Planning Outlook
A settled spell of weather onward through late week into the weekend, with increasingly warmer temperatures on the hills, reaching 10C+ on many tops. Valleys and some sheltered higher areas will start with a risk of frost but increasingly by the afternoons many valleys will warm up toward 20C, particularly in the west. Briefly cooler air may extend back into northeastern areas over the weekend. Strong April sunshine widely across the mountains, beware risk of sunburn. Misty starts in some valleys. After a gusty easterly during midweek, the wind will drop light for most places by late this week. A settled springtime outlook is likely for next week.
