.DISCUSSION...Drier air has moved into the region along with less lift
thanks to the low pressure shifting away from our area. A brief isolated
storm can`t be ruled out (10% chance) this afternoon. These can still
produce gusty and erratic winds along with frequent lightning.

The moisture doesn`t fully depart our area over the next several days so
that will keep a small (~10%) chance of storms each afternoon along with
relative humidity above critical conditions. Winds will remain light and
diurnally driven as well. Moisture doesn`t increase over the region
until the end of the upcoming week.
