.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.
