With temperatures gradually cooling, humidity levels will increase
through Monday resulting in chances for showers and thunderstorms
with modest chances for wetting rainfall. There is a 50% chance of
gusty outflow winds sweeping across the wildfire site late this
afternoon and early evening as a result of storms south of the
area. The best chances of wetting rain will arrive tonight through
Monday morning. Much drier air will move into the region Tuesday
though cooler temperatures will allow humidity levels to remain
somewhat elevated.
