.DISCUSSION...Light terrain driven winds mainly under 12 mph through
Wednesday with minimum relative humidities of 12 to 22 percent. A
low pressure system will likely cross the region by this weekend,
though recent trends have shown a delay in its arrival. Current
forecast keeps Friday warmer and drier than previously advertised
with cooler and wetter conditions arriving Saturday, though may be
delayed until Sunday if the system continues to slow. Winds will
likely increase and turn southwest with the arrival of the low.
