Key Messages
- Dry today, though cooler with few clouds following a backdoor cold front.
- Unsettled tonight through Thursday, with several opportunities for showers and thunderstorms. Timing which days may have better storm chances is still lower confidence.
- Mix of clouds and sun with diurnally driven spot showers Friday into the early part of Labor Day weekend, but drier weather most of the time. Dry and seasonable Sunday and on the Monday holiday, with onshore breezes.
