fire starts.
