Planning Outlook
Sunday will be increasingly wet for all, then Monday substantially dry though showers into northern areas will continue with snow and hail onto high terrain. Temperatures stay cold into early next week; higher summits of England and Wales close to freezing point and Scottish summits all below freezing - snow is expected. Westerlies will begin to re-establish on Tuesday, allowing temperatures to rise and focusing rain and showers onto western slopes. Eastern areas will be often dry with bright or sunny periods through mid-week, though some rain and cloud will slip east. Indications of winds shifting southerly later in the week and into the weekend, brining a further rise in temperature and a risk of several low pressure systems drawing bands of rain across the country from the south and southwest.
