.DISCUSSION...

Showers and thunderstorms are ongoing to the west of the site.
This activity is beginning to diminish but may hold together long
enough to produce light rainfall over the area in roughly 45-60
minutes. Winds will pick up slightly out of the west in that
timeframe with gusts around 25 MPH likely as the outflow moves
through. Otherwise, relative humidity will increase to around 100%
overnight as winds become light and variable. Chances for showers
and thunderstorms will increase to around 40% during the
afternoon hours Sunday. Gusty winds and heavy rainfall is possible
with any passing storm. RH values fall to around 60% during the
daytime hours before rebounding back to 100% overnight. Transport
winds generally 5-10 MPH out of the west-northwest over the next
couple of days.
