.DISCUSSION...

...Dry weather through the weekend to give way to widespread
rainfall early next week... 

High pressure will continue to keep our weather pattern dry heading 
into and through the weekend. A potent cold front will approach and 
cross the region Monday into Tuesday, bringing a return of showers 
and gusty winds to the region. Drier weather returns to the area by 
the middle to end of next week.

Minimum relative humidity values will be near 30 percent through
the end of the week before moisture starts to increase over the 
weekend. Light transport winds and a relatively shallow mixing height
will create poor dispersion and ventilation conditions into the 
weekend.
