.DISCUSSION...
Soil conditions and KBDI values continue below critical
thresholds, especially in the southern plains and southwestern
coastal areas. The winds will become a little bit stronger today,
coming out of the southeast. However, relative humidities should
stay in the 50%. Therefore, the risk for fire weather will remain
to be low. Passing showers may provide beneficial rain at times.
