.DISCUSSION...
Temperatures will be in the upper 60s today and tomorrow with min
RHs sitting around 35 to 40%. Winds will be mainly light today
but there may be a couple of gusts up to 15 mph this afternoon.
Southwesterly wind gusts up to 15 mph are more likely tomorrow
afternoon. Winds shift to northwest on Sunday, sustained at 10 to
15 mph with gusts potentially around 20 to 30 mph. The stronger
winds will blow more moisture into the area, so the min RHs should
increase to around 50 to 55%.

Rainfall will come as spotty showers and there is no guarantee
for rain at the fire. However, if there is a shower, it can bring
0.05" to 0.15" of rain, so wetting rain is not completely
impossible, but unlikely. There is a chance for a thunderstorm
around the fire this afternoon. The most likely scenario is that
the storms remain north/east of the fire. If this does occur, an
outflow boundary can bring brief gusty and erratic winds.
