.DISCUSSION...
As high pressure dominates the region though much of this week.
We will see temperatures above average with generally daytime
highs from 90-100 and overnight lows in the upper 70s, and rain
will be very difficult to come by for many areas. Winds will be
calm to light and variable overnight and 5-10 mph out of the
southwest to southeast during the day. Lowest daily RH values
will remain in the mid 40 to 60% range through the week. The
upper ridge aloft may begin to weaken late week into the weekend
which would allow for greater convective coverage and more near
normal temps.
