Planning Outlook

Cool and showery westerlies into the weekend, windy over high terrain; western hills often capped in cloud. Southern Pennines and Wales likely see only scattered showers and remain warm. Cloud encroaches from the southwest on Sunday, winds turn southerly and warmer air wafts back across England and Wales. A complex area of low pressure is then expected to circulate slowly over Britain early next week, bringing areas of rain and heavy showers, some thundery downpours possible. Winds varying, trending northerly and strengthening, to gales over high summits on Tuesday. A window of improvement from midweek, which may persist into the weekend, but a showery northwesterly persists in Scotland. Beware ongoing fire management restricting access to some mountains.
