Planning Outlook
A changeable southwesterly regime onward into early next week. Milder air and thawing into Sunday, accompanied by rain and upland gales. A drop of freezing level onto higher mountains develops during Monday into Monday night; weakening fronts bringing some precipitation, but fading. Higher pressure nearby and commonly drier conditions during early March, though an occasional front coming in from the west may bring some rain later in the week ahead. Varied wind speeds, extensive lulls mixed with some windier days. Milder air is likely to return from the south more often.
