Strong westerly upper flow persists across the British Isles, but gradually becoming more amplified with time allowing cold air aloft to spread farther south. This will result in very steep mid-level lapse rates and a few hundred J/kg CAPE. Once the main frontal precipitation clears to the North Sea by early afternoon on Sunday, numerous wintry showers will follow - most frequent in western parts, but moving well-inland on strong steering winds. Sporadic lightning, small hail and gusty winds will accompany some of these showers.
