The cold front mentioned in previous forecasts will bring a slight chance for scattered showers to the region overnight. Recent model output suggests totals only around a few hundredth's of an inch, so the largest impact for Sunday's on track sessions might be some damp areas early. The cold front is not expected to pass through the region until the late afternoon or evening, allowing plenty of time for temperatures to warm to the upper 70's. Mostly cloudy conditions are expected overnight, with partly cloudy skies expected during the day; clouds will be mostly in the mid-to-upper levels. Windy conditions are likely with some stronger gusts possible, maximum winds will occur on the edge of the front; until the front passes, winds will be from the west to southwest.
