The airmass along and north of the warm front was mild, moist, cloudy, moderately windy, with poor visibility. Manchester was in a different airmass with southeasterly winds coming from the dry continent providing clear skies, a dry atmosphere, a cool start with rising temperatures until mid-afternoon, then falling back to cool in the evening, higher pressure gave a light breeze and visibility was excellent.
Learning points: Different airmasses produce very different sorts of weather, they always have done and mostly likely will in the future. When the sun shines in a dry airmass, temperatures increase rapidly in Spring, Summer and Autumn, not so much in the Winter. Greater water (gas, liquid or solid) content in the atmosphere suppresses temperature rise. Sun and water controls our weather, and accumulated weather - climate.
