.DISCUSSION...
Upper level high pressure takes control of our weather and
persists through most of the week. While an afternoon shower or
thunderstorm will be possible, hot and dry conditions are more
likely, with any wind gusts generally around 15 MPH or less.
Minimum relative humidity should also mostly stay above the 35 to
40 percent range.
