Saturday was interesting in Reading, around 3-4pm it went from nice sunshine to very dark and ominous, I was at work trying to sell a house before the end of the day and I was driving to the east of Reading and thought this cell has all the makings for a thunderstorm, looked at the maps and there was nothing, suddenly 3-4 bolts of lightning came from the cell and it kicked off, had good regular lightning for about 20 mins before it passed over the east, had a few land relatively close to where i was, it stopped anyone coming to view this house till it passed so was cool standing in the doorway and watching it go over. Literally was nothing until it got to Reading and then it just started to unleash some real energy, pretty sure there was hail in a later storm shower that happened on Sunday too.
