...MOISTURE INCREASING THROUGH SATURDAY...
.BROADCAST DISCUSSION...Moisture will increase significantly
from south to north through Friday, bringing increased chances
for wetting rains and increasing humidity. Moisture will linger
over the area through Saturday, with a drying trend following for
early next week.
.DISCUSSION...With southerly flow across the area, monsoonal
moisture will be drawn upward into the area from south to north
through Friday. The presence of this moisture will bring
increasing coverage of afternoon and evening showers and
thunderstorms with a higher potential for wetting rains,
particularly on Friday. Moisture could begin to decrease as early
as Saturday, with a more pronounced drying trend expected to
commence on Sunday.
