...Drier and cooler today then warming up through next week...

.DISCUSSION...
High pressure will build over the area today, and remain in
place through Saturday. The high will move to the east by
Sunday, and allow southerly winds to increase. These will
bring warmer and more humid conditions to the area. Small chances
of rain will be possible, but most of the time will be dry.
