.DISCUSSION...
The very hot and dry conditions continue through the rest of the
week. High pressure overhead will act to increase temps each day.
Combined with continental air mixing into the region, expect dry
vegetation to further feel these effects. Daily RH minimums will
range from 30 to 50 percent. Lower humidity to the north and
higher towards the coastline.
