30% chance that temporarily between 4 in the afternoon and 8 in the evening it will deteriate to visibility of 4000m in heavy showers of rains and heavy thunderstorms and rain, cloud lowering to broken at 800ft cumulonimbus

I was with friends at Hebden all day and at 17:00hrs we had all of that - TS, heavy rain, low cloud etc. Driving home with the temperature at 11.5C we had radiation fog forming
it looked quite pretty floating gently about 6" above the fields and between the trees. It also poured down whilst we spent a couple of hours at Brimham Rocks.
For anyone who may not be too familiar with the geography of the UK, Hebden and Brimham Rocks are places in the Yorkshire Dales National Park.
