.DISCUSSION...
Scattered showers and thunderstorms are expected to develop each
afternoon through the upcoming weekend as a weak frontal boundary
stalls near the area. RH values will remain well above critical
thresholds and winds will remain light through the period. The
front is projected to push offshore early next week. This will
allow slightly drier air to feed into the area. Rain chances will
diminish to only isolated showers and storms and RH values will
fall into the 40 to 50 percent range north of I-10.
