Turning rather cloudy with occasional showers. Summit gales.
Clear then brighter spells mixed with a few isolated light showers overnight and early Thursday morning. Cloud increasing from late morning as showers turn more frequent for the afternoon, perhaps becoming heavy across northern most ranges, bringing a small chance of thunderstorms. Showers dwindling during the evening.
