.DISCUSSION...

A warm front will move into the area tonight into Friday, which will 
increase humidity and allow for a wetting rainfall to occur. 
Scattered showers will continue for Friday and into Saturday until 
the front moves through and high pressure builds in midday Saturday. 
Winds will be slightly elevated from the southwest Friday evening 
and turning northwest on Saturday behind the front around 5-10 mph, 
with gusts of 15-20 mph. Despite the wind shift and high pressure 
building in, RH values are not expected to be critically low, but 
will be around 30-40% Sunday/Monday. Dry weather continues through 
late Tuesday, when another larger system moves into the area 
bringing rainfall once again.
