.DISCUSSION...
Hot conditions are expected across the CWA through the forecast
period, with POPs nearly zero through midweek. Daily RH minimum
values will range from 35 to 50 percent across the area this week.
Surface high pressure over the northern Gulf will keep winds light
out of the southwest through the period. With very little to no
rainfall expected for the duration of this forecast period,
worsening drought and fire weather conditions could be possible.
