Daily Diary

Mild, windy, warm sector conditions with overcast skies during daylight hours, this following some overnight rain. Rain during the afternoon increased in intensity through the evening, culminating in an exceptionally sharp cold front with dramatic wind veer and temperature drop which arrived just before 8pm. Further north, across Wales and W/NW England, the temperature drop was even more dramatic, with heavy flooding rains turning very quickly to heavy snow before clearing. Some clear spells followed, and a few showers.
