Planning Outlook

Cool and showery westerlies late this week and into Saturday, windy over high terrain; western hills often capped in cloud. Rain may encroach from the southwest on Sunday, winds turn southerly and warmer air wafts back across England and Wales at least. 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, may strengthen northwesterly by Tuesday to gales. An improving trend into midweek, but showery westerlies likely prevail in Scotland at least. Despite spells of rain, beware ongoing fire management restricting access to some mountains.
