Planning Outlook
Extensive rain and gales into midweek, likely wettest on west-coastal regions. Areas of rain and showers frequently in the forecast later in the week. Temperatures near-average, but feeling cool when exposed to wind. A chillier northwesterly may emerge by next weekend, briefly dropping near freezing on the highest Scottish tops. Indications then favour higher pressure at least briefly expanding northwards early next week for some drier days, but unlikely to settle down for long.
