.DISCUSSION...

Primary concern for today will be an area of convective showers
expected to move in from the southwest this evening into the
overnight hours. Forecast soundings highlight the potential for a
few isolated lightning strikes and a brief period of gusty winds,
particularly during the onset. Shower activity clears out by
Sunday morning, but west to northwesterly breezes pick up in the
wake of the passing disturbance. There is over an 80% chance for
at least incidental wind gusts of 25 mph or greater.
