.DISCUSSION...
As high pressure dominates the region though much of this week,
we will see temperatures above average with daytime highs well
into the 90s and overnight lows in the upper 70s. Drought
conditions have depleted fuel moisture and rain will continue to
be very difficult to come by for many areas outside a stray
shower or thunderstorm during peak heating hours. Lowest daily RH
values will remain in the mid 40 to 60% range through the week.
