.DISCUSSION...
Drier air will remain in place across the region
through Saturday with minimum RH values ranging from 30-40% away
from the immediate coast both this and Saturday afternoons. Moisture
will increase once again Sunday into Monday.
The latest drought map has a one class degradation across SWLA and
parts of lower Acadiana. With little to no rainfall expected through
the period, it will not be out of the realm of possibility to see
another class degradation next week.
